吉林省非金属矿产区域成矿规律的分析

ANALYSIS OF REGIONAL METALLOGENIC REGULARITIES OF NONMETALLIC MINERAL RESOURCES IN JILIN PROVINCE

吉林省有丰富的非金属矿产资源,它们的形成及空间展布,赋存的层位等多受沉积盆地的控制,同古气候及环境的演化关系密切,或者与岩浆活动和区域变质作用有联系。这些控矿因素、条件均与区域大地构造环境及地质构造发展演化的阶段相吻合,从这点出发概略分析非金属矿产区域成矿规律。吉林省跨越南部中朝准地台、北部吉黑地槽两大构造单元。

This paper describes systematically the formation and evolution of the Jonggang continental nucleus,and the assemblage characteristics of nonmetal- lic mineral deposits in three major tectonic evolutional stages in the Palaeo- Asiatic tectonic domain and the Marginal-Pacific tectonic domain. The authors summarize the relationship between the horizons where a lot of mineral deposits occurred in ten nonmetallic metallogenetic stage and the tectonic setting.
