Original Abstract

This pilot study focuses on mineralogical and genetic characterization of hydrothermal mineralization (epigenetic calcite veins) in the Cretaceous rocks of the James Ross Island. The studied veins occur most frequently as filling of fissure systems which are perpendicular to bedding planes. Two-phase aqueous primary, pseudosecondary, and secondary fluid inclusions were identified in the collected samples. The majority of homogenization temperatures for primary or pseudosecondary inclusions range from 200 to 320 °C. Fluid inclusions are characterized by low salinity between 1.0 and 6.5 wt. % NaCl equiv. In the sample JRK 07, the presence of heulandite-group zeolite was recognized, which is indicative of a genetic relation with volcanic activity.
