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。
羊角尖鋅銅礦床位于大廠礦田龍箱蓋巖體的南西側，北與拉麽鋅銅相鄰。礦(化)體呈透鏡狀、似層狀產齣于花崗巖外接觸帶囉富組地層中，矽卡巖髮育範圍廣。研究認為，本礦床為矽卡巖型鋅銅礦床，成礦過程受到籠箱蓋花崗巖體控製外，還與層間構造和中泥盆統囉富組地層關繫密切。

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.
