Ore-forming mechanism of quartz-vein-type W-Sn deposits of the Xitian district in SE China: Implications from the trace element analysis of wolframite and investigation of fluid inclusions
Quartz-vein orebodies in Xitian district are the dominant mode of mineralization and can be divided into three stages. Trace element and REE occurrence state in wolframite of two stages in Xitian district are discussed in detail. Physical-chemical conditions and mechanism of the ore-forming fluid in Xitian district are revealed.
