On mineralogy of karst cavities of the Crimean Piedmont: montmorillonite in grottoes of Kachi-Kaljon, 2013, Tishchenko A. I. , Tymokhina . .

Alteration of isotopic composition of wallrock of hypogene karst conduits in the Crimean Piedmont, 2013, Dublyansky Y. V. , Klimchouk A. B. , Tymokhina E. I. , Amelichev G. N. , Sptl C.

The paper presents the results of a systematic study of the oxygen and carbon isotopes in the walls of the hypogene karst conduits in the Crimean Piedmont, including conduits that are entirely open and represent the cuesta cliffs. Most of the studied cores reveal wide zones of weak isotopic alteration (tens of cm to several m; 1 to 3 ‰) and narrow zones of strong alteration (4 to 15 mm; up to 4-7 ‰) for both C and O. Interaction between carbonate bedrock and fluids is expected in relatively closed hydrogeological conditions characteristic of the hypogene speleogenesis. The most-altered rock has isotopic composition identical to that of the phreatic speleothems, found in some of the studied conduits. This suggests that the altering waters and mineral forming solutions are genetically related. Several alteration trends are apparent in the C-O isotope space, suggesting that the bedrock has experienced more than one stage of alteration, characterized by different physico-chemical parameters of fluids (including different sources and isotopic composition of carbon and, possibly, different temperatures).


Isotopically altered wallrock of the hypogene conduits in the Crimean Piedmont, Ukraine, 2013, Klimchouk A. , Dublyansky Y. , Tymokhina E. , Sptl Ch.

The Crimean Piedmont stretches along the tectonic suture separating the fold-and-thrust structure of the Crimean Mountains from the Scythian Plate. It comprises two cuesta-like ridges whose structural slopes are built up of homoclinal limestone beds of the Paleocene- Eocene (the Inner Range), and the Neogene (the Outer Range) ages. Abundant relicts of the hypogene karst have been identified recently in steep cuesta cliffs of the Piedmont. The hypogene cavities formed in confined to semi-confined hydrological conditions due to interaction of the deep-seated waters, ascending along cross-formational fracture conduits, with the strata-bound lateral filtration flow. The ongoing geomorphological dissection of the stratified structure of the Piedmont com-monly follows the pre-formed hypogene conduits, resulting in the development of the pronounced cuesta relief with steep cliffs featuring massive exposure of the hypogene karst conduit paleo-walls with specific morphologies.
Movement of deep-seated fluids through carbonate wallrock may cause isotopic altera-tion of the later. We have studied isotopic composition of C and O along nine cores drilled into the walls of the cliffs decorated with hypogene solutional features, as well as in two hypogene caves. Data from all cores show the presence of a wide isotopic altera-tion halo, whose thickness exceeds the core length (max. 40 cm). In this zone, the rock is slightly depleted in δ18 (ca. 1 -2 ‰) relative to the “pristine”, unchanged values of a given rock unit. In most cores the rock is also depleted in 13 but two cores show high-er 13C values. In addition to this low-gradient alteration, most of the cores also show a narrow (4-50 mm) zone of the high-gradient alteration, across which δ18 and δ13 drop by respectively, 2.0–4.9 ‰ and 0.7–4.5 ‰. At three localities, the walls of the hypogene cavities were coated with phreatic calcite. Isotopic composition of this calcite corresponds to the lowermost values of the altered rock. In one core, the rock in the high-gradient alteration zone is depleted in 18 but enriched in 13. In yet another core the rock is enriched in both 18 and 13. The results corroborate the hypogenic origin of conduits and suggest that the wallrock was exposed to, and interacted with, geo-chemically different waters after the main volume of cavities had been created by disso-lution.


The hypogene karst of the Crimean Piedmont and its geomorphological role (in Russian), 2013, Klimchouk A. B. Tymokhina E. I. Amelichev G. N. Dublyansky Y. V. Spö, Tl C.
The book offers a fundamental new interpretation of the origin of karst in the Crimean Piedmont and explains the role karstification played in the geomorphogenesis of the region. The hypogene origin of karst cavities, their leading role in dismembering the Crimean Piedmont’s homocline and the formation of the characteristic cuesta and rock-remnant relief of the area is demonstrated on the basis of a systematic and comprehensive study, which included modern isotopic and geochemical methods.
The hypogene karst in the area developed in conditions of the confined to semi-confined groundwater flow systems, via interaction between the ascending flow of the deep-seated fracture-karst (conduit) water and the strata-bound, predominantly porous aquifers of the layered formations in the homoclinal northern mega-slope of the Crimean Mountains. The major pre-requisites for hypogene karst development is a position of the area at the flank of the Prichernomorsky artesian basin, and in a geodynamically active suture zone, which separates the fold-thrust structure of the Crimea Mountains and the Scythian plate. Opening of the stratified structure of the Piedmont follows the near-vertical cross-formational fracture-karst channels, resulting in the development of the pronounced cuesta relief with steep cliffs, which feature massive exposure of channels with karst-affected morphology.
Hypogene karstification results in characteristic morphologies, including caves, cliff niches and open chambers, variously sculptured and honeycomb-cellular surfaces of limestone cliffs, wide and shallow couloirs near the rims of cuestas, and rock remnants-“sphinxes”. The carbonate bedrock in the walls of the hypogene cavities revealed isotopic alteration (both O and C) caused by the action of hypogene fluids. The time of formation of cuestas in the Inner Range of the Crimean Mountains, determined on the basis of the U-Th disequilibrium dating of speleothems, turned out to be younger than thought previously. The active development of hypogene karst in the geologically recent past was the main factor responsible for today’s geomorphologic peculiarity of the Crimean Piedmont.
The book will be of interest for karstologists, hydrogeologists, geomorphologists, geologists, and environmental scientists studying karst regions, ore geology and carbonate reservoirs of hydrocarbons. It will also be useful for students of the respective disciplines, and for all those interested in the nature of the Crimean Piedmont.
