东风山金矿床地质特征及成因探讨
|
摘要
为扩大东风山金矿找矿远景,在开展金矿床成矿地质背景、地质条件、矿体特征、矿石类型、矿物组分等方面研究基础上,通过总结成矿因素与控矿条件,认为沉积分异作用形成的硅铁建造为金成矿的矿源层,区域变质作用使含矿地层内金元素进行迁移与初步富集,花岗岩侵入带来的热源驱使含矿物质重新活化、迁移、再富集形成金矿体。初步认定东风山金矿床成因类型为沉积-变质型金矿床,为寻找类似金矿床具重要指导意义。
The researches on metallogenic geological background,geological conditions,orebodies characteristics,ore types,mineral components of the gold deposits were carried out,the purpose of which were to expand the peripheral metallogenic prediction and select target areas in Dongfengshan gold deposits. By summing up the metallogenic factors and ore controlling conditions,the gold ore source layer was considered as the ferrosilicon formations of sedimentary differentiation; The gold was migrated and enriched in containing ore under the action of regional metamorphism; The mineral was turned into the gold deposits,which was reactivated,remigrated and enriched by the heat from granite intrusion; Initially Dongfengshan gold deposit is identified as genetic type of sedimentary metamorphic type gold deposit,which provides an important guiding significance for similar gold deposit.
