Abstract

Electrical geophysical prospecting methods are widely used at different stages of geological exploration. In the last two decades, new computer technologies and satellite navigation systems were successfully introduced in the geophysical industry. As a result, exploration technologies have improved, and new geophysical methods have been developed, such as electrical resistivity tomography (ERT) and spectral induced polarization (SIP) methods. An important role in ore geophysics is played by magnetotelluric (MT) methods. In this article, we focus on the issues of methodology and interpretation of electrical prospecting data for solving ore exploration problems. Special attention is paid to the induced polarization (IP) method that is most widely used in mineral exploration and mining industry as one of the most important and most dynamically developing techniques of ore geophysics. In addition, the issues of correct choices of survey scales and the use of automatic 2D and 3D inversion programs are considered.

电物探方法在矿床勘查中的几个问题

电物探方法广泛应用于地质勘查的不同阶段。在过去的二十年中，新的计算机技术和卫星导航系统成功地引入了地球物理工业。因此，勘探技术得到了改进，并开发了新的地球物理方法，如电阻率层析成像(ERT)和光谱诱导极化(SIP)方法。大地电磁方法在矿石地球物理中起着重要的作用。本文主要讨论电法找矿资料的方法和解释问题，以解决找矿问题。特别关注的是作为最重要和最动态发展的矿石地球物理技术之一，在矿产勘探和采矿工业中应用最广泛的诱导极化(IP)方法。此外，还考虑了测量尺度的正确选择和自动二维和三维反演程序的使用问题。

期刊介绍： The purpose of the journal is facilitating awareness of the international scientific community of new data on geodynamics of continental lithosphere in a wide range of geolchronological data, as well as tectonophysics as an integral part of geodynamics, in which physico-mathematical and structural-geological concepts are applied to deal with topical problems of the evolution of structures and processes taking place simultaneously in the lithosphere. Complex geological and geophysical studies of the Earth tectonosphere have been significantly enhanced in the current decade across the world. As a result, a large number of publications are developed based on thorough analyses of paleo- and modern geodynamic processes with reference to results of properly substantiated physical experiments, field data and tectonophysical calculations. Comprehensive research of that type, followed by consolidation and generalization of research results and conclusions, conforms to the start-of-the-art of the Earth’s sciences.
