KRASOVA JASKYNA PRYA V STIAVNICKYCH VRCHOCH - HYDROTERMALNA SPELEOGENEZA V KARBONATOVOM PODLOZI MIOCENNEHO STRATOVULKANU, 2011, Bella P. , Sucha V. , Gaal E. , Kodera P.

A cave of hydrothermal origin in crystalline limestone has been investigated near Sklene Teplice Spa in the Stiavnicke vrchy Mts. located in Central Slovakia. Metamorphozed Middle Triassic carbonate rocks occur as a horizon in pre-volcanic basement of Middle Miocene volcanic formations. The hydrothermal origin of studied cave is documented by spherical and irregural oval phreatic morphology sculptured by ascending thermal water, metamorphic type of the host rocks and their hydrothermal alteration, occurrence of large calcite and quartz crystals, and hydrothermal clays with three mineral smectite-kaolinite, illite and goethite associations. The primary phases of speleogenesis in the crystalline limestones was caused by hydrothermal processes linked either to the emplacement of granodiorite subvolcanic intrusions during the Late Badenian time or to epithermal system of the Late Sarmatian time in the central zone of the Stiavnica stratovolcano. The described cave presents the remarkable' example of hydrothermal limestone cave associated with Miocene volcanism and magmatic intrusions in Central Slovakia.
 


HYPOGENE PALEOKARST IN THE TRIASSIC OF THE DOLOMITES (NORTHERN ITALY), 2014, Riva, A.

In the Triassic of successions of the Italian Dolomites (Northern Italy), there are several examples of different types of hypogene paleokarst, sometimes associated with sulfur or hematite ore deposits.The paleokarst features are related to a regional volcanic event occurred during the Ladinian (Middle Triassic) that affected several carbonate platforms of Anisian-Ladinian age.This study is focusing mainly on the Latemar paleokarst, in the Western Dolomites, and on the Salafossa area in the Easternmost Dolomites.
The karst at Latemar developed as the result of a magmatic intrusion located just below the isolated carbonate platform, developing a system of phreatic conduits and some underground chambers, not justified by the entity of the submarine exposure occurring at the top of the carbonate platform. Most of these features are located about 500 m below the subaerial unconformity and are filled with middle Triassic lavas. Only in one case, the filling is represented by banded crusts now totally dolomitized, with abundant hematite. In this case, the only way to explain the presence of the karst at this depth is to invoke a deep CO2 source allowing the dissolution of the carbonate at such depths: the fact that some phreatic conduits and a possible underground chamber are filled only with lavas is pointing toward an important role of volcanism in karst development.
Salafossa is a well-known mine located in the easternmost Dolomites and has been exploited until 1986, when all the activity ceased. The main metals, in this case, are Zn-Pb-Ba-Fe, exploited within a quite complex paleokarst system developed in several levels, filled by a complex mineralized sequence. The strong dissolution led to the development of voids aligned with the main fault controlling the mineralization, with a proper karst system with phreatic morphologies.
