摘要
内蒙古温家地西金矿区紧邻柴胡栏子金矿区,位于其南侧。结合该地区勘查工作成果,讨论了区域成矿地质背景、矿区地质特征、矿床地质特征、矿床成因类型及成矿阶段,并结合历年来坑道及钻探工程揭露的矿体情况,确定了下一步找矿方向。研究表明:(1)矿区内发现了10条工业金矿体,其中Ⅰ-9~#、Ⅰ-9-3~#、Ⅰ-9-2~#矿体为主矿体,呈平行分布,均为隐伏矿体,厚度较稳定,Au品位分布较均匀;(2)矿床形成于中浅成、中等温度、酸性环境,属于中—低温热液充填型及蚀变岩型矿床;(3)矿体南东延伸及深部缺少工程控制,存在较大的找矿空间。
The gold mining area in the west of Wenjiadi Area is close to the Chaihulanzi gold depos- it, it is located in the south of Chaihulanzi gold deposit. Based on the achievements of geological investi- gation of the mining area, the regional metallogenic geological background, geological characteristics of the mining area and deposit, deposit genesis and metallogenic stage area discussed, besides that, according to the ore-bodies informtion obtained by pit and drilling engineering in previous years, the further prospec- ting direction of the mining area is studied. The study results show that：①10 industrial gold ore-bodies are found in the mining area, among them, the ore-bodies named I-9#, I-9-3# and I-9-2# are the main ore-bodies in the mining area, they belongs to concealed ore-bodies, they are distributed in parallel, and the thickness of them and grade are relatively stable and uniform; ②the deposit is formed in medium-hypa- byssal, medium-temperature and acidic environment, it belongs to medium-low hydrothermal filling type and ahered-rock type deposit;③the southeast and deep of ore-bodies can not be controlled by some relat- ed engineering,which indicated that the prospecting potential of the areas are good.
