对新疆阿尔泰地区 175个热液金、铜、铅、锌、稀有金属矿床的研究表明 ,该区矿床的空间分布为多重分形分布。在 q=- 2～ 14范围内 ,标度指数为 - 5.4 915～ 12 .80 71,奇异指数 a( q)随 q值变化较大 ,为 0 .92 4 8～ 2 .2 865,分维谱具单峰曲线特征。q=0时 ,在 1～ 150 km尺度范围内出现二个分形关系 ,在 1～ 16km尺度范围内 D0 值为 0 .2 3,在 16～ 150 km尺度范围内 D0 值为 1.51。导致该区矿床多重分形分布的主要原因是在不同尺度下矿床的形成控制机理的不同和矿床的勘探研究程度较低 ,该区还有较大的找矿前景。
A study of 175 hydrothermal gold, copper, lead, zinc and rare metal deposits in the Altay region of Xinjiang shows that the spatial distribution of ore deposits in this area is multifractal. In the range of q = -2 ~ 14, the scale exponent is-5.4 915 ~ 12 .80 71, the singular exponent a (q) changes greatly with the value of q, which is 0.92 4 8 ~ 2. Spectral unimodal curve characteristics. When q = 0, there are two fractal relations in the scale of 1 ~ 150 km, D0 value of 0.23 in the range of 1 ~ 16km and D0 of 1.51 in the range of 16 ~ 150 km. The main reason for the multifractal distribution of ore deposits in this area is the difference in the control mechanism of deposit formation and the low level of prospecting exploration in different scales. There is also a great prospect for prospecting in this area.
