摘要:

断裂体系在成矿流体的运移和聚集过程中起着重要的控制作用,是重要的导矿和容矿构造,断裂分维值的大小是断层数量、规模、组合方式及动力学机制的综合体现,可以作为断裂构造复杂程度的一个定量参数。新疆塔什库尔干—莎车一带断裂因素主控了矿(床)点的分布。应用分形几何方法对该区 Ⅰ、Ⅱ-1、Ⅱ-2和Ⅲ各成矿区带断裂进行了研究,表明其断裂分布具有自相似性,断裂分数维值分别为1.49、1.33、1.34和1.22,成矿有利性量化从大到小依次为Ⅰ>Ⅱ>Ⅲ,各带主攻矿种分别为铅锌铜矿、铅锌多金属矿和磁铁矿。此研究为新疆塔什库尔干—莎车一带区域矿产勘查指明了方向。

Abstract:

The fault system is an important ore-channeling and ore-hosting structure,which plays an important role in controlling the migration and accumulation of oreforming fluid.The fractal dimension value of the fault system is a comprehensive embodiment of the fault amount,scale,assembly pattern and dynamic mechanism. It can be a quantitative parameter to describe the complexity of the fault system.The distribution of ore deposit (occurrences) is controlled by fracture in TaxkorganShache area of Xinjiang, and the fractal geometry study of the Ⅰ,Ⅱ-1,Ⅱ-2 and Ⅲ metallogenic districts indicated that these fracture systems possess the well statistical selfsimilar character,and the fractal dimension value were as follows: 1.49,1.33,1.34 and 1.22. The quantitative ordination of the metallogenic potential in this area isⅠ>Ⅱ>Ⅲ,and the target ores of the meta llogenic districts are leadzinc-copper deposit,leadzinc polymetallic deposit and magnetite.This study points out the orientation of prospecting in Taxkorgan-Shache of Xinjiang Uygur Autonomous Region

Key words: fault, fractal characteristic, Taxkorgan-shache area of Xinjiang, ore-prospecting prediction
