摘要:

龙门店银矿断层发育,主要有NE、NW和NNE向3组断裂,其中NE和NNE向断裂与成矿关系密切,矿体的形成与分布严格受断裂控制。为研究断裂分维特征与矿体的关系,采用计盒维数法计算出龙门店银矿断裂的分维值为1.295,中部分维值为1.319,性质偏于剪性;与成矿有关的NE-NNE向断裂在全区和矿区中部的分维值分别为1.197和1.237,为剪性断裂。二者判定系数R2均>0.98,说明矿区断裂具有良好的自相似性。与成矿相关的NE-NNE向断裂分维值D>1.17所圈闭的太华群片麻岩是有利的成矿部位,全区断裂分维值D>1.25作为辅助指标。采用分维值定量描述断裂的自相似性,对成矿预测有一定的指导作用。

Abstract:

 Faults development at the Longmendian silver mine was mainly characterized by the NE,NW and NNE trending fractures,in addition,the NE and NNE trending fractures were closely related to mineralization.Namely,the formation and distribution of the ore bodies were controlled by fracture strictly.For the purpose of studying fracture fractal characteristics and the ore body,the box-counting dimension method was applied to calculate the fracture fractal dimension value (1.295)at the silver mine,and the value in the central area was approximately 1.319 with shear fracture.Fractal dimension values of the NE-NNE trending fracture with shear fracture related to mineralization at the whole and central regions were 1.197 and 1.237,respectively.The determination coefficient R2 was greater than 0.98,suggesting that the fractures at mining area had a good self-similarity.The NE-NNE trending fracture fractal dimension value(D>1.17)related to mineralization,and the trapped Taihua group gneiss was favorable metallogenic area.The fracture fractal dimension values D>1.25 at the whole reinog was as auxiliary index.The self-similarity was determined by fractal dimension value of quantitatively in this study,which functioned as guiding for the metallogenic prediction.

Key words: fractal dimension value, fracture structure, fractal characteristic, Longmendian silver mine, Henan Province
