陕西省丹凤县蔡凹锑矿床地质特征及找矿方向

Geological Characteristics and Prospecting Direction of Caiwa Antimony Deposit in Danfeng County in Shanxi Province

摘要:

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。

Abstract:

Caiwa antimony deposit in Shanxi province locates in the northern Qinling Caledonian fold beit. It occurred 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 regarded 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 antimony 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.
