摘要：

山东乳山西涝口金矿床位于郭城断裂以东,赋存于新元古代震旦期玲珑超单元九曲单元二长花岗岩内及其与古元古代荆山群地层的接触带内,矿体主要受北东向、近东西向断裂控制,呈透镜状产出,具黄铁矿化、硅化、碳酸盐化等蚀变,由于控矿构造、围岩岩性特征等不同,矿床类型分为黄铁绢英岩化型和多金属硫化物型。通过分析认为该区主要工业矿体为多金属硫化物型,赋存于玲珑超单元九曲单元二长花岗岩(区内称牧牛山岩体)与荆山群地层的接触带中,指出了今后的找矿方向。

Abstract:

The Xilaokou gold deposit is located in the east to Guocheng fault.The deposit occurs in the intersection between the Linlong monzonite granite bodies of new Proterozoic Sinian period and the Jinshan stratum of ancient Proterozoic.The ore bodies are controled by NE and nearly EW trend faults.They formed with lens shape and with pyritization,silication and carbonation alternation.Because of the difference of ore-controlling structure and their wall rocks characteristic,the deposit bed types are divided into pyrite sericite-quartz type and multi-metal sulfide type.Its prospecting direction is pointed out.
