Tracing the origin of cave sands: State of the art in the Moravian Karst
Original language description
The analyses of translucent heavy minerals in cave sands has brought good results in provenance studies due to distinct composition of assemblages. In the case of Moravian Karst, Czech Republic, there are several specific “end members” controlled by surrounding rock complexes. Granitoids and respectively Devonian clastics at the western vicinity of Moravian karst limestone strip are rich in amphibole, epidote and zircons. The Northerly complex of lower Carboniferous flysh deposits (Culmian facies turbidites) has brought a mixture of epidotes and garnets. The Eastern neigbourhood flysh deposits has also been a source of garnets. Cretaceous paleokarst deposits have most important typomorphic minerals staurolite and kyanite. Miocene Ottnangian sands are almost always rich in staurolite. Finally, the Pleistocene loesses have a typical amphibole-garnet mixture. That is why the comparison and evaluation of translucent heavy mineral assemblages of allochthonous sands should serve in the caves of Moravian karst (and thus off course in many karst caves of the world) as a key to their source and/or their origin. Final task is to understand better the history of karst, or more often of the paleokarst processes.
