河北省承德市寿王坟铜矿床成矿规律及找矿方向研究

Study on Metallogenic Regularity and Prospecting Direction of Shouwangfen Copper Deposit in Chengde City,Hebei Province

寿王坟铜矿床坐落于河北省鹰手营子区寿王坟镇,构造位置位于中朝准地台、燕山台褶带的南缘、马兰峪复式背斜的北翼,北东向寿王坟—小寺沟杂岩体铜钼成矿带上,区域成矿地质条件优越。通过梳理区域地层、构造、岩浆岩、矿体特征、矿石矿物成分、矿石结构以及围岩蚀变,得出该矿床是地层+构造+岩浆共同活动的产物,接触构造带、成矿母岩和铜铁矿相互依存;矽卡岩化是直接找矿标识,同时南翼接触带仍是主要找矿空间。

The Shouwangfen copper deposit is located in Shouwangfen Town,Yingshouyingzi District,Hebei Province.The tectonic position is located in the southern margin of the fold belt of the Sino-Korean platform and the Yanshan platform,and the northern wing of the Malanyu complex anticline.The copper-molybdenum metallogenic belt of the Shouwangfen-Xiaosigou complex in the northeast direction has excellent regional metallogenic geological conditions.By combing the regional strata,structures,magmatic rocks,ore body characteristics,ore mineral composition,ore structure and wall rock alteration,it is concluded that the deposit is the product of strata+structures+magma activities.Contact tectonic zone,metallogenic mother rock and copper-iron ore are interdependent.Skarnization is a direct prospecting indicator,and the southern contact zone is still the main prospecting space.
