吉林东部中生代金属矿床成矿作用分析

Mineralization of Mesozoic Metal Deposits in Eastern Jilin Province

本文通过查阅资料的方法汇总了吉林东部中生代有色金属矿产资料信息,通过综合研究总结了吉林东部中生代金属矿床成矿作用。本文研究成果认为该区域中生代成矿作用可分为印支晚期Cu-Ni成矿作用、燕山晚期Cu-WAu-Ag多金属金矿作用和燕山早期Cu-Pb-Zn-Au-Ag-Sb-W-Mo等多金属成矿作用,其成矿时间集中于燕山早期(180Ma^160Ma)和燕山晚期(130Ma^110Ma),本文的研究成果为进一步进行区域找矿勘查提供借鉴意义。

This paper summarizes the Mesozoic nonferrous metal mineral information in the east of Jilin Province by means of consulting data, and sums up the mineralization of Mesozoic metallic deposits in eastern Jilin Province. The results of this paper suggest that the Mesozoic mineralization in this area can be divided into the late Indosinian cu-ni mineralization, the role of late Yanshanian Cu-W-Au-Ag polymetallic deposits and the early Yanshanian Cu-Pb-Zn-Au-Ag-Sb-W-Mo and other polymetallic mineralization, and the mineralization time was concentrated in the early Yanshanian（180 Ma^160 Ma） and Late Yanshanian（130 ma ~ 110 ma）, the research results of this paper provide reference for further exploration of regional prospecting. Key words： Eastern Jilin; mesozoic; Metal Minerals.
