摘要
浙东南(绍兴-江山断裂带以东)地区,在燕山晚期存在着统一的区域性金银和铅锌成矿作用.它们皆属浅成中-低温热液矿床.隆起带和坳陷带中的矿床具有不同的形成机制.金银矿床规模与脉石英包裹体中气相CH_4/H_2O和CO_2/H_2O比值正相关.
On the cast of the Shaoxing-Jiangshan fault zone in southeastern Zhejiang province, there exists
Au-Ag-Pb-Zn mineralizations of identical regional metallogenesis and of the late-Yanshanian stage. All
of them belong to shallow-seated mesothermal-epithermal deposits. Deposits situated in upwarping and
downwarping zones are of different genetic mechanism. The scale of Au-Ag deposits bears a positive
correlation with gaseous phase ratios (CH_4/H_2O and CO_2/H_2O) of inclusions in vein quartz.
