Textural characteristics and trace element distribution in carbonate-hosted Zn-Pb-Ag ores at the Paleoproterozoic Black Angel deposit, central West Greenland

The Black Angel deposit represents the most important base metal deposit in Greenland, having produced 11.2 million tons of Pb-Zn-Ag ore from 1973 to 1990. The deposit is hosted by a greenschist facies calcitic marble of the Mârmorilik Formation of the Paleoproterozoic Karrat Group. The ore consists of sphalerite, pyrite, and galena, with minor amounts of chalcopyrite, arsenopyrite, tetrahedrite, freibergite, tennantite, stannite, briartite,...
