河南韩老庄铁矿地质条件及找矿模式

Metallogenic geological conditions and prospecting model of Hanlaozhuang iron mine in Tongbai County,Henan

河南桐柏县韩老庄铁矿是位于北秦岭褶皱带毛集铁、铜成矿带内的小型矿床。文章在研究以往地质资料的基础上,结合该区的地质勘查工作,通过分析铁矿体区域位置、赋矿地层、磁异常情况、矿体特征,以及矿石结构、构造、矿石矿物、脉石矿物、围岩蚀变等信息,划分成矿阶段,总结找矿标志及找矿模式,为区内及外围的中深部找矿工作提供依据。

TongbaiHanlaozhuang iron mine is located in the North Qinling Fold Belt and Maoji Iron and Copper Metallogenic Belt.Based on previous geological data,this paper classifies the metallogenic stages by analyzing the regional location of iron ore bodies,ore-hosting strata,magnetic anomalies,ore body characteristics,and information of ore structure,ore minerals,gangue minerals,wall rock alteration,and summarizes prospecting criteria and prospecting model.The model can provide a basis for prospecting in the middle and deep part of the area and its periphery.
