【摘要】 <正>一、地质背景本区位于扬子准地台中的下扬子台坳的中段,次级构造单元为九江台陷。区内经历了多次构造运动,最早的晋宁运动,使前震旦纪地槽型沉积褶皱、回返,进入准地台发展阶段,加里东运动使之抬升,遭受剥蚀。海西运动,主要表现为振荡运动,晚古生代到早三叠世地壳升降较为明显,海陆交替,早期还经受长期时间的剥蚀(泥盆系缺失)
【Abstract】 Copper deposits in the refered area are composed of two genetic types:one is related to submarine exhalative activity,another is related to intermediate-acid supergene to ultrasupergene intrusive activity.The latter includes skarn and porphyry copper deposits.These types of Cudeposits may occur together and form a composite copper deposits which we termed as"trinity".
