Abstract

The relevance of the discussed issue is caused by the need to study the natural physical fields and their relations with the geological environment. The main aim of the work is to study the magnetic field and the nature of its changes on the typical Siberian sulfide quartz vein gold deposits Darasun. The methods used in the study: specialized experimental methodological field magnetic survey of various observational accuracy and detail of network measurement, laboratory determination of magnetic susceptibility of purposefully selected samples of rocks and ores, statistical analysis of the data, comparing them to known elements of the geological structure of ore-bearing area and its surroundings. The results. The authors have obtained the areal pattern of changes of magnetic induction increment within the ore field of Darasun deposit and its near neighborhood, determined the spectral composition of its changes, magnetic field and relationships with various elements of the geological structure of ore-bearing area Darasun, revealed physical and geological nature of various anomalous zones and provided a basis for assessing the possibilities of magnetic prospecting in solving various geological problems in the stages of prospecting and exploration of quartz-sulphide vein gold deposits in Siberia.
