摘要
应用分形理论和方法对个旧锡矿遥感信息进行了定量化研究。结果显示,在格子边长为1.4~4.5km的标度范围内,其遥感蚀变和断裂构造进入的总格子数的对数与格子边长的对数均具有很好的线性相关性,表明在研究标度范围内,各子区遥感线性与蚀变信息具有良好的统计自相似性和分形特征。在此基础上,以19号区和26号区为例,分析并进一步探讨了遥感信息分形特征的成矿意义。
Applying fractal theory and method to the quantitative research of the remote sensing information from the Gejiu Sn deposit, the results have shown that there is a perfect linear relativity between the logarithm of the total amout of the lattices which have remote sensing alteration and fracture structure involved and that of the lattices' side length in the case the lattice's side length is in the scale of 1.4~4.5km, which indicates that in the studying scale, the remote sensing linearity and alteration information of each subinterval have excellent statistical self-similarity and fractal characteristics. Based on the former conclusion, the metallogenic meaning made by the fractal characteristics of the remote sensing information has been analyzed and further discussed by taking No. 19 and No. 26 area as examples.
