摘要
松树卯后东沟铅锌矿位于八家子—杨家杖子岩浆热液有色金属成矿带的东北端.区内断裂构造发育,燕山期早期花岗闪长岩侵入,为铅锌矿成矿提供了充分的热动力条件和物质来源,于地层接触部位形成破碎蚀变带、矽卡岩化,从而形成热液充填交代型矿床.破碎蚀变带、矽卡岩化是本区最直接的找矿标志.通过研究矿床地质特征和成矿条件,对找矿方向提出建议.
Abstract
The Songshumao Donggou lead-zinc deposit is located at the northeast end of the Bajiazi Yangjiazhangzi magmatic hydrothermal non-ferrous metal mineralization belt.The development of fault structures in the area and the intrusion of early Yanshanian granodiorite provided sufficient thermodynamic conditions and material sources for the mineralization of lead-zinc deposits.The formation of fractured alteration zones and skarnization at the stratigraphic contact sites resulted in the formation of hydrothermal filling and metasomatism type deposits.The fractured alteration zone and silicification are the most direct prospecting indicators in this area.By studying the geological characteristics and mineralization conditions of mineral deposits,suggestions for prospecting directions are proposed.
