| 摘 要： | 紫金山矿田内,自地表往深部,发育早白垩世中酸性火山岩、次火山英安斑岩、浅成相花岗闪长斑岩、中深成相花岗闪长岩,构成中酸性火山-侵入岩系列。围绕着紫金山火山机构发育强烈的蚀变矿化,形成高硫型浅成低温热液铜金矿、低硫型浅成低温热液银金矿和斑岩型铜（钼）矿床。矿田内各类铜金银矿床存在着密切的时空及物源联系,它们在时间、空间上连续演化,都是同源含矿中酸性岩浆在同一成矿背景之下于不同演化阶段的产物。含矿热液的物化性质及时空迁移决定了它们在不同地质部位产出不同的矿床类型,构成与中酸性次火山-斑岩有关的浅成低温-斑岩铜金银矿成矿系统。

| Abstract: | The rocks in the Zijingshang ore field are from the surface to depth as follows: Lower Cretaceous intermediate-acid volcanic rocks, subvolcanic dacite-porphyry, hypabyssal granodiorite-porphyry and middle- and deep-level porphyritic granodiorite, forming an intermediate-acid volcanic-intrusive sequence. Strong alteration-mineralization occur around the Zijinshan volcanic edifice, forming high-sulfur epithermal Cu-Au deposits, low-sulfur epithermal Ag-Au deposits and porphyry Cu (Mo) deposits. In the ore field, various types of Cu-Au-Ag deposit have close temporal-spatial and material source relations. They evolved continuously in terms of time and space and are products of consanguineous ore-bearing intermediate-acid magmas in the same background of mineralization but in different stages of evolution. The occurrence of different types of ore deposit in diverse geological positions depended on the physico-chemical properties and temporal-spatial migration of ore fluids, thus forming an epithermal porphyry Cu-Au-Ag mineralization system related to intermediate-acid subvolcanic rocks and porphyry. |
