Tracking fluid sources for skarn formation using scapolite geochemistry: an example from the Jinshandian iron skarn deposit, Eastern China

Scapolite occurs as the major halogen-bearing phase at all paragenetic stages of skarn formation and mineralization in the Jinshandian iron skarn deposit, Eastern China. Here we integrate geochemical characteristics of scapolite with in situ B and Sr isotopes of associated tourmaline and fluorapatite, respectively, to trace the sources and evolution of the fluids responsible for mineralization in this deposit. Pre-ore stage I scapolite has molar...
