Estimation of fractionation of minerals using geoinformation systems in engineering and geological prospecting

Abstract

The article discusses the use of geographic information systems in the study of kimberlite deposits in order to establish diamondiferous content based on indicator minerals, in particular olivine. It investigates the distribution of olivine in different zones of the kimberlite deposit and establishes a relationship between its characteristics and the presence of diamonds. Methods for analyzing geological data using Golden Software Surfer software are used to visualize the relief and distribution of minerals. A method of application of geographic information systems for the analysis of the results of research on the determination of the diamondiferous content of kimberlite by the presence of minerals-indicators of kimberlite and their properties is proposed. With the help of Google Earth Pro software, the location of the deposit in two-dimensional space is determined and converted into a three-dimensional coordinate system using the Golden Software Surfer program. A database is formed based on the results of geological exploration on the concentration of a certain mineral and its particle size distribution along the length of the well. A 3D visualization of the distribution of olivine grains in wells has been created in order to establish the relationship between the size of olivine and the number of diamonds mined. The conclusions of the article emphasize the importance of further research for a better understanding of the processes of formation of kimberlite deposits and the development of effective methods for forecasting diamond production. Estimation of diamond resources and analysis of the relationship between olivine grain size and diamond production demonstrate the need for further research to understand the formation processes of kimberlite deposits.
