西秦岭中川地区构造-岩浆活动及微细浸染型金矿成矿作用分析
STRUCTURAL AND MAGMATIC ACTIVITY AND THE RELATION TO GOLD MINERALIZATION IN ZHONGCHUAN AREA, WEST QINLING
摘要
Abstract
Zhongchuan area underwent ductile→ductile-brittle→brittle deformation with 3 periods and 5 times of magmatic intrusion. Liba style Au deposits are medium-low epithermal-magma reworked deposits. Late palaeozoic sedimentary formations are the source beds. Ore formation included the early Au mobilization and transportation, tectonic-hydrothermal rework and Indo-China-Yanshanian magmatism rework. The regional deep fractures are main conduit of ore fluid which is dominated by meteoric water.关键词
