浅析青海片区锡铜多金属矿床成因及成矿规律

Analysis of Genesis and metallogenic regularity of tin copper polymetallic deposit in Qinghai area

青海片区锡铜多金属矿床主要分布于两级挤压的多动断层滞留带内,与早石炭纪到晚侏罗纪的细粒黑云母花岗岩有着密切的关系。上中生代三叠纪火山岩系和玄武系淡色花岗岩系是该片区内最主要的岩石体系,不同时期的火山岩可以组成不同类型矿体矿床。本文对青海片区锡铜多金属矿床进行了叙述和研究,为该片区的地质勘探打下理论基础。

Qinghai area tin and copper polymetallic ore deposits are mainly distributed in two-stage extruding the hyperactivity of fault belt, and the late carboniferous to early Jurassic into fine grained biotite granite have a close relationship. In Mesozoic Triassic volcanic rock series and basaltic series light granite is the most as long as the system of rock, the area in different periods of volcanic rock can control different types of ore deposits. In this paper, the qinghai area tin copper polymetallic deposit has carried on the detailed narration and research, lay a theoretical basis for geological exploration in this area.
