摘要
石柱子花岗闪长岩体形成于晚侏罗-早白垩世,岩石属钙碱系列,形成于造山带或岛弧构造环境。岩体的副矿物组合及矿物组合标型研究表明,锆石-磷灰石-锐钛矿(金红石).锆石-锐钛矿(金红石).锆石-磷灰石-榍石-金红石(锐钛矿)等3种副矿物组合类型;黄铁矿-黄铜矿-斑铜矿(黝铜矿)-重晶石,黄铁矿-黄铜矿,黄铜矿-方铅矿-重晶石,黄铁矿-黄铜矿-重晶石,黄铁矿-黄铜矿-辉钼矿,黄铁矿-白钨矿,黄铁矿-重晶石等7种矿石矿物组合类型,可作为本区寻找斑岩铜矿的矿物组合标志。
In the Late Jurassic -Early Cretacous,the granodiorite body in Shizhuzi, Kuandian coun-ty,being of calc-alkaline series,formed in an environment of orogenic belt or island arc,Studies on the characterisics of the mineral assemblages show that 3 kinds of accessory min-eral assemblages:zircon- apatite-anatase (rutille),zircon-anatase(rutile),zircon-apatite-ru-tile(anatase),and 7 kinds of ore mineral assemblages:pyrite-chalcopyrite-bronite(te-trahedrite )-barite,pyrite-chalcopyrite,chalcopyrite-galena-barite,pyrite-chalcopyritemolybdenite,pyrite-scheelite,pyrite-barite can be used as the criteria for copper depositprospecting.
