Skarn formation and tin enrichment during regional metamorphism: The Hämmerlein polymetallic skarn deposit

open access: yesLithos, 2019
Abstract The Hammerlein Sn-rich polymetallic skarn deposit (Erzgebirge, Germany), which is hosted by Variscan schists and gneisses, includes garnet, amphibole, pyroxene, and magnetite skarns that formed during regional metamorphism at ~340 Ma. The skarn deposit was overprinted during the intrusion of the ca. 320 Ma Eibenstock granite.
