福建省德化县双旗山金矿含矿构造地质特征浅析

Ore-bearing structure analysis of shuangqishan gold deposit,dehua county,fujian province

双旗山金矿体主要贮存于中-晚元古代大岭组变质岩地层中,受剪切带构造控制,与燕山期酸性岩浆侵入活动密切相关,是典型的受剪切带控制的热液叠加蚀变型矿床。矿区含矿剪切带构造分为陡倾韧-脆性剪切带和缓倾脆-韧性剪切带2种类型,缓倾脆-韧性剪切带是最重要的控矿构造和容矿构造,也是实现找矿突破的关键。

The shuangqishan gold ore body is a typical hydrothermal superposition alteration deposit controlled by the shear zone,which is mainly stored in the metamorphic strata of the middle-late proterozoic daling formation and is controlled by the shear zone structure.The structure of ore-bearing shear zone in the mining area is divided into two types:steep dip ductile ductile shear zone and slow dip brittle ductile shear zone.
