中文摘要: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，揭示了这些矿床在空间上遵循分形丛集分布，在0.5~15 km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不尽相同，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250 km2左右。在矿产勘查中可以依据这一尺度来制定既经济又不致于漏掉重要矿床密集区的最佳勘查网度，以达到快速逼近潜在矿床密集区的目的。

Abstract:This paper has applied the cell- recurrence method and fractal box-counting method to the statistical analysis of629 fluorite 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 dim ensionalities (0.539, 0.552 and 0.405 respectively), implying that, though different 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 250 km2. In mineral exploration, this technique will contribute to establishing optimum exploration network, which is economical and can surely detect important deposits.
