Isotopic indications of water-rock interaction in the hypogene Tavrskaya cave, Crimea, Ukraine, 2011, Dublyansky Yuri, Klimchouk Alexander, Timokhina Elisaveta, Spö, Tl Christoph

The Inner Range of the Crimea Mountains has recently been identified as an area of previously unrecognized hypogene speleogenesis (Klimchouk et al. 2009). The entrance of the Tavrskaya cave is located in the middle of the 25 m-high scarp of the cuesta built up of Paleocene limestone. The cave comprises two parallel major passages (ca. 180 m long, up to 7-8 m high and up to 5-6 m wide) connected by a smaller passage. The major passages are slightly inclined toward the north-west following the dip of bedding. The morphology of the cave bears strong indications of dissolution at conditions of ascending flow in a confined aquifer setting.
A massive calcite crust, studied in this paper, was first found in a small cave located ca. 200 m from Tavrskaya cave along the cuesta scarp. According to its position and morphology, the cave corresponds to the rift-like “feeder” zone of Tavrskaya cave. Recently, similar calcite crust was found in Tavrskaya cave, in a rift-like passage of the  near-scarp zone. The crust is built up of a brownish translucent calcite whose columnar crystals (bounded by competitive growth surfaces) are arranged in a characteristic radiating pattern. Calcite contains only all-liquid inclusions indicating deposition at less than ca. 50ºC. It also contains filamentous biological material (possibly fungi or cyanobacteria), which sometimes facilitated entrapment of fluid inclusions. This calcite body is tentatively
interpreted as a paleo-spring deposit (ascending flow). In order to characterize the isotopic properties of this calcite and the bedrock limestone we drilled small-diameter cores through the calcite formation, as well as through the wall of a cavity devoid of calcite. Stable isotope analyses were performed along these cores. To provide a basis for comparison several samples from the same lithostratigraphic units were collected far from the cave. Along a 15 cm-long profile, both oxygen and carbon isotopes of the limestone remain stable at 18O = -4.3 0.2
h and 13C = -1.7 0.3 h (1). Only within the 1.5 cm-thick zone immediately underlying the calcite 18O and 13C values plunge to ca. -8 h and -9 h respectively,. It appears from this data that water rock-interaction associated with the deposition of this calcite produced only a thin alteration halo in the limestone. However, when data from the cave-wall cores are compared with those collected far from the cave, it appears that the “constant” values from cave walls are shifted relative to the presumably unaltered limestone values toward lower values by
ca. 1.5-3.0 h (oxygen) and 3-4 h (carbon). On the 18O-13C cross-plot the data for unaltered limestone, cave wall limestone, alteration halo, and secondary calcite plot along a well-defined line (R2=0.99).
We propose that the Paleocene limestone in the vicinity of the Tavrskaya cave has experienced a two-stage alteration. During the first stage, presumably associated with the process of cave excavation, the bedrock has been altered (18O depleted by 1.5 to 3.0 h and 13C by 3 to 4 %). The thickness of this zone of early alteration is unknown but must be larger than 15 cm (length of our cores). The second stage of alteration was associated with the deposition of calcite; during this stage the isotopic composition was further depleted (by 4-5 h in 18O and 8-10 h in 13C). The extent of alteration was much smaller, though, and restricted to zones where calcite was deposited (ca. 15 mm beneath the calcite).


Morphogenetic analysis of Tavrskaya Cave (Inner Range of the Piedmont Crimea), 2011, Klimchouk, A. B. , Timokhina E. I.

In this paper, we refine the theoretic and methodological basis of speleomorphogenetic analysis and apply it to the Tavrskaya Cave in the Piedmont Range of Crimea, the largest cave in this region. Technique and results of the large-scale morphogenetic mapping of the cave are also presented.

Tavrskaya Cave is developed in the 20 m thick layer of Paleocene limestones of the Inner Range and is controlled by a fracture set of sub-latitudinal orientation that is well expressed in the entire Cretaceous-Paleocene succession and played an important part in the formation of river valleys and various lineaments. The cave structure in the plan view and many features of cave morphology are controlled by sub-vertical tectonic fractures and their intersections with a prominent permeable bedding plane in the middle of the sequence and a layer above it. The cave structure and morphology does not show any indications of epigene speleogenesis (specific pattern, functional/genetic relationships with the surface, vadose solutional modification in the contemporary settings, etc).

Composition of dissolutional speleoforms identified in the cave, their genetic interpretation and the analysis of their relationships, as well as some mineralogical evidence, unequivocally indicate the formation of the cave morphology in the conditions of a confined aquifer system with sluggish circulation, interaction of upwelling flow of a deep flow system with lateral flow in a shallow stratiform aquifer, with significant role of free convection. Relative to the contemporary hydrogeological settings, established in the area since the end of middle Pleistocene, the cave is relict. Vadose conditions on the level of main passages established not later than 130 ka as suggested by the maximum age of dated stalagmites.
