Observations on the biology of Stenasellus virei (Crustacea Isopoda Asellota of subterranean waters), 1975, Magniez Guy
St. virei has been bred in the laboratory for many years (1960-1974). Most of the St.v.hussoni were captured in karstic waters, near the Moulis subterranean laboratory. Some St.v.virei from the Padirac sink-hole; St.v.buchneri from Cantabrian caves; St.v.boui and St.v.virei from phreatic waters; and St.buili and St.breuili have also been bred. Since Stenasellids are unable to swim, very low aquariums are used, with a bed of cave clay, some calcareous stones, dead wood and dead elm tree leaves. Little depth of water is necessary. Stenasellus was originally carnivorous, being able to capture and devour living prey, such as Chironomid larvae, but the populations of cave waters have developed a different diet: silt, guano, plant remains..., because they have been often insulated from their original phreatic biocenosis. Nevertheless, the existence of cannibalism among them points out that the predatory behaviour has not completely disappeared. Adult St.virei can be fed with Cerophyl. Some observations on the burrowing activity and on the reactions to light, temperature and salt water have been made. All postmarsupial molts of Stenasellus occur in two steps (isopodian molts). The intramolt is extremely long (from 83 h 30 mi for the first molt of the free young), to 8-12 days, for the adult male and female, 14 days for female reproductive molts and 16-21 days for the molts of aged or senile individuals). The intermolts last from 2 1/2 months (first intermolt of the free young), to 9-12 months (non-reproductive ones of the adult) and 12-18 months (average: 15-16), for reproductive 9 intermolts. The normal lifespan of karstic subspecies of St.virei and related species must be estimated as 12 years (males) and 15 years (females). All these values are 10-20 times longer than these of an epigean Asellid of the same size (Asellus aquaticus). The reproductive cycle has been studied. The adult female is larger than the male. There is no precopulatory pairing ("nuptial ride"d 6-7 years or more, fur the female. In the juvenile male, the morphogenesis of I and Il pleopods takes place normally on intermolts 4-9 and lasts 3 years or more. On intermolt 10, it seems that the male is able to mate.

Paleo-distribution of Macroderma gigas in the South West of Western Australia, 1975, Bridge, P. J.

A study of the distribution of Macroderma remains in the caves of the southwest of Western Australia has shown greater past bat concentrations than previously recorded and that the distribution of skeletal remains and guano piles indicates a series of expansions and contractions of the Macroderma range during the Holocene.

Adult Batrachuperus in a cave in Iran. A new species?, 1978, Clerguegazeau M. , Farcy J. P.
During a speleological exploration of a cave in Iran, a species of Urodele Hynobiidae was found. This Batrachian is either a new species of the genus Batrachuperus or an adult form of the species Batrachuperus persieus previously only described in its larval and juvenile forms. Certain observable differences suggest that it can be considered a new species. Observations on its feeding habits indicate that the presence of this periodic trogloxene in the cave is not "accidental", but that it remains there for a long period during its life cycle.

Uranium-Series Ages of Speleothem from Northwest England: Correlation with Quaternary Climate, 1983, Gascoyne M, Schwarcz Hp, Ford Dc,
Over 180 $^{230}$Th/$^{234}$U ages have been obtained for 87 speleothems from caves in the Craven district of northwest England. Periods of abundant speleothem growth, 0-13, 90-135 and 170 to > 350 ka, are correlated with interglacial isotope stages 1, 5 and 7-9 respectively. Periods of zero growth, 14-35 and 140-165 ka, are correlated with glacial stages 2 and 6 respectively. A prominent break in growth of one speleothem, dated at about 260 ka, may be correlated with glacial stage 8. Lower-frequency growth from 35 to 90 ka is correlated with stages 3 and 4. The results may also be related to the British Quaternary sequence within the range of $^{14}$C determinations, as follows: 0-13 ka. Flandrian plus late Devensian deglaciation; 14-35 ka, late Devensian glaciation; 35-45 ka. Upton Warren interstadial. Low but finite speleothem abundance during the period 45-90 ka correlates with the early Devensian and is in good agreement with evidence indicating the non-glacial, but tundra-like, climate over this period. The Ipswichian interglacial is broadly related to the abundant growth period 90-135 ka, but is more closely defined by the interval 115-135 ka, from results of dating speleothems enclosing remains of Ipswichian fauna in one cave. By analogy with the zero speleothem abundance during the late Devensian glaciation, the period 140-165 ka may be tentatively correlated with the Wolstonian glaciation. Lack of direct stratigraphic relationships with, or absolute ages of, middle to early Pleistocene stages prevents further correlation of speleothem age data. From the frequency of abundance of speleothem basal ages for the period 0-13 ka, it appears that speleothem growth lags ice recession by up to 4 ka

Further Studies At The Blue Waterholes, Cooleman Plain, N.S.W., 1969-77, Part II, Water Chemistry And Discussion, 1983, Jennings, J. N.

The 1969-77 data confirm that groundwater temperature is significantly higher than air temperature at mean catchment altitude but provide only partial support for an explanation in terms of soil temperature and insulation of drainage from cold air ponding over the Plain. Higher pH of output than input streams is attributed mainly to percolation water chemistry. Water chemistry of two contrasted input streams suggests non-karst rock weathering has an important effect on allogenic input streams. An inverse relationship between carbonate hardness and output discharge is found again and attributed mainly to faster transit through the limestone at high flows. Summer has a steeper regression than winter due to precipitation and high flows depressing carbon dioxide and carbonate concentrations more in that season than in winter. Picknett graphs show how solutional capacity varies through the hydrologic system, with aggressive input streams, mainly saturated percolation water, and rarely saturated output springs because of the allogenic component in the last. The total carbonate load of Cave Creek is directly related to discharge, with little seasonal difference so the annual regression is chosen for later calculation. When the carbonate load duration curve and frequency classes for Cave Creek are compared with those for other karsts, it falls into an intermediate class in which neither very high nor low flows dominate the pattern. This is attributed to a combination of a large allogenic input with a complex routing pattern. Consideration of most input stream solute concentration on one occasion indicates such close dependence on catchment geology that doubt is cast on the smallness of the 1965-9 allocation of carbonate contribution from non-karst rock weathering to the allogenic input. This is explained by new CSIRO rainfall chemistry figures from the Yass R. catchment which are smaller than those used before and by elimination of a previous error in calculation. This time subtraction of atmospheric salts is done on a daily basis with a decaying hyperbolic function. Correction of Cave Creek output for allogenic stream input follows the method adopted in 1965-9 but on a firmer basis, with the assumption of approximately equal water yeild per unit area from the non-karst and karst parts of the catchment being more factually supported than before. It remains a substantial correction. The correction for subjacent karst input to Cave Creek is also improved by putting the calculation in part on a seasonal basis; it remains small. The exposed solute load output shows the same seasonal pattern as was determined earlier, with a winter/spring maximum, and it again evinced much variation from year to year. So did annual rates. The mean annual loss of 29 B was slightly greater than for 1965-9. If this difference is real and not an experimental error, the reduced allowance for atmospheric salts and greater annual rainfall in the second period could explain the increase. This erosion rate of 29 B from an annual runoff of about 400mm places this karst where it would be expected in the world pattern of similar determinations in terms of both runoff and its proximity to the soil covered/bare karst dichotomy of Atkinson and Smith (1976). Combined with the other work at Cooleman Plain on erosion at specific kinds of site, an estimate of the spatial distribution of the limestone solution is presented. It agrees well with the similar attempt for Mendip by Atkinson and Smith (1976), when allowance is made for certain differences in method and context. The main conclusions are the great role of solution in the superficial zone and the unimportance of the contribution from caves. Conflict between this process study and the geomorphic history of Cooleman Plain remains and once again an explanation is sought in long persistence of a Tertiary ironstone cover inhibiting surface solution.

Chronology of Guitarrero Cave, Peru, 1985, Lynch Thomas F. , Gillespie R. , Gowlett John A. J. , Hedges R. E. M. ,
Dating by accelerator mass spectrometry of wooden artifacts, cord, and charcoal samples from Guitarrero Cave, Peru, supports the antiquity of South America's earliest textiles and other perishable remains. The new dates are consistent with those obtained from disintegration counters and leave little doubt about the integrity of the lower Preceramic layers and their early cultivars. Reevaluation of the mode of deposition suggests that most of the remains resulted from short-term use of the cave in the eighth millennium B.C., with a possible brief human visit as early as 12,560 years ago

Les phnomnes karstiques des quartzites d'Afrique du Sud, 1987, Martini, J.
KARST FEATURES IN QUARTZITE OF SOUTH AFRICA - The author describes karst features developed in quartzite and also, but to a lesser extent, in weathered diabase and in wad. In quartzite, the karst is due to weathering along joints and bedding planes, producing softer areanaceous boundaries. Later, vadose caves form by piping in the weathered material, starting at a spring and progressing upstream. The karst features include dolines, swallow-holes, and caves, grouped in very localised systems. Over most of the quartzite plateaus, however, real karst features are absent and the drainage remains superficial. The only ubiquitous features, reminiscent of lapies, consist of pinnacles left after erosion of sand. As most of the time they are not associated to deep karst systems, the author proposes that they should not be considered as karst features. Other caves are developed in weathered diabase and dolomite (wad), sandwiched between resistant quartzite layers. They result from the erosion of these soft layers. The author is of the opinion that the term karst rather than pseudokarst should be used to describe this morphology developed in silica and silicate rocks. The reason is that not only the features produced compare well with the ones observed in " soluble rocks " (limestone, gypsum, etc.), but that the genetical process is very similar. It is suggested that the term pseudokarst should be used only in cases were the genesis is different.

Cave dams of the Guanyan System, Guangxi, China, 1987, Smart P. L. , Waltham A. C. ,
With well over 1 million km2 of carbonate rocks exposed at the surface, and a history of exploitation spanning in excess of 2000 years, the Chinese probably have more experience than any other people in developing the water resources of carbonate aquifers. Interestingly, many of the smaller scale projects are carried out by local farmers and co-operatives, with little recourse to the advice of professional engineers and hydrologists, although even in large regional schemes, much local expertise and labour is involved (see for example Hegtkcar 1976). While recently some of the Chinese work on karst hydrology has become available in the west (Song 1981; Song et al 1983; Yuan 1981, ) much of the practical experience resulting from these local and small scale developments remains unpublished even in China. We were therefore very fortunate to be able to examine the engineering works associated with the Guanyan cave system, just south of Guilin, Guangxi Province, SE China, during a recent joint venture with the Institute of Karst Research, Ministry of Geology, Guilin. The Guanyan (Crown Cave) system is developed in a sequence of relatively pure, predominantly finegrained limestones and dolomites over 2600 m thick, and ranging from Devonian to Carboniferous in age (Yuan 1980). These are folded into thrust faulted, NW-SE-trending folds, but dips are generally less than 30{degrees}. The underlying impermeable shales, siltstones and sandstones form a mountainous terrain rising to 1400 m above sea-level east of the limestone, and provide the headwaters for streams feeding into the caves (Fig. ...

Impact des proprits hydrodynamiques du substrat karstique sur la nature du sol en milieu mditerranen, 1989, Verheye, W. H.
The impact of the hydrodynamic properties of the karst substratum over the soil characteristic in mediterranean areas - The weathering and pedogenetic evolution on limestones in mediterranean areas leads to the formation of a more or less decarbonated red soil. This evolution passes through successive stages of decarbonatation, rubification and decalcification and can be associated with a colour change, which includes lithochromic, brown and red phases. It is obviously influenced by the hydrodynamic properties of the soils and by the underground drainage characteristics of the substratum: hence soils developed over almost impermeable marly limestones remain at the lithochromic and/or brown levels, and decarbonatation remains weak; on hard and fractured limestones, pedogenesis is much more active and, even if the weathering volume on this rather pure rocks is small, the soil profile becomes almost completely devoid of free lime; under certain conditions a slight decalcification of the soil sorption complex may even be observed.

Radon concentrations range from < 185 to 3,515 Bq m-3 throughout Lechuguilla Cave, Carlsbad Caverns National Park, New Mexico. Concentrations in the entrance passages and areas immediately adjacent to these passages are controlled by outside air temperature and barometric pressure, similar to other Type 2 caves. Most of the cave is developed in three geographic branches beneath the entrance passages; these areas maintain Rn levels independent of surface effects, an indication that Rn levels in deep, complex caves or mines cannot be simply estimated by outside atmospheric parameters. These deeper, more isolated areas are subject to convective ventilation driven by temperature differences along the 477-m vertical extent of the cave. Radon concentrations are used to delineate six microclimate zones (air circulation cells) throughout the cave in conjunction with observed airflow data. Suspected surface connections contribute fresh air to remote cave areas demonstrated by anomalous Rn lows surrounded by higher values, the presence of mammalian skeletal remains, CO2 concentrations and temperatures lower than the cave mean, and associated surficial karst features

Analyses and interpretation of an industrial multi-channel seismic grid, a 2.3 km-deep industrial well (NMA-1) and two ODP (Sites 715 and 716), have generated new insights into the evolution of the Maldives carbonate system, Equatorial Indian Ocean. The present physiography of the Maldives Archipelago, a double chain of atolls delineating an internal basin, corresponds only to the latest phase of a long and dynamic evolution, far more complex than the simple vertical build-up of reef caps on top of thermally subsiding volcanic edifices. Through the Cenozoic evolution of the Maldives carbonate system, distinct phases of vertical growth (aggradation), exposure, regional or local drowning, and recovery of the shallow banks by lateral growth (progradation) have been recognized. The volcanic basement underlying the Maldives Archipelago is interpreted to be part of a volcanic ridge generated by the northern drift of the Indian plate on top of the hotspot of the island of Reunion. The volcanic basement recovered at well NMA-1 and ODP Site 715 has been radiometrically dated as 57.2 1.8 Ma (late Paleocene) by 40Ar-39Ar. Seismic and magnetic data indicate that this volcanic basement has been affected by a series of NNE-SSW trending subvertical faults, possibly associated with an early Eocene strike-slip motion along an old transform zone. The structural topography of the volcanic basement apprears to have dictated the initial geometry of the Eocene and early Oligocene Maldives carbonate system. Biostratigraphic analyses of samples, recovered by drilling in Site 715 and exploration well NMA-1, show that the Maldives shallow carbonate system was initiated during the early Eocene on top of what were originally subaerial volcanic edifices. The Eocene shallow carbonate sequence, directly overlying the volcanic basement at NMA-1, is dolomitized and remains neritic in nature, suggesting low subsidence rates until the early Oligocene. During this first phase of the Maldives carbonate system evolution, shallow carbonate facies aggraded on top of basement highs and thick deep-water periplatform sediments were deposited in some central seaways, precursors of the current wider internal basins. In the middle Oligocene, a plate reorganization of the equatorial Indian Ocean resulted in the segmentation of the hotspot trace and the spreading of the Maldives away from the transform zone. This plate reorganization resulted in increasing subsidence rates at NMA-1, interpreted to be associated with thermal cooling of the volcanic basement underlying the Maldives carbonate system. This middle Oligocene event also coincides with a regional irregular topographic surface, considered to represent a karst surface produced by a major low-stand. Deep-water carbonate facies, as seen in cuttings from NMA-1, overlie the shallow-water facies beneath the karst surface which can, therefore, be interpreted as a drowning unconformity. In the late Oligocene, following this regional deepening event, one single central basin developed, wider than its Eocene counterparts, and the current intraplatform basin was established. Since the early to middle Miocene, the shallow carbonate facies underwent a stage of local recovery by progradation of neritic environments towards the central basin. The simultaneous onset in the early middle Miocene of the monsoonal wind regime may explain the development of bidirectional slope progradations in the Maldives. During the late Miocene and the early Pliocene, several carbonate banks were locally drowned, whereas others (i.e. Male atoll) display well-developed lateral growth through margin progradations during the same interval. Differential carbonate productivity among the atolls could explain these diverse bank responses. High-frequency glacialeustatic sea-level fluctuations in the late Pliocene and Pleistocene resulted in periodic intervals of bank exposure and flooding, and developed the present-day physiography of atolls, with numerous faros along their rims and within their lagoons
