深部矿体定位预测的构造优势线法——以夏甸金矿区Ⅶ号脉为例

Approach of structural advantage lines in the location prediction of deep orebody —with vein Ⅶ in Xiadian gold orefield as an example

以山东夏甸金矿区Ⅶ号脉为例,基于矿区构造特征、控矿构造标志和控矿构造演化等多方面研究,提出深部矿体定位预测的构造优势线法。该构造优势线法的核心思想是将已有的富矿体、矿化带单体、矿化带和工业矿体通过分形理论进行模拟,以期达到深部矿体定位预测的目的。实践表明,构造优势线法特别适用于典型受多期次构造复合控制的矿体,在深部矿体定位预测中效果显著。

Geological structure has been the key point and difficulty in deep prognosis for hydrothermal deposit. Taking vein Ⅶ in Xiadian gold orefield as an example and based on the research of structural features, ore-controlling structural signs and evolution, a structural advantage line approach for the location prediction of deep orebody was proposed. The core idea of＇ this method is that oreshoot, mineralization belt monomer, mineralized zone and industrial ore bodies are simulated by the fractal theory to achieve location prediction of deep orebody. The practice shows that this method is especially suitable for typical muhi-stage structure controlling orebody and the location prediction of deep orebody proves to be effective.
