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
