Mapping of intrusive massifs in the northern part of the Balygychan-Sugoi Trough (Magadan Region) based on geophysical data

The article presents methods of processing and interpreting materials of the integrated airborne geophysical survey (magnetometry, gamma-spectrometry) at a scale of 1:50,000 for mapping intrusive massifs as exemplified in the northern part of the Balygychan-Sugoi Trough. The author specified contours of known massifs, for the first time identified unexplored granitoid formations, as well as a series of dikes and minor intrusions. The presented results of modeling and classification of potential geophysical fields allowed exploring the deep structure of the massifs. Geophysical data indicating different petrophysical properties of rocks helped to divide intrusive formations. The article classified the massifs by complexes, each of which is promising for gold, silver, and tin mineralization.
Keywords: mapping, intrusive massif, Balygychan-Sugoi Trough, anomalies of geophysical fields, petrophysical modeling.
