摘要
本文对新疆阿舍勒块状铜锌碱化物矿体的内部构造及矿物共生组合进行了研究,与现代海底硫化物矿床的矿物分带作了比较,初步认为影响该矿床矿物分带的主要因素是成矿溶液的初始温度。
The internal structure and mineral paragenesis in No. I orebody of Ashelei massive copper-zinc sulfide deposit have been studied, there are zoning phenomena of ore minerals, ore fabrics, major and trace elements of the ore and S isotopic constituents in this orebody, all of them were contrasted with mineral zoning in modern submarine sulfide and Kuroko ore deposits in order to improve our understanding on the origin of sulfide zoning in this deposit.
It is suggested that original temperature of the ore-forming solutions is a key factor of forming mineral zonal sequence in this deposit. If the original tempera lure is
higher than 300℃ ,the orebody would be mineral zoned, if it is lower than 250-
200℃ , the orebody would show no mineral zoning. Besides, volcanism and physicochemical factors of the ore-forming solutions are also factors of forming mineral zones.
