摘要
矿区位于鲁东地区沂沭断裂带之东侧,区域构造—岩浆活动频繁,成矿地质条件良好,找矿潜力巨大。本文研究表明:矿区位于北东向和北西向断裂破碎带的交汇部位,水文地质条件较简单;矿山地下水类型主要为第四系孔隙水、碎屑岩类裂隙水和基岩裂隙水,浅部水质为HCO3-Ca·Mg型,深部为SO4·Cl-Na型水,矿区水质较好。地下水主要依靠大气降水的补给,以地表径流排泄;深部地下水受北西向断裂活动影响,裂隙较发育,富水性强。
The mining area is located in the east of the Yishu fault zone in the eastern Shandong area,the regional tectonic-magmatic activities are frequent,the metallogenic geological conditions are good,and the prospecting potential is huge.This study shows that the mine is located at the intersection of NE and NW trending fault and fracture zones,and the hydrogeological conditions are relatively simple.The groundwater types of mine are mainly Quaternary pore water,clastic rock fissure water and bedrock fissure water.The shallow water quality is HCO3-Ca·Mg type,and the deep water is SO4·Cl-Na type.The mine water quality is better.Groundwater mainly depends on the supply of meteoric precipitation and is discharged by surface runoff.The deep groundwater is affected by the NW trending fault activities,the fissures are developed and the water content is strong.
