摘要
本区位于华北地台北缘东段的和龙地块内,图们江大断裂西侧。自太古代以来,该区经历了多期次的变质作用和复杂的构造岩浆活动,为成矿元素的运移与富集创造了十分有利的地质条件。经过对前人工作资料的收集和研究,总结出了该区的成矿地质和找矿标志。
This area is located in the Helong massif in the eastern part of the northern margin of the North China platform,on the west side of the Tumen River fault.Since Archean,the area has experienced multiple metamorphism and complex tectono magmatic activities,which created favorable geological conditions for the migration and enrichment of ore-forming elements.Through the collection and study of the previous work data,the metallogenic geology and prospecting indicators of this area are summarized.
