【摘要】 对山西省堡子湾隐爆角砾岩型金矿床钻孔岩芯的金品位进行了分形研究 ,其变化符合以分维值 D为特征的幂律分布。在垂向上 ,金品位的分维值由角砾岩体上部到下部逐渐增大。在平面上 ,分维值由南向北逐步减小。结合浅层地震勘探与坑探、钻探显示的角砾岩体结构特征、矿体赋存部位以及地表构造现象 ,讨论了金矿品位分维值D的大小与品位的关系 ,提出了矿体可能的空间赋存规律更多还原

【Abstract】 The fractal analysis of gold grades in drill cores from the Puziwan cryptoexplosive gold deposit has been done. The fluctuation of gold grade data conforms to the power law distribution which is characterized by the fractal dimention D. The fractal dimentions of gold grades in the breccia body increase gradually from top to bottom vertically and from south to north horizontally. Combining the result of shallow seismic exploration, the occurring locations of ore bodies, the surface structure and the structural features of the breccia body revealed by drill holes, the relationship between the fractal dimentions of gold grade and gold grade of the deposit has been discussed. The possible spatial distribution regularity of ore bodies has been proposed.更多还原
