摘要
本文对浙东地区典型的陆相火山、次火山热液型矿床——大岭口银铅锌矿床中闪锌矿、方铅矿、黄铜矿、黄铁矿及毒砂,着重进行了成分标型的研究,指出:闪锌矿的Zn/Cd比值(492～148),方铅矿的Bi/Sb比值(17.7～0.10)皆是各自形成温度的重要标志;闪锌矿;黄铁矿及黄铜矿富As,黄铁矿、毒砂富Sb是其重要的标型特征,从这些矿物的微量元素含量及浙东地区的地质特征来看,在本区,尤其是铅锌银矿区,寻找中,低温火山热液型金矿床是很有希望的。
This paper is focussed on the compositional typomorphic peculiarities of sphalerite, galena, chalcopyrite, pyrite and arsenopyrite in the terrestrial volcanic or sub-volcanic hydrothermal ore deposit-Dalingkou Ag-Pb-Zn deposit in eastern Zhejiang Province. The. Zn/Cd ratios (492～148) of sphalerite and Bi/Sb ratios (17.7～0.1) of galena are important indicators of formation temperatures. This study also shows that the sphalerite and chalcopyrite are rich in As and the pyrite and arsenopyrite in Sb. Based upon the concentrations of trace elements in these sulphides and the geological setting, it is considered that eastern Zhejiang, especially its Pb-Zn(Ag) mining district, it is a prospective area of mesoepithermal gold deposits.
