| 摘 要： | 根据浙江293个有开采价值的中生代热液萤石、金、银和铅锌矿床数据,在矿床地质研究基础上探讨了这些矿床的空间和储量分形问题。研究表明,在两个尺度范围内,矿床在空间上呈分形分布,其中群集分布的分维数D分别为0.1405-0.3778(1-20km)和0.7168-1.1851(20-750km);密度分布的分维数D分别为0.294-1.1242(1-40km)和0.135-0.252(40-750km)。研究还发现矿床的频度-大小分布也是分形的,其储量分形分布的分维数为萤石(浙江)D=2.34萤石(中国)D=2.13:铅锌(浙江)D=2.27;银(浙江)D=1.63:金(浙江)D=1.09。

| Abstract: | Bascd on data of 293 Mesozoic hydrothermal fluorite, gold, silver and lead-zinc cxploitablc orc dcposits in Zhejiang Provincc and combincd with gcological investigations,the paper studies the spatial distribution of these deposits, discussed fraetat distributions in two scale ranges.The fractal dimension of fractal clustemng is 0.1405 to 0.3778 from 1 to 20 km and 0.7168 to 1.1851 from 20 to 750 krn; the fractal dimension of density distribuhun is 0.294 to 1.1242 from 1 to 40 km and 0.135 to 0.252 from 40 to 750km.The paper also suggets that frequency-size disirbutions for these deposits are a fractat relation: the respective fractal dunensions for the reserves distribution are 2.34 for fluorite (Zhejiang),2.13 for fluorite (China),2.27 for lead-zinc (Zhejiang),1.63 for silver (Zhejiang) and 1.09 for gold (Zhejiang). |
