郴州—桂阳地区内生金属矿床成矿系列与矿床模式

Metallogenic Series and Deposit Models of Endogeneous Polymetallic Deposits in Chenzhou—Guiyang District

郴州一桂阳地区,按其成矿元素组合和矿床在空间上分布规律等,内生金属矿床以斜贯全区的(?)县一郴州一蓝山深断裂为界,南部为与酸性中浅成花岗岩类有关的钨锡多金属矿床成矿系列,北部为与中酸性深源浅成花岗闪长岩类有关的铅锌多金属矿床成矿系列。建立东坡、黄沙坪、宝山等矿田矿床组合模式。

In terms of the association of ore-forming elements and the spatial distribution, the endogeneous polymetallic deposits in Chenzhou-Guiyang district can be divided into two series by a boundary line, that is, a deep fault which cuts through the whole area, striking along NE-SW direc-tion. To the north, the metallogenic series consists of Ph-Zn polymetallic deposits related to hy-pabyssal, intermediate-acid granodiorites derived from deep seat, and to the south, it is the series which is composed of W-Sn polymetallic deposits related to esogene-hypabyssal, acid granotoids. In this paper the deposit assemblage models of Dongpo, Huangshaping and Baoshan ore fields are also established.
