河南省前南华纪变质岩建造组合与矿产特征

摘要

Henan province is located in the southern margin of North China Block and in the Eastern Section of Qin Qikun orogenic belt, with complex structure, crossing two grade Ⅰ tectonic units, and is an important area to study tectonics, metamorphic rocks formation assemblages and ore bearing formation. Metamorphic rocks’ structures in different tectonic environments often have certain metallogenic relation with specific mineral resources. This paper analyzes and summarizes the age of Pro-Nanhua period metamorphic strata and the mineral characteristics of metamorphic rock formation assemblages. The research on metamorphic rock formation assemblages has vital significance to study the formation of metamorphic deposits, sedimentary metamorphic deposit and metamorphic volcano deposit.%河南省位于华北陆块南缘和秦祁昆造山带东段，跨两个一级构造单元，构造复杂，是研究构造、变质岩石建造组合、含矿建造及对成矿作用的重要地带，不同大地构造环境下形成的变质岩石构造组合往往对特定的矿产资源有一定的成矿专属性。本文对河南省前南华纪变质地层形成时代、变质岩石建造组合和成矿特征进行了分析总结。加强变质岩石建造组合的研究，对探讨变质矿床、沉积变质矿床、变质火山成因矿床的形成具有重要的意义。
