新疆阿舍勒火山岩型块状硫化物铜矿硫、铅同位素地球化学研究

Sulfur and lead isotopic geochemistry of the volcanic rocks massive sulfide copper deposit in Xinjiang

通过对新疆阿舍勒铜矿区Ⅰ号矿床与Ⅱ号矿床进行分析可知,二者有着很大的差异,Ⅰ号矿床硫来自火山喷气,金属与细碧岩同源,Ⅱ号矿床硫是多元的,金属来英角斑质凝灰岩的海水淋滤,铅同位素资料当中反映了酸性火山两个源区。

According to the analysis of Ⅰ deposit and Ⅱ deposit in Ashele Copper Mine, Xinjiang, there is a great difference between them. The sulfur in Ⅰ deposit comes from volcanic exhalation, the metal is homologous to spilite, the sulfur in Ⅱ deposit is multicomponent, and the seawater leaching of metal-Leying horny tuff reflects the acid in the lead isotope data. Two sources of sexual volcanoes.
