| 摘 要： | 兰家金矿床位于大黑山条垒的金银多金属成矿带中。具有矽卡岩型、破碎带蚀变岩型及细脉浸染型三种类型的金矿体，矿床的形成与晚三叠世泉眼沟序列南泉眼单元的石英闪长岩的多次活动有密切的关系。Ａｕ、Ａｇ、Ｂｉ是成矿元素的特征组合，其原生地球化学特征可做为矿床评价及指导找矿的依据。

| Abstract: | The Lanjia gold deposit is located in the Daheishan banded horst of the Au-Ag polymetal ore-forming belt,in which has three types,i e skarn type,altered rock type in fracture zone and veinlet-disseminated type The formation of the ore deposit is closely related with the multiple actions of quartz diorite of the late Triassic Quanyangou succession(the south Quanyan unit) Au,Ag and Bi show the characteristics of metallogenic elements,and the primary geochemical characteristics can be an indicator for the evaluation of deposit and prospecting of ore deposits |
