辽宁黄土岭地区金矿地质特征及找矿方向

Geological characteristics and prospecting direction of gold deposit in Huangtuling area,Liaoning Province

通过辽宁省本级地质普查工作,在黄土岭地区白家堡子村发现了较好的金多金属矿化线索,矿床地质特征研究标明矿床成因为岩浆期后热液型金矿,矿体切层产出,矿体围岩主要为辽河群里尔峪组(浅)变粒岩及花岗伟晶岩。该矿床的发现突破了区域上金矿主要受辽河群盖县组、大石桥组地层控制的限制,首次在里尔峪组地层发现金矿体,为区域上金矿找矿预测扩大了空间。

This study is based on the geological survey project of Liaoning Province,a good clue of gold polymetallic mineralization was found in Baijiapuzi village of Huangtuling area,The geological characteristics of the deposit indicate that the deposit is formed by post-magmatic hydrothermal gold deposit and the ore body is produced by stratification,the orebody’s surrounding rock are mainly pelletized rocks and granitic pegmatite of Lieryu formation of Liaohe Group.This discovery broke through the limitations of the gold deposits controlled by the Gaixian formation and the Dashiqiao formation in the Liaohe Group in this area,gold ore bodies were found in Lieryu formation for the first time,It expands the space for the prospecting prediction of gold deposits in the region.
