results of large-scale ground magnetic survey on the broknes peninsula (larsemann hills, princess elizabeth land, east antarctica)

In the course of seasonal work of the 70th russian antarctic expedition (rae) in 2024-2025, as part of the field geological and geophysical studies by researchers of empress catherine ii saint petersburg mining university on the broknes peninsula (larsemann hills, east antarctica), areal ground magnetic survey was accomplished at 1:10,000 scale. the study area is characterized by a high exposure degree of cambrian and precambrian rocks with localization in certain parts of magnetite-bearing complexes. the work included experimental and methodological research, surveying in two modes (discrete and continuous) with data quality control as well as subsequent processing and initial interpretation of the results. a detailed map of the total magnetic intensity covering an area of 17.5 km2 and maps of the field transformations – vertical derivative, absolute horizontal gradient, etc., were compiled. qualitative interpretation allowed identifying morphologically homogeneous zones in the study area characterized by different features of anomalous magnetic field. results of the studies will be used in future for geological interpretation of anomalies and compilation of the structural tectonic map of the region.
