Mineralogy and formation conditions of hydrothermal veins from James Ross Island (Antarctica)
This pilot study focuses on mineralogical and genetic characterization of hydrothermal\nmineralization (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-pha...
