Paleokarst features and other climatic relics in Hungarian caves
Katalin Bolner-Takács - (28/1,1999)
Relics of climatic changes during the modern phase of karstic development have been preserved in the morphology, sediments and speleothems of several caves in Hungary, and there are examples of real paleokarst features exposed by modern caves as well. The unique sandstone morphology of Cserszegtomaj Well Cave (Keszthely Mts., Transdanubian Mountain Range), developed along the contact of Triassic dolomite and Pannonian sandstone, displays the relief of a karst surface formed probably under the subtropical conditions of the Early Miocene. The uppermost parts of Beremend Crystal Cave (Villány Mts., South Transdanubia) exposes also from below the clastic fill of an ancient karst shaft that, according to its rich vertebrate remains, dates back at least to the Lower Pleistocene. With their Late Eocene marine sediment fill, the small paleokarst cavities exposed in the Eocene bedrock of Mátyás-hegy and Pál-völgy Caves (Buda Hills) are interpreted as salt-fresh water mixing zone cavities formed during a short immersion of a tropical reef.
