| 中文摘要: |
| 本文论述了城门山块状硫化物型铜硫矿、矽卡岩型铜矿、斑岩型铜矿、斑岩型钼矿、铁帽型铁矿和铁帽型金矿的矿床地质持征、控矿因素、主要成矿物理化学条件及成矿作用。该矿床有海底喷气或热泉和岩浆热液两种成因,海西、燕山和表生三个成矿期。块状硫化物型铜硫矿属海底喷气或热泉沉积形成,而城门山多金属铜矿是复成因矿床。 |
| 英文摘要: |
| Chengmenshan Polymetal Deposit can be divided into massive sulfide Cu-deposit, skarn Cu-de-posit, porphyry Cu-deposit, porphyry Ni-deposit, gossan Fe-deposit and gossan Au-deposit. They are formed by submarine exhalative fluid and magrnatie fluid in three metallogenic epoch of Hersynlan, Yanshanlan magmatism and supergene action. Massive Cu, S ore deposits and mineralization in the foot wall are hosted by sedimentary rocks belonging to submarine exhalation or hot spring type of ore deposits on which Yanshanian magmatic fluid were superposed. Gossan gold deposit in top part is resulted from supergene action. Skarn Cu-deposit, porphyry Cu-deposit and porphyry Ni-deposit are formed by magmatie fluid, Late magma fluid of the early Yanshanian diorite intrusion produced skarn Cu-deposit and porphyry Cu-mineralization. Porphyry Cu-deposit and porphyry Ni-deposit are related to quartz porphyrite, mainly formed in Late Yanshanian period. Supergene action bring about the gossan Au deposit. |
