Present-Day Cave Beetle Fauna in Australia A Pointer to Past Climatic Change, 1965, Moore, B. P.

Beetles form an important element of life in caves, where they provide some of the most spectacular examples of adaptation to the environment. The troglobic forms are of greatest interest from the zoogeographical point of view and their present distributions, which are largely limited to the temperate regions of the world, appear to have been determined by the glaciations and later climatic changes of the Quaternary. Troglophiles, which are much more widespread, show little adaptation and are almost certainly recently evolved cavernicoles.

Cockroaches (Blattodea) From Australian Caves, 1967, Richards, Aola M.

Ten species of Australian cockroaches are recorded from Australian caves and mines. Most are troglophiles or guanobia. Only one troglobitic species is known. The distribution of these species is given, and attention is drawn to their absence from south-eastern Australia and Tasmania. It is suggested that climatic changes in the Pleistocene and early Recent may have been responsible for this, and that the fauna found in many cave areas may be of comparatively recent origin.

Continental Pleistocene Climatic Variations from Speleothem Age and Isotopic Data, 1974, Thompson Peter, Schwarcz Henry P. , Ford Derek C. ,
Speleothems from continental North American caves have been dated by means of the 230Th/234U method. Oxygen isotopic variations in the dated samples and phases of speleothem deposition can be interpreted in terms of climatic change. A glacial chronology constructed from the age and isotopic data lends support to the astronomical theory of climatic change

Messinian event in the black sea, 1979, Hsu Kenneth J. , Giovanoli Federico,
Three holes were drilled during the 1975 DSDP Leg 42B drilling the Black Sea. A section from Hole 380, at 2107 m water depth on the western edge of the abyssal plain, is 1074 m thick, and provides the most complete stratigraphic section. Dating of the sediments is based upon (1) fossil evidence from pollen, crustaceans, benthic foraminifera, and diatoms, (2) correlation with climatic changes and with unusual isochronous events that have been dated elsewhere, (3) paleomagnetic data, and (4) estimates of sedimentation rate.The history of Black Sea sedimentation recorded by the DSDP cores includes black shale sedimentation during the Late Miocene, followed by periodic chemical sedimentation from Late Miocene to Early Quaternary, and a change to dominantly terrigenous sedimentation from the Middle Quaternary. These hemipelagic and turbiditic sediments were deposited in lacustrine and brackish marine environments. The Messinian sediments, however, consist of stromatolitic dolomite, oolitic sands, and coarse gravels, deposited in supratidal and intertidal environments. The intercalation of the shallow-water sediments in a deep-water sequence suggests a drastic lowering of the water-level within the Black Sea basin during the Messinian so that the edge of the present abyssal plain was then the edge of a shallow lake.The Messinian draw-down phase of the Black Sea was in existence for about 100,000 years during the Lago-Mare stage of the salinity crisis. The evaporated waters formed an alkaline lake before it was drowned by a brackish marine transgression correlative to the Trubi transgression of the Mediterranean

Climatic Change and the Evolution of Cave Invertebrates in the Grand Canyon, Arizona, 1980, Peck, Stewart B.

Glaciation and Karst in Tasmania: Review and Speculations, 1982, Goede Albert , Harmon Russell, Kiernan Kevin

The evolution of Tasmanian karsts is fundamentally interwoven with the history of Quaternary climatic change. Specifically karstic processes were periodically overwhelmed by the influence of cold climate which exerted strong controls over thermal, hydrological and clastic regimes. While these episodes of cold climatic conditions have temporally dominated the Quaternary, their legacy may be under represented in present karst landforms. There is no general case with respect to the consequences for karst of the superimposition or close proximity of glacial ice. The pattern of events in each area will be dependant upon the interaction between local and zonal factors. A number of Tasmanian karst which may have been influenced by glaciation are briefly discussed.

Une morphologie karstique typique en zone intertropicale : les karsts du Bas Zare, 1985, Quinif, Y.
A TYPICAL MORPHOLOGY OF TROPICAL KARSTS: THE KWILU BASIN IN THE LOWER-ZAIRE - The Kwilu basin, in the region of Bas-Zaire, shows typical landscapes of tropical karsts: cone and tower karsts shaped in precambrian limestones of the "Groupe schisto-calcaire". These precambrian series are little tectonised. They are covered with cenozoic formations which are important in the evolution of the karst. Different types of cavities are studied and replaced in the morphostructural context: old caves, originating in phreatic zone and now cut by the erosion, river streams in tunnel-caves, network under the water table. The superficial forms are interpreted as successive evolutive steps: dissection of a surface (morphological or structural) by a dendritic hydrographic network, birth of a cone-karst being transformed in tower-karst overlooking a new surface. We insist on the morphogenetic importance of the paleoclimatic changes and on the existence of an intertropical karstic morphology in stable craton.

Quelques aspects du karst en Chine, 1985, Tricart, J.
Some characteristic features of karst in China Karst terrain is widespread in China: some 2,000,000km2, corresponding to 20-25% of the whole surface of the country. It occurs at very different altitudes and under quite different climates, from the region of Zhoukoudian, where has been found the skull of the Pekin Man, to the Tibet Plateau, where there is presently permafrost conditions, and up to southern tropical moist China, near Canton and Guilin. Recent chinese investigations have proved that most karst features are old. In Southern China a tropical karst (tower-karst or "mogotes" karst) is associated with lacustrine deposits containing the well-known Hipparion Fauna, of Miocene age. Its predates the intensive uplift of the Himalaya and of the Tibet, which has begun during the Pliocene and has continued during all the Pleistocene. The same fossils have been found in this tropical karst in present permafrost areas, above 5,000m. In the region of Guilin (Guangxi Province), this tropical karst has been described. There is evidence for the former existence of a covered karst, where limestones and dolomitic limestones were covered by a thick layer of reddish residual clays, with limonite. This mantle has been stripped during different periods of drier and probably cooler climate, has suggested by pollen spectra. In some places, these residual products have been trapped into pits, cracks, and caves. We have observed a small quantity of red clay painting limestone stalactites and sinters (Chuanshan and Leng Yin Yen Caves, in the surroundings of Guilin). They present sometimes a mining interest and some extractive industries are presently active (limonite, cassierite, etc.). Many caves have been surveyed by the Institute of Karst geology, in Guilin. Some have been equiped for tourism, around Guilin. All these caves are old. Some radiocarbon dating of speleothems yield ages of 33,000 year BP. The famous carving of the Leng Yen Cave have not been affected by calcite deposition from dripping since at least 500 years. The large caves that have been surveyed should correspond to a long evolution span. Along the Lijiang River, at least two terraces can be observed. They are built with gravels and pebbles, covered with thinner sand and loam, suggesting climatic changes, also attested by the changes of fauna and vegetation. These past cooler periods are characterised by an opened vegetation, with the striping of the old weathering cover of the former tropical karst. These karst terrains have been investigated in China for management purposes. Groundwater oscillations have frequently resulted in land subsidences damaging buildings, and in dramatic collapses destroying fields, roads. Sometimes, underground collapse plugged caves and dammed underground rivers, resulting in floodings. The caves are frequently used as reservoirs for irrigation and power plants.

The Lower Mississippian Mission Canyon Formation of central to southwestern Montana was deposited under dominantly semiarid to arid climatic conditions during Osagean to early Meramecian times. Following deposition, a pronounced climatic shift to more humid conditions occurred during middle Meramecian times. This climatic change is indicated by extensive, post-depositional karst fabrics and in the stable isotopic composition of early, meteoric calcite cements and diagenetically altered sediments. Early meteoric calcite cement in Mission Canyon limestones is generally nonluminescent and fills intergranular and fenestral porosity. Petrographic data indicate that this cement formed during intermittent subaerial exposure of the Mission Canyon platform during Osagean times. This initial generation of meteoric calcite cement has deltaO-18 values from -8.1 to -2.6 parts per thousand PDB. These data, and the oxygen isotopic values from nonluminescent skeletal grains and micrite in host limestone indicate that Osagean meteoric water may have had deltaO-18 values as low as -6.0 parts per thousand SMOW. A second generation of petrographically similar, but isotopically distinct, calcite cement fills biomolds and porosity within solution-collapse breccias in the Mission Canyon Formation. This cement generation postdates earlier nonluminescent Osagean calcite cement and is volumetrically most abundant near the top of the Mission Canyon Formation. DeltaO-18 values from these cements and from nonluminescent lime mudstone clasts and matrix in solution collapse breccias range from -13.8 to -8.2 parts per thousand PDB. These data indicate that Meramecian meteoric water may have had deltaO-18 values as low as - 12.0 parts per thousand. However, a higher-temperature burial overprint on the deltaO-18 values of the calcite cement cannot be ruled out. The more positive deltaO-18 values of the Osagean calcite components probably indicate warm and arid conditions during short-term [10(4)(?) yr) subaerial exposure along intraformational sequence and parasequence boundaries. The more negative deltaO-18 values from Meramecian calcite components and the extensive karst associated with the post-Mission Canyon unconformity may have developed because of cooler and more humid climatic conditions and possible rain-out effects during middle Meramecian times. A dramatic shift towards cooler and more humid climatic conditions may be coincident with the onset of major continental glaciation in the Early Carboniferous. The post-Mission Canyon unconformity has been attributed to a major fall in sea level that may have glacio-eustatic origins. Growth of continental glaciers during a time of global cooling would have caused migration of polar fronts further toward the paleoequator. These polar fronts in turn, would have pushed moist, mid-latitude weather systems toward the paleoequator, resulting in cooler, more humid conditions in low-latitude settings during ''icehouse'' times

Observations morphologiques sur le gosystme karstique du Rupt du Puits (Meuse, Lorraine), 1995, Jaillet S. , Gamez P.
The karst system of Rupt-du-Puits is situated east of the Paris basin (Barrois and Perthois), in the Portlandian limestones covered by sands and clays of Lower Cretaceous. It presents 21 km of surveyed passages in several networks (catchment = 13 km2). In this typical covered karst (cryptokarst), we observe two kinds of alimentation: rapid (swallow holes) and slow (wet soils). On the exokarst, the valleys move by retreat of swallow holes and karst stepping. In the endokarst, the variations of the base level determine several stages of stream piracy (elbows of capture). The karst morphology depends on climatic changes and the evolution of the drainage pattern during the Upper Pleistocene.

Symposium Abstract: Hypogenetic karst and climatic change in North-Eastern Brazil, 1996, Auler A. S.

The influence of climatic change on exposure surface development: a case study from the Late Dinantian of England and Wales, 1996, Vanstone Simon,
Exposure surfaces represent an integral part of Asbian-Brigantian cyclothemic platform carbonates in England and Wales. These are characterized by the association of clay palaeosols, calcrete and palaeokarst and in most instances would appear to have been polygenetic. Alternating calcrete-karst stratigraphies associated with individual exposure surfaces indicate that the climate changed from semi-arid to humid to semi-arid conditions during each sea-level fall/rise cycle. Lowstand intervals were humid and resulted in karstification of the cyclothem-top sediments and the formation of a mineral soil. In contrast, regressive/transgressive phases were semi-arid and resulted in calcretization of the emergent platform carbonates. The influence that climatic cyclicity had upon exposure surface development was modulated by variations in platform bathymetry, subsidence and spatial climatic variation, and platforms exhibit their own individual record of what was essentially an idealized sequence of events. As with the sea-level oscillations responsible for cyclothemic sedimentation, the climatic cyclicity is thought to be the product of orbital forcing and probably reflects either eccentricity-driven shifts in the locus of monsoonal precipitation, or precession-driven variations in monsoonal intensity. If precessional in origin, exposure surface development represents a single minimum to minimum excursion, some 20 ka in duration, whereas if eccentricity-driven this may have been appreciably longer. Nevertheless, the immature nature of the exposure surfaces suggests that emergence was probably only of the order of a few tens of thousands of years
