蔡凹锑矿床位于北秦岭加里东造山带内,产于古元古代秦岭群地层中,严格受区域性大断裂和界岭复式背斜两翼的次级褶皱和断裂控制。文中从分析成矿地质背景、矿床地质特征和矿床成因入手,总结了矿床的控矿因素,认为该矿床受含矿地层、构造和岩浆岩等因素控制;提出了新的找矿方向,认为蔡凹锑矿床深部仍有较大的找矿潜力,围绕有利的构造部位和矿化蚀变标志追索矿体,实现找矿勘查的突破。
蔡凹銻礦床位于北秦嶺加裏東造山帶內,產于古元古代秦嶺群地層中,嚴格受區域性大斷裂和界嶺複式揹斜兩翼的次級褶皺和斷裂控製。文中從分析成礦地質揹景、礦床地質特徵和礦床成因入手,總結瞭礦床的控礦因素,認為該礦床受含礦地層、構造和巖漿巖等因素控製;提齣瞭新的找礦方嚮,認為蔡凹銻礦床深部仍有較大的找礦潛力,圍繞有利的構造部位和礦化蝕變標誌追索礦體,實現找礦勘查的突破。

Caiwa antimony deposit in Shanxi province locates in the northern Qinling Caledonian fold beit. It oc-curred in metamorphic rocks of Proterozoic Qinling group, and is strictly controlled by secondly folds of regional fault and faults of Jieling anticlinorium. Based on comprensive analysis of metallogenic geological setting, geological characteristics and the origin of deposit, ore-controlling factors of this deposit have been summarized. It is regar-ded that the Caiwa antimony deposit are obviously controlled by ore-bearing strata, faults and magmatism. New prospecting direction is proposed. It is inferred that there is prospecting potentiality in the deep part of Caiwa anti-mony deposit. Based on favorable faults position and the ore prospecting indicators of mineralization and alteration, new orebodies can be found and a great breakthrough in ore prospecting can be gained.
