摘要: 在建立合理地质模型、力学模型和数学模型的基础上,采用SuperSAP有限元数值模拟方法对胶东招远-平度断裂带中段金矿聚集区成矿期应变能和流体运移势的分布进行了计算,发现应变能的高值区和流体运移势的低值区是成矿的有利构造部位,这些信息对该区寻找深部蚀变岩型金矿体具有重要的指导意义。

Abstract: On the basis of the construction of the rational geological,mechanical and mathematical models,the SuperSAP finite element numerical modeling is used to study the spatial distribution of the syn-mineralization strain energy and fluid migration potential of a gold deposit cluster in the central segment of the Zhaoyuan-Pingdu fault,Jiaodong area.The results show that the area with high strain energy and low fluid migration potential is likely to a favorable structural site for ore deposition.This information has great significance for guiding deep alteration-type gold exploration in the Jiaodong area.
