摘要
东川大型—超大型铜、铁、金综合矿区,受改造形成的层状富铜矿;后生的含银脉状铜矿;普遍伴生Nb2O5的后生含铜磁铁矿及成因与深部隐伏碱性岩有关的金矿,其工业矿体的形成都与多旋回火山—岩浆(晋宁—澄江期与燕山—喜马拉雅期为主)的改造、成矿作用有关。
The formation of commercial ore body of bedded Cu - rich deposit formed by reformation, epigenetic Ag - high veined Cu deposit, epigenetic Cu - bearing magnetite deposit general- ly with associated Nb205 and Au deposit related with deep blind alkaline rock in genesis is related with reformation--metallogenesis of muhicycle volcanism--magrnatism （mainly in the Jinning - Chengjiang period and Himalayan period）.
