| 摘 要： | 本文应用单元递归法和分形丛集分析方法对浙江３个不同区域范围内６２９个萤石矿床（点）的空间及储量数据进行统计分析，提示了这些矿床在空间上遵循分形丛集分布，在０．５～１５ｋｍ尺度内具有较一致的分维数，分别为０．５３９、０．５５２和０．４０５，表明这些矿床尽管成矿地质环境及赋矿岩性没相同，但可能有着同一的成因机制；萤石矿床丛集分布形成的密集区的空间尺度为２５０ｋｍ＾２左右。在矿产勘查中可以依据这一尺度来

| Abstract: | This paper has applied the cell- recurrence method and fractal box- counting method to the statistical analysis of 6 2 9fluorite deposits or ore spots in three different areas of Zhejiang Province.The authors have reached the following conclusions:( 1 ) All fluorite deposits in three areas are exclusively in fractal clustering distribution in space and have fairly similar fractal dimensionalities ( 0 .5 39,0 .5 5 2 and 0 .40 5 respectively) ,implying that,though dif- ferent in ore- forming geological environments and host rocks,these fluorite deposits might have been controlled by a general ore- forming mechanism.( 2 ) The densely mineralized area of cluster distribution is spatially characterized by about 2 5 0 km2 .In mineral exploration, this technique will contribute to establishing optimum exploration network,which is eco- nomical and can surely detect important deposits |
