| 文章根据西藏古堆-隆子地区Sb,Pb,Zn化探元素品位分析结果,结合区域地质资料,基于分形几何学的理论基础,对研究区Sb,Pb,Zn的分布规律进行了定量研究。结果表明,4个研究区Sb,Pb都具有多重分维的性质,且与矿化有关的分维值D2Ⅱ >D2Ⅲ,同一研究区同一元素的各组分维值差距较大,Ⅲ区和Ⅳ区的Zn只有一个维数值,说明典型矿床发育的地区成矿元素具有多重的分维结构和低分维值D2,基于此理论成功验证了恰嘎研究区具有寻找锑矿前景。通过研究Sb,Pb,Zn的分形特征,揭示出化探元素的分维结构和分维值的大小与矿化程度有关,并为找矿勘查工作提供一定的地质依据。 |

| Combined with the regional data distribution regularity of geochemical analysis of Sb,Pb,Zn from the study area is quantitatively studied on basis of fractal geometry theory. The result shows that Sb, Pb of the four study areas are characterized by multi-fractal feature and fractal dimension value D2Ⅱ>D2Ⅲ is correlated to mineralization showing bigger difference of fractal dimension value of the same element for each groups in the same study area. Zn has only one fractal dimension value of study area Ⅲ and IV. All this indicates that the area where typical ore deposit occurs is characterized by multi-fractal feature and low fractal dimension value D2. According to the theory Qiaga study area is checked potentiali for prospecting Sb ore. Fractal feature of Sb, Pb, Zn shows that structure of the fractal dimension and its value are related to degree of the mineralization thus provide geological basis for prospecting works. |
