杨树沟金矿床地质特征及成因探讨

Geological characteristic and genesis of Yangshugou gold-bearing deposit

通过对西峡县杨树沟金矿的矿床地质特征进行详细研究,对其成因进行了相关研究和对比。结果表明:杨树沟金矿是典型的与剪切带相关的金矿床。早期受到韧性剪切带作用,随后韧性剪切带经抬升剥蚀构造层次上移,叠加后期的韧—脆性、脆性变形,成矿作用也随之叠加,从而在同一构造部位出现多种矿化类型。在该矿区外围,还有查找这种与剪切带相关的金矿床的巨大潜力。

Through detailed study on deposit geological characteristics of Yangshugou Gold Mine,Xixia county,the cause of formation was studied and compared.Results showed that the gold mine was a typical gold-bearing deposit related to shear zone.In its early period,it was affected by ductile shear zone.As time went by,the shear zone was lifted up and denuded,and its construction layers went up.Superimposed late brittle-ductile,brittle deformation,mineralization also superimposed,resulting quite a few mineralization types in the same construction zone.There was great potential for searching gold-bearing deposit related to shear zone around this mine area.
