中条山同善天窗铜矿类型及找矿新认识

在总结同善构造—剥蚀窗内成矿地质条件的前提下 ,运用成矿系列理论 ,把区内具有多种表现形式的变基性火山岩型、变砂岩型、大理岩型三大类铜矿分成了八种亚类 ,认为诸类铜矿与区内广泛发育的新太古代基性岩存在着成生联系 ,铜矿的形成经历了一个复杂的过程。早期的海底火山喷发带来的铁、铜、硫等成矿物质 ,经过最初的海水富集、火山活动末期的热液作用富集以及后来区域变质叠加富集进而形成了这一系列矿床。同时提出了新的找矿思路、找矿方法及找矿靶区。

Copper Deposit types of Tongshan Tectonic Window and New Ideas About ore-hunting

Tongshan tectonic window is another good place to form Cu ore in Zhongtiao Mountain area. Various types of copper deposit were found in recent years again. According to the different geocontrols and mineralization characters, we can divide the copper deposits mostly into three types: basic volcanic type, metamorphic sand type and marble type. And they can be divided into eight subtypes. It is suggested that the formation of these kinds of Cu ore is closely related with the extensive New Archeozoic basic rocks. The process of the ore formation may be very compolicated. The Cu, Fe and S elements were from the colcanic eruption in the early stage. And after the enrichment of the sea water, colcanic hydrothermal solution and reginal metamorphic hydrothermal solution, the valuble ore formed.
