摘要
辽宁省葫芦岛市东青堡银锌矿床产于山神庙—钢屯—高桥EW向成矿带东段,是一处以银为主、伴生锌、铅、金的多金属矿床。全区共有3条工业矿体,产于雾迷山组燧石条带白云岩中,受近EW向基底断裂及其上盘的爆破角砾岩筒和花岗斑岩控制,成矿物质主要来源于地幔或下地壳,成矿热液来源于岩浆水。矿床成因类型为与酸性次火山岩和爆破角砾岩有关的中低温热液矿床。
Dongqingpu silver-zinc deposit occurs in the east section of Shanshenmiao-Gangtun-Gaoqiao metallo-genic belt in Huludao City,Liaoning Province.It is a polymetallic deposit mainly with silver,associated zinc,lead and gold.There are three industry orebodies in this area,produced in bands dolomite in Wumishan Group,con-trolled by EW-trending basement fault（F1）and esplosive breccia pipe,granite porphyry in its hanging wall.The metallogenic material is mainly from mantle or lower crust,and the metallogenic hydrothermal is from magmatic water.So,we can see that the ore-forming type is a medium-low temperature hydrothermal deposit which is related to acidity sub-volcanic rock and esplosive breccia.
