| 摘 要： | 根据板块构造的观点,划分新疆北部地壳的大地构造单元,应用分形基本和分数维的计算方法,计算出新疆北部地壳中金,银,铜的分数维,分析分数维的特征,研究其在板块构造和找矿等方面的意义。元素含量具有分形特征,分数维值的大小和矿化程度有关,最后指出新疆北部的找矿方向。

| Abstract: | Based on the view point of plate tectonics,The tectonic units in the crust of the North Xinjiang can be divided,The basic theory of fractal and calculating method are introduced. The fractal dimensions of Au,Ag,Cu can be calculated, It's range from 1.10 to 1.73,It's characteristics is analysed, The meaning in the plate tectonics and looking for mineral deposits is researched. Element contents of Au Ag Cu have fractal characteristic,thesizes of fractal dimensions have relation to level of mineralization.at last, The potential direction of mineral deposits in the North Xinjiang is pointed out. |
