广西南丹县羊角尖锌铜矿床地质特征及成矿条件

摘要

羊角尖锌铜矿床位于大厂矿田龙箱盖岩体的南西侧，北与拉么锌铜相邻。矿(化)体呈透镜状、似层状产出于花岗岩外接触带罗富组地层中，矽卡岩发育范围广。研究认为，本矿床为矽卡岩型锌铜矿床，成矿过程受到笼箱盖花岗岩体控制外，还与层间构造和中泥盆统罗富组地层关系密切。%Yangjiaojian Zn-Cu deposit is located in the southwest of Longxianggai rock body in Dachang ore field and is adjacent to Lame Zn-Cu deposit.The orebodies (or mineralization)occur in the Luofu Formation of outer contact of granite body in lenticular or stratoid.The skarn is developed and widely distributed.It is suggests that the deposit is a skarn-type Zn-Cu deposit,and the ore-forming process is controlled by Longx-ianggai granite body and is closely related to the interlayer tectonic and the middle Devonian Luofu Forma-tion.
