| 摘 要： | 东秦岭二郎坪群蛇绿岩中广泛发育火山成因块状硫化物矿床。火山演化从早期到中晚期分别形成铁矿层、火山成因块状硫化物矿床和黄铁矿化层。矿床具有层控性及距火山喷发中心带距离不同而控制的分带性规律，还有厚层基性熔岩形成铁矿、酸性火山岩赋存铜—锌型或铅—锌—铜型矿的岩性成矿专属性。矿床中伴有不同规模的金银矿化。

| Abstract: | Volcanogenic massive sulfide deposits occur widely in the ophiolite of the Erlangping Group of the Eastern Qinling Mountains. Early to late stage volcanic evolution resulted in the formation of iron formations, sulfide deposits and pyrite mineralization beds. The sulfide deposits have the stratabound nature and show zoning controlled by different distances from the eruption center. Moreover, there are metallogenetic specializations of thick bedded basic lava hosted iron deposits and acid volcanic rock hosted copper zinc deposits or lead zinc copper deposits. The deposits also contain gold silver mineralization. |
