摘要
崔家沟铁矿地处涞源-武安成矿带涞易矿床集中区。磁铁矿体赋存于燕山期黑云花岗岩侵入白云岩形成的一套蛇纹石(透辉石)矽卡岩中。通过研究矿床地质特征,归纳地层、岩浆岩和构造等控矿因素,认为成矿母岩性质的黑云花岗岩规模大,与白云岩接触交代形成广泛分布的矽卡岩接触带,同时接触带构造和捕掳体构造裂隙发育。因此,在区内矽卡岩型铁矿的找矿前景较大。
The Cuijiagou iron ore is situated on the Laiyuan-Yixian mineral deposit concentration area,Laiyuan-Wuan metallogenic belt.The magnetite orebody is hosted in a set of serpentine(diopside)skarn formed from Yanshanian granitite intruded into dolomite.Through ore deposit geological features study,summed up ore controlling factors including stratum,magmatic rock and structure,have considered that the scale of metallogenic parent rock-magnetite is very large,and through contact metasomatism with dolomite has formed widely distributed skarn contact zone,and well developed structural fissures in contact zone and xenolith.Thus the prospecting prospect of skarn type iron ore deposit is referable in the area.
