Paleoclimate and location of the border between Mediterranean climate region and the Saharo-Arabian Desert as revealed by speleothems from the northern Negev Desert, Israel, , Vaks A. , Barmatthews M. , Ayalon A. , Matthews A. , Frumkin A. , Dayan U. , Halicz L. , Mogilabin A. , Schilman B. ,
Speleothem bearing karstic caves of the northern Negev Desert, southern Israel, provides an ideal site for reconstructing the paleoclimate and paleo-location of the border between Mediterranean climate region and the Saharo-Arabian Desert. Major periods of speleothem deposition (representing humid periods) were determined by high resolution 230Th-U dating and corresponding studies of stable isotope composition were used to identify the source of rainfall during humid periods and the vegetation type. Major humid intervals occurred during glacials at 190-150[no-break space]ka, 76-25[no-break space]ka, 23-13[no-break space]ka and interglacials at 200-190[no-break space]ka, 137-123[no-break space]ka and 84-77[no-break space]ka. The dominant rainfall source was the Eastern Mediterranean Sea, with a possible small contribution from southern tropical sources during the interglacial periods. When the interglacial interval rainfall was of Eastern Mediterranean origin, the minimum annual rainfall was ~ 300-350[no-break space]mm; approximately twice than of the present-day. Lower minimum amounts of precipitation could have occurred during glacial periods, due to the cooler temperatures and reduced evaporation. Although during most of the humid periods the vegetation remained steppe with mixed C3 C4 vegetation, Mediterranean C3 type steppe-forest vegetation invaded southward for short periods, and the climate in the northern Negev became closer to Mediterranean type than at present. The climate was similar to present, or even more arid, during intervals when speleothem deposition did not occur: 150-144[no-break space]ka, 141-140[no-break space]ka, 117-96[no-break space]ka, 92-85[no-break space]ka, 25-23[no-break space]ka, and 13[no-break space]ka-present-day.Precipitation increase occurred in the northern Negev during the interglacial monsoonal intensity maxima at 198[no-break space]ka, 127[no-break space]ka, 83[no-break space]ka and glacial monsoonal maxima at 176[no-break space]ka, 151[no-break space]ka, 61[no-break space]ka and 33[no-break space]ka. However, during interglacial monsoonal maxima at 105[no-break space]ka and 11[no-break space]ka, the northern Negev was arid whereas during glacial monsoonal minima it was usually humid. This implies that there is not always synchroneity between monsoonal activity and humidity in the region.Oxygen isotopic values of the northern Negev speleothems are systematically lower than contemporaneous speleothems of central and northern Israel. This part is attributed to the increased rainout of the heavy isotopes by Rayleigh fractionation processes, possibly due to the farther distance from the Mediterranean coast

The article gives an account of the biological works carried out in the caves and other subterranean habitats of Israe1. The botanical and zoological investigations are summarized separately and a list of literature dealing with biospeleological research in Israel is supplied.

Two new Halacariens of Israel Limnohalacarus capernaumi n. sp. And Lohmannella heptapegoni n. sp., 1967, Petrova Anelya
Two new species of Halacarinae of a thermal slightly brackish spring near the Tiberiade lake in Israel are reported. Limnohalacaras capernaumi n. sp. Has certain characteristics typical of other species of the Genus, but is clearly distinguished by proper elements. Lohmannell heptapegoni n. sp. resembles Lohmannella stammeri Viets, of which it is distinguished by the structure of the dorsal plates, the palp and the morphology of the genital apparatus.

Karst processes of the eastern upper Galilee, Northern Israel, 1974, Gerson R,
Karst processes dominate most of the geomorphic activity in the Upper Galilee, consisting mainly of dolomites and limestones. Study of the chemical evolution of water passing through the karst hydrologic cycle clearly shows that the major portion of its carbonate solute is gained subaerially and in the upper part of the vadose zone. Most cave and spring water is already saturated with respect to aragonite and calcite.The karst depressions typical to surface morphology are mostly associated with fault-line traces. Their evolution is possible mainly in areas sloping initially less that 5[deg].The absence of evolved caves, representing well-developed karst of an earlier period, is attributed mainly to the marginal climate throughout the past combined with tectonic, and hence hydrologic, instability of the region.The discharge of the karst prings shows clearly dependence on annual precipitation, with a lag of about 2 years of the response to drought or more humid periods. Long-term fluctuations are larger in the smaller T'eo Spring than in the affluent 'Enan Springs.Most of the denuded material is extracted from the region as dissolved load via underground conduits and only small amounts as clastics. Mean long-term denudation is approximately 20 mm/1000 years, averaged for the surface area contributing to the springs.In spite of the above, most topographic forms are shaped by runoff erosion, active during medium to high intensity rainstorms. Solution processes prevail during low to medium rainfall intensities, while different parts of the region are denuded at similar rates. Even in karst depressions, erosion becomes dominant after their bottoms are covered by almost impervious terra-rossa mantle

Grottes de lave et volcano-karst de surface dans la rgion basaltique du Golan (lsral), 1984, Inbar, M.
Lava caves and surface volcano-karst features in the basaltic area of the Golan Heights (Isral) - Caves are formed endogenically as lava tubes and exogenically by erosion of the interlayer lava flows; calcitic speleothems are found in the basaltic caves. Surface depressions may have been formed by collapsed caves or by volcanic explosions. The drainage density is low and surface morphology locally resembles karst karren fields.

Sr isotope study of vein and cave calcites from southern Israel, 1990, Avigour A, Magaritz M, Issar A, Dodson Mh,
The strontium isotope compositions of secondary calcites from the Negev, southern Israel, were compared to those of the marine carbonate host rocks, which range in age from Triassic to Eocene, in order to understand fluid source and migration through fracture systems in dominantly carbonate strata. The Sr isotopes of these calcite clusters are divided into two groups: (1) calcites with 87Sr/86Sr values greater than those of the host carbonates; and (2) calcites with 87Sr/86Sr values close to the values of the host carbonate. 1. (1) These secondary calcites were found on the main tectonic lines of the Negev (faults and fold axes) and are enriched in 87Sr (87Sr/86Sr = 0.707709-0.709151) relative to the marine carbonate country rocks (87Sr/86Sr = 0.707251-0.70755, with one exception). These calcites are associated or crossed by thin veins filled by Fe- and Mn-oxides.2. (2) Secondary calcites with 87Sr/86Sr values close to those of the marine carbonate country rocks (0.7073-0.7077) are found in karstic caves and veins, and are located in sites which are not on the major faults and fold axes. These calcites are not crossed by Fe- and Mn-oxides.The isotopic results indicate that the solutions from which the secondary minerals of the first group precipitated were not in isotopic equilibrium with the marine host rocks. The possible source of the precipitating solutions can be either surface rain descending through the fault system or ascending groundwaters from the deep Nubian aquifer (Paleozoic to Early Cretaceous in age). In both cases there would be a limited interaction with the host sandstone rock which usually is depleted in Sr. The similarity of the 87Sr/86Sr values to those of the host rocks in the second group suggests that the main source of Sr in these calcite crystals was from the dissolution of the marine carbonate country rocks by rain- and flood waters

Karst origin of the upper erosion surface in the Northern Judean Mountains, Israel, 1993, Frumkin, A.
The upper erosion surface in the northern Judean Mountains is actively karstified, in the vadose zone and on the surface. The karst valleys become gradually covered with Terra Rossa which inhibits further denudation underneath the impermeable cover. Higher solution rates in the elevated areas keep the erosion surface relatively flat. The main characteristics of the area which dominate karst processes are fissured carbonate rocks with some insolubles and aeolian contribution, non arid climate and moderate relief. The erosion surface developed probably since the Oligocene regression. The Pleistocene uplift of the mountain backbone increased the relief and reduced the area of the karst plateau.

Hydrology and denudation rates of halite karst, 1994, Frumkin A,
Salt karst terrains exist mainly in arid climates where rock salt outcrops may escape complete destruction by dissolution. Such is the case with Mount Sedom, on the SW shore of the Dead Sea, one of the most arid parts of Israel. Many small catchments developed over the relatively insoluble cap rock which overlies the highly soluble rock salt. The catchments were surveyed and classified. Some 57% of the surface area is drained by an underground karst system. Water samples from various points in the system were analysed, and water development was inferred. Waters in cave conduits do not reach saturation during flood flow, unless the water is ponded for at least several hours. Based on the available evidence, regional karst denudation is tentatively estimated to be about 0.5-0.75 mm year-1, occurring mainly within the rock salt

Middle Holocene environmental change determined from the salt caves of Mount Sedom, Israel, 1994, Frumkin, A. , Carmi, I. , Zak, I. And Magaritz, M. , 1994
Paleoclimatic sequence for the Middle Holocene was constructed, based on Mount Sedom salt caves, and other evidence. Mount Sedom is a salt diapir, on the southwestern shore of the Dead Sea, which has been rising above the local base level throughout the Holocene. Allogenic karst development has kept pace with the rising, forming vadose caves. Wood fragments found embedded in flood sediments that were deposited in sub-horizontal cave passages yielded 14C ages from 7090 to 200 YBP. The paleoclimatic sequence is based on parameters that include: relative abundance of plant types or floral communities, the elevations of the corresponding relict cave passages and the ratio of their width to present passage width. Moister climatic stages are indicated by relatively abundant wood remains, by wide cave passages and by higher-level outlets, indicating high Dead Sea levels. Arid periods are marked by a scarcity of wood remains, by narrow cave passages and by low-level outlets. The results were correlated to other middle-Holocene evidence and temporal settlement changes. The Early Bronze period in Israel was the moistest period during the last 6000 years and as such it encouraged cultural development. It was followed by a considerable desiccation that caused a cultural deterioration.
