河北沟苔青铁矿地质特征与成矿规律

Geological characteristics and metallogenic rulesof Goutaiqing iron mine,Hebei

涞源县是河北省铁矿资源地之一,境内铁矿床主要为沉积变质型和夕卡岩型,后者主要围绕王安镇岩体产出,而位于岩体西南侧的沟苔青铁矿具有夕卡岩型矿床的典型特征,早期夕卡岩—晚期夕卡岩—氧化物—早期硫化物—晚期硫化物阶段均有显示;此外它还有其特殊之处,如主—被动侵位机制、超覆接触关系、伴生多金属矿产等;因此虽然它规模较小,但总结和分析其成矿特征及规律,对附近区域寻找同类矿产具有一定的指导意义。

Laiyuan county is the iron resource field of Hebei province. The mean iron deposit there is sedimentary metamorphic type and skarn type. The latter mainly deposits around the Wanganzhen rock body. While Goutaiqing iron deposit which is located in south - west of the rock body has typical feature of skarn deposit. All the phases of early skarn - late skarn - early sulphide - late sulphide are showing there. Besides, Goutaiqing iron deposit has its special features, such as ： active - passive invasion mechanism, over-lapping contact relationship, accompanied polymetallic mineral, and so on. So though its size is relatively small, it has a certain directive value to seek same mineral in the vicinity by summarizing and analyzing its metallogenic characteristics and rules.
