某含钽铌花岗岩成岩成矿温度的研究

摘要

Formation temperatures are obtained for a tantalum-niobium-bearing granite(512-530℃）,the feldspar-quartz zone(495℃）,the quartz zone(483℃）in the pegmatoid and wolframite-quartz vein(262-273℃,no pressure corection has been made through studies of fluid inclusions in quartz,wolframite,Mn-rich columbite microlite and other minerals,The results demonstrate that petrogenesis and metallogenesis of this district are a protracted,multistage process.
