中文摘要:

文章讨论了扬子地台北缘地壳演化、地层分区、构造分带和金成矿特征。确定大部分大中型金矿位于扬子地台北缘裂谷系,微古陆内外接触带。认为该区经历了复杂的地质构造演化,形成了不同的金矿类型与矿化组合。最后总结了找矿方向。

英文摘要:

This paper outlines crustal euolution, stratigraphic division and tectonic zoning in the north margin area of Yangtz platform. The area is characterized by complex evolution of geology and tectonism during which the characteristic gold deposit types and mineralization associations were formed. Then are pointed the ore-searching directions for the area.
