Gold ore deposits located in black shale strata are one of the main industrially significant sources of ore gold. However, using geophysical methods for exploration of these objects may lead to numerous problems caused, on the one hand, by relatively low physical contrast and, on the other hand, by the distorting effect of graphitized rocks. This article presents some insitu geophysical data from a promising area in Bodaibinsky region, their analysis and some basic conclusions.
The complex copper-porphyre deposits constitutes the significant portion of the World’s and Russian gold reserves. The application of petrophysical and physico-geological models can increase the interpretation efficiency of data obtained in prospecting and exploration for copper-porphyre deposits. The paper presents the results of Ak-Sugskoe field geophysical survey and final conclusions based on the result analysis.
The study of golden ore deposits is rather complicated problem. The main ways to rise effectiveness of these studies are improving methods of analyzing physical fields’ structure and finding connections between their morphology, zoning and golden ore bearing. The materials of studying of Tardanskoe golden ore cluster using electroprospecting methods, analysis of these investigations and conclusions, based on the results of this analysis are presented in this article.
Golden ore objects are rather difficult object for researching them by geophysical methods. The analysis of efficiency of using the electroprospecting methods in the researching different kinds of Siberian golden ore deposits was taken. There was also made a conclusion that for the rising of efficiency of the methods using for the researching of golden ore deposits they are needed to be pointed at the revealing of petrophysical and geophysical zonality, which is individual for each kind of golden ore deposits.
