河南老湾矿区金矿矿体特征与资源远景评价研究

Research on the characteristics of gold ore bodies and the evaluation of resources in the old bay area of Henan

老湾矿区大地构造位置属秦岭褶皱系、桐柏-大别褶皱带,秦岭区、桐柏-大别分区。桐柏山北坡是我国著名的矿化集中分布区之一,它们具有集群成带分布特点。本文对矿区地层特征、构造特征进行详细分析,进一步对矿体的空间展布,围岩蚀变,矿化特征,控矿因素等矿体特征进行研究,最后对矿区找矿标志与资源远景评价进行综合研究,对以后的工作具有十分重要的参考价值。

The tectonic location of the old bay mining area belongs to Qinling Mountains fold system, Tongbai Dabie fold belt, Qinling Mountains District, Tongbai Dabie area.On the north slope of Tongbai mountain is one of the famous Chinese mineralization concentrated area, they have cluster belt distribution characteristics. This paper of mining strata characteristics, structural characteristics of detailed analysis and further the spatial distribution of ore body, wall rock alteration, mineralization features, control factors of mineralization etc. ore body characteristics were studied, finally to the mining area for prospecting and resources prospect evaluation of comprehensive study, for future work has very important reference value.
