Experimental work using the gravimetric method at iron ore deposits of the Kola Peninsula

Abstract

In the summer of 1933, the gravimetric team of the Scientific Research Sector of the Leningrad Mining Institute carried out experimental work using the gravimetric method on the iron ore deposits of the Kola Peninsula in the Zaimandrovskii region. The results of work using the gravimetric method show that this method gives excellent results when working in the area of ​​iron ore deposits of the Kola Peninsula, despite the extremely difficult working conditions due to the highly developed topographic surface relief, the influence of the underground relief of bedrock, the heterogeneous structure of glacial deposits and the technical difficulties of making observations in conditions of the north. The gravimetric exploration method in combination with magnetometric and pit-hole operations provides great opportunities for both geological detailed mapping and the search for rich hematite ores.
