Geochemistry of Regional Groundwater Flow in the Aladag Karstic Aquifer, Eastern Taurids-Turkey: Effect of Flow Conditions, 1995, Bayari C. Serdar, Kurttas Turker
The geochemistry of regional groundwater flow along the Aladag karstic aquifer indicates a remarkable correlation between the hydraulic and geochemical conditions. The Aladag. karstic aquifer, in between the recharge area and the regional erosion base, comprises unconfined and confined sections. A transition zone along which semi-confined flow conditions dominate also occurs between these sections. The parts of the aquifer in which unconfined and confined flow conditions dominate seem to be analogous of geochemically open and closed systems of carbonate dissolution, respectively. The varition of physical and chemical properties of the karstic effluents implies that although the carbonate dissolution is perpetual along the flow system, dissolution rates decrease where confined flow conditions start to prevail. However, gypsum dissolution along the regional flow path seems to be independent of hydraulic conditions.

Combined use of environmental isotopic and hydrochemical data in differentiation of groundwater flow patterns through the Aladağ karstic aquifer-Turkey, Application of Tracers in Arid zone Hydro, 1995, Bayari C. S. , Gunay G.
Distinction between the different groundwater flow systems in karstic areas constitutes one of the major objetives of the basin-wide hydrogeologic research. Use of environmental isotopic and hydrochemical investigation techniques provide a great deal of information for the identification of regional groundwater flow systems. The Lower Zamantı Basin, located in the eastern Taurids, presents an accountable water resource potential that can be used for hydroelectric power production. The basin, with the elevation range between 400 m and 350 m, occupies a catchment area of 2000 km2. Humid and semi-arid climatic regimes prevail in the southern and northern parts of the basin. The carbonate rocks and the overlaying impervious ophiolite nappe constitute the major geologic units in the area. Systematic hydrochemical and environmental isotopic surveys have been carried out to discriminate between the different groundwater flow systems existing in the basin. Hydrochemical studies have been conducted by insitu measurements, sampling and analyses of water samples from about 80 points. Based on the results of hydrochemical evaluations, 23 sampling points, including streams and karstic springs, have been selected for environmental isotopic survey. The integrated evaluation of the available data indicates clearly that two different groundwater flow patterns exist in the basin; namely a shallow flow and a deep regional flow. The characteristic values of temperature, electrical conductivity, carbonate alkalinity and log PCO2 of the shallow-flow in the karstic effluents fed by shallow groundwater circulation springs are 8C, 80 S/cm, 1.5 meq/l and 10-2 atm, respectively. On the other hand, higher values, such as 15C, 455 S/cm, 5.0 meq/l and 10-1 atm are observed in the springs fed by deep-regional groundwater flow. The tritium data indicate that the springs fed by the deep-regional groundwater have longer residence times. Moreover, the recharge area elevations, as envisaged from the oxygen-18 data, also provide supporting evidence for the distinction of different groundwater flow patterns. Additionally, comparison of groundwater temperature with oxygen-18 content presents reliable information to understand the possible interaction among the different karstic effluents.

Travertines are terrestrial, fresh water carbonate deposits formed by karstic springs and associated streams which are saturated with respect to calcite. Field observations form recently travertine depositing arstic springs in Aladağlar, Eastern Taurids ? Turkey indicate that the deposition process is accelerated considerably by the physical and biochemical contribution of algae which are mostly belong to classes of Cyanophyceae (blue-green algae) Chlorophyceae (diatoms), Eugleno-phyceae and Xhantophyceae. Algae conributes physically to the deposition of travertine by means of trapping of inorganically formed calcite micro-crystals by algal filaments and mucilagenous secretions and by providing proper nucleation sites for calcite precipitation. Biochemical activity of algae also forces the aquatic system to deposit travertine due to the photosynthetic removal of free carbondioxide from the solution. Field observations indicate that the rate of physical and chemical contribution to the deposition depends strongly on the hydraullic conditions. Physical and biochemical roles becomes important in high and low /velocity/energy streams, respectively. The effect of algal association over the travertine deposition can be observed apparently especially in streams where the ratio of algal mass to the rate of stream flow is substantially high. Since the climatic conditions (air temperature and insolation) have strong influence upon the abundance of algae, the rate of travertine deposited by algal contribution decreasing during winter months when algal population decreases. Similarly , the biochemical contribution shows a diurnal pattern with a maximum during a mid day because of the higher uptake of carbondioxide via photosynthesis.

Glacial destruction of cave systems in high mountains, with a special reference to the Aladaglar massif, Central Taurus, Turkey, 2006, Klimchouk A. Bayari S. Nazik L. TÖ, Rk K.

Erasure of karst features and dissection of karst are among the main destructive effects of glacial action upon karst (Ford, 1983). They lead to destruction of functional relationship between the relief and a karst system, and to glacial dissection of pre-glacial cave systems. Stripping of the epikarstic zone and upper parts of cave systems on sub-horizontal surfaces results in prevalence of decapitated shafts in high mountains affected by glaciations. Vertical dissection of a karst massif by glacial erosion creates cave openings in sub-vertical surfaces (cliffs), a well known feature. Observations of vertical shafts exposed by cliffs are less common. Such shafts, unwalled by surface geomorphic processes, are in a certain way an analogous to the “unroofed” caves, exposed by denudational lowering of sub-horizontal surfaces. The Aladaglar Massif (Central Taurus, Turkey) is an outstanding example of high mountain karst. The high-altitude part of the massif has been severely glaciated during quaternary. Glacial erosion was the dominant factor in the overall surface morphology development, resulting in the formation of numerous glacial valleys, cirques, ridges and pyramidal (horn) peaks. The overall relief between the highest peaks and the lowest karst springs in Aladaglar is 3350 m. The local vertical magnitude of relief between bottoms of glacial valleys and surrounding ridges is up to 1700 m. Recent studies suggest that the most recent major glaciation occurred in the Aladaglar massif during the Holocene Cooling and terminated between 9,300 and 8,300 years BP. This paper describes unwalled shafts at subvertical surfaces, a feature which is common in Aladaglar but is not so common, or overlooked, in other high mountain areas. Exposure of such shafts is mainly due to intense gravitational processes induced by the combined effect of the removal of the ice support to cliffs and the glacial rebound.

Quaternary glaciations of Turkey, 2011, Sarikaya M. A. , Ciner A. , Zreda M.

The cosmogenic exposure ages obtained from glacial landforms in several Turkish mountains provided a basis to reconstruct glacio-chronology and paleoclimate of Turkey. Glacier-related landforms occur in three major regions of Turkey; (1) the Taurus Mountains, along the Mediterranean coast and southeast Turkey, (2) mountain ranges along the Eastern Black Sea Region, and (3) volcanoes and independent mountain chains scattered across the Anatolian Plateau. 10Be 26Al and 36Cl ages show that the oldest and most extensive mountain glaciers were developed during the Last Glacial Maximum. Unusual Early Holocene glaciations, dated to 9 ka-10 ka, were also reported from Mount Erciyes and Aladaglar.

ESR and 230h/234U dating of speleothems from Aladaglar Mountain Range (AMR) in Turkey , 2014, Ulusoya Ülkü, Anbara Gül, Bayarıb Serdar, Uysalc Tonguç

Electron spin resonance (ESR) and 230Th/234U ages of speleothem samples collected from karstic caves located around 3000 m elevation in the Aladağlar Mountain Range (AMR), south-central Turkey, were determined in order to provide new insight and information regarding late Pleistocene climate. ESR ages were validated with the 230Th/234U ages of test samples. The ESR ages of 21 different layers of six speleothem samples were found to range mostly between about 59 and 4 ka, which cover the Marine Oxygen Isotope Stages (MIS) MIS 3 to MIS 1. Among all, only six layers appear to have deposited during MIS 8 and 5. Most of the samples dated were deposited during the late glacial stage (MIS 2). It appears that a cooler climate with a perennial and steady recharge was more conducive to speleothem development rather than a warmer climate with seasonal recharge in the AMR during the late Quaternary. This argument supports previous findings that suggest a two -fold increase in last glacial maximum mean precipitation in Turkey with respect to the present value.
