| 摘 要： | 基于分形理论,提出了一种快速测量多区断裂分维值的方法,并获得了研究区断裂分维值的平面等值图。研究结果表明,断裂分维值的大小较好地反映了断裂构造复杂程度的高低,它们之间存在着正相关关系。研究区花岗岩型铀矿田内约有86%的铀矿床位于断裂分维值D偏高(D>1.18)的区域内,表明断裂分维值越大,越有利于花岗岩型铀矿成矿,为建立该区花岗岩型铀矿新的预测标志提供了参考依据。

| Abstract: | Based on fractal theory, one kind of fast method of measuring fractal dimension of fault is presented in this paper. In addition, plane contour map showing fractal dimensions of faults in study area is obtained with fast measuring method mentioned above. It is shown that magnitude of fractal dimension is proportional to the complexity of faults. More than 86% of known granite-type uranium deposits in the study area are located within the zones with fault fractal dimension greater than 1.18. A conclusion can... |
