【摘要】 通过对西峡县杨树沟金矿的矿床地质特征进行详细研究,着重对其成因进行相关研究和对比。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。在该矿区外围还有找这种与剪切带相关的金矿床的巨大潜力。更多还原

【Abstract】 Through detailed study of geological characteristics the gold mineral deposit located in Yangsh-ugou, Xixia county,Henan province,the thesis emphaszes study and comparasion on its cause of formation. Results show that the gold mine is a typical mine 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 will be superimposed, resulting quite a few mineralization types in the same construction zone.There is great potential that related mines can be found.更多还原
