【摘要】 甘肃礼县佐家锑矿大地构造位置为秦岭印支褶皱带。其北以毛羽沟-寺顶山-江洛镇大断裂与华力西褶皱带相邻,南以银洞湾-铁家山-沈家院-秦家坝大断裂与加里东褶皱带接壤。矿体赋存于上三叠系三渡水组第二层(Ts^3-2b)粉砂岩、细砂岩、角砾岩、硅质白云质灰岩夹板岩中。受近东西向断裂破碎带控制。文章在总结了成矿地质背景及地质特征的基础上,提出了找矿标志。更多还原

【Abstract】 The Zuojia antimony in Lixian county, Gansu province, is located in the geotectonic location is the Qinling indosin fold beltlead.The north is bordered by the Maoyugou-Teodingshan-Jiangluo town fault and the Hualixi fold belt. The south is bordered by the Yindongwan-Tiejiashan-Shenjiayuan-Qinjiaba fault and the Caledonian fold belt.The ore body is located in the second layer(Ts^{3-2 b}) siltstone, fine sandstone, breccia and siliceous dolomitic limestone plywood of the Upper Triassic Sandu Formation. Controlled by the near-east-west fault fracture zone. Based on the summarization of ore-formation geological settings and geological features, some ore prospecting indicators are given in the essay.更多还原
