| 摘 要： | 利用分形理论中的盒式分维探究新疆东天山康古尔塔格金矿带构造及金矿床的空间分布，得出两者在空间上具有双重分形的特点。结合前人的研究成果，认为研究区在区域上是韧性的剪切带，而在局部体现为脆性地质体，金矿的分布在一定范围是随机的，但在区域上受韧性剪切带的控制，呈带状或线状分布，更为重要的是线性构造与金矿可能是同一时期同一构造运动的结果。在区域上，脆韧性剪切转换带是金矿的有利成矿部位。

| Abstract: | Using the box-counting dimension method of fractal theory, the authors investigated the spatial distribution of structures and gold deposits in the Kangguertage gold ore belt within the East Tianshan Mountain of Xinjiang and have reached the conclusion that they have double-fractal characteristics. In combination with previous researches, the authors hold that the study area is regionally a ductile shear zone but locally a britele geological body. The distribution of gold deposits is random in a limited area but is regionally controlled by the ductile shear zone and assumes banded or linear arrangement. It should be pointed out that the banded structure and the gold deposits might be products of the same geological period and the same tectonic movement. The transitional place of the ductile-brittle shear zone is the favorable position for gold mineralization. |
