胶西北西岭金矿床地质特征及找矿方向

西岭金矿床位于著名三山岛金矿床的东侧,属于三山岛金矿床向深部延伸的的矿体。西岭金矿床的矿体赋存于破碎蚀变带中,赋矿标高主要为-1 000~-2 000 m,主矿体为Ⅰ号矿体;矿床蚀变带分带明显,沿主断裂的上下盘展布,其形态总体较稳定,属于典型的破碎蚀变岩型金矿床。通过分析矿床成矿规律、控矿构造,结合矿区的地质勘查成果,对矿区成矿远景进行了预测,认为矿区外围北东区域的构造延伸部位是下一步找矿工作的重点。

Geological characteristics and prospecting direction of Xiling Gold Deposit in northwest Jiaodong

Xiling Gold Deposit is located in the east of Sanshandao Gold Deposit. Its orebody is the deep extension of Sanshandao Gold Deposit. The orebody of this deposit is hosted in cataclastic alteration zone,and the level of deposit occurrence is between -1000 m and -2000 m. The main orebody is Orebody I. The distinct alterative zones are dis-tributed along the upper and lower walls of the main fault,and the morphology of orebody is generally stable,indicating that the deposit is a typical fracture zone altered rock gold deposit. Based on the analysis of metallogenic rules and ore-controlling structures,and combined with field exploration work in Xiling Gold Deposit, the metallogenic prospect of the mining area is forecasted. This paper considers that the extension of the northeast direction in the northeastern part of the mining area is the focus of ore prospecting.
