Ore mineralogy and mineral chemistry of quartz-polymetallic veins in Caleta Argentina, Livingston Island, Antarctica

Abstract

The quartz-polymetallic veins from Caleta Argentina, Livingston Island, Antarctica consist of pyrite, chalcopyrite, galena, and sphalerite. Chalcopyrite is the most common ore mineral and with concentrations of Ag (average 240.51 ppm). Sphalerite contains Ag (average 50.82) and Au (average 0.31 ppm), and pyrite – Au from not detectable to 1.03 ppm (average 0.59 ppm) and Ag from not detectable to 54.33 ppm (average 32.52 ppm). Caleta Argentina, as one of the ore occurrences in Hurd Peninsula, has to be correlated with the other research area such as the Bulgarian Antarctic Base, the Bulgarian Beach, and Sally Rocks.
