摘要
辽北-吉南地区是中国主要太古宙地体出露区之一,地体可以分为花岗岩-绿岩区和高级变质岩区两部分。区域内,尤其是绿岩带内分布着丰富的Au、Cu、Zn、Fe等矿产资源。文章阐述了花岗岩-绿岩区和高级变质岩区的主要地质特征,并通过剖析与绿岩带有关的红透山块状硫化物矿床、夹皮沟脉状金矿床和板石沟BIF铁矿床三个典型矿床,对该地区太古宙矿产形成特点进行了五点总结--矿体就位的层控性、构造环境的一致性、矿床(点)产出的集中性、成矿作用的边缘性和后期矿床的继承性。
The region of northern Liaoning Province and southern Jilin Province is one of the typical area in which the Archean granite-greenstone belts and high-grade metamorphic rock terrains developed well, and produce many mineral resources such as Au, Cu, Zn, Fe. This paper describes the major geological features of granite-greenstone belts and high-grade metamorphic rock terrains, through analysis of three typical deposits related to greenstone： Hongtoushan massive sulfide deposit, Jiapigou lode gold deposit and Broadshigou BIF iron ore deposit, and make a five-point summary： strata-bound ore body, tectonic consistency, deposit concentration, margin mineralization and late deposit inheritance.
