摘要
黔东南地区金矿的构造控矿特征明显,所有金矿几乎都分布在背斜构造上,控制金矿产出的构造主要有受顺层滑动和切层破裂构造控制的石英脉、断层破碎带和剪切带等三种类型,以剪切带和顺层破裂构造控制的石英脉对成矿最为有利。这些控矿构造与褶皱作用关系密切,有的控制了褶皱的演化,有的为褶皱过程中形成的的次级构造。笔者在系统研究区内金矿控矿构造特征的基础上,分析了各类控矿构造与褶皱的空间关系,建立了金矿控矿构造的空间关系模式。
The structure controlling gold deposits are commonly found in the southeastern Guizhou,most of them distribute in anticlinal structures.There are three major geology units which contain gold,the quartz veins controlled by layer gliding,the fault crushed zones and the shear zones.The quartz veins are the most favorable structure unit for Au mineralization among the three controlling structures.Close correlations are found between ore controlling structures and folds,some ore controlling structures control the evolution of folds,while some are the secondary structures of folds.On the basis of systematical characteristics studies of Au deposit controlling structures in the study area,authors statistically analyze the relationship between the folds and the ore controlling structures,and establish a formation model for ore controlling structures and the anticlinal structures.
