Melt compositions and fluid regime of crystallization of rare-metal granite and pegmatites from the Sn-W Tigrinoe deposit (Primor’e)

Most of researchers accept that the SnW greisen deposits are genetically related to deeply differentiated granites. However, the nature of the mineral forming fluid and its relation to magmatic processes are still debatable. This study was aimed at determination of the compositions of primary melts...

Description
Summary:Most of researchers accept that the SnW greisen deposits are genetically related to deeply differentiated granites. However, the nature of the mineral forming fluid and its relation to magmatic processes are still debatable. This study was aimed at determination of the compositions of primary melts and the fluid regime during crystallization of granite and pegmatite of the SnW Tigrinoe deposit based on the results of the study of fluid and melt inclusion assemblages in quartz.
