Age Dating of Karst Forms Upon Regional Assessment of Karst Hazard (A Case Study of the Tatarstan Republic, Russia)
V. A. Yolkin, Institute of Environmental Geoscience, Russian Academy of Sciences
ABSTRACT:
The detailed investigations accompanied by collection of forty samples for radiocarbon and palynological analyses from six poorly and well-marked in a relief karst and karst-suffosion sinkholes, have shown, that the largest of them (diameter more than 30 m) are up to 5 - 10 thousand years, and the smaller size up to 2 - 3 thousand years. The marked karst forms - lakes, hollows and the depression reaching in diameter 200 - 300 m and more, were formed due to merging of separate forms and, most likely, have a long pre-Holocene history. The general procedure of regional probabilistic-deterministic assessment of karst hazard with karst collapse (sinkhole) intensity (cases of failures / km2 · years; m2/ km2· years) is discussed. Example is provided of corresponding map of karst hazard, made for the typical karst area of Tatarstan Republic.
