Cole-Cole模型参数在时间域激电找矿中的应用
The application of Cole-Cole model parameters to the time domain induced polarization prospecting
摘要
Abstract
the routine time domain induced polarization can only obtain two parameters,i.e.,resistivity and polarizability,which often makes it difficult to accurately interpret induced polarization anomaly and thus causes less information for orebody interpretation and poor detection resolution. Such a phenomenon is especially prominent in the exploration of some ore resources characterized by associat-ed or accompanying minerals like carbonaceous limestone, pyrite and limonite whose resistivities or polarizabilities are close to each other. In order to enrich orebody geological information, improve the understanding of orebody and reduce mistaken or incomplete judgement,the authors utilized the feature that Cole-Cole model could describe time response of induced polarization effect and em-ployed damping least squares method to realize the best fitting of the time response with time domain Cole-Cole model so as to obtain varied kinds of Cole-Cole model parameters. Practice shows that this method is economical and effective and,through integrated inter-pretation of varied kinds of physical parameters,it can realize more overall understanding and correct induction and interpretation of in-duced polarization and also improve the resolution of the time domain induced polarization in deep prospecting.关键词
