Abstract

Summary

During the search of kimberlite pipes at the Anabar Shield (Yakutia, Russia) a three-dimensional (3D) inversion of nonstationary electromagnetic fields was used. Registration and processing of data were performed by an electromagnetic sounding and induced polarization (EMS-IP) technology, which is based on the calculation of normalized transient processes from 10 mcs to 125 ms. It is shown that 3D modeling together with EMS-IP technology may be used to separate such objects as diatreme (characterized by increased polarizability and deep lower boundary) from magnetic anomalies coincident with conduction abnormalities, but not related with non-indigenous objects such karst cavities, sulfides in sediments, etc. The methodological works were carried out in the search of kimberlite pipes in the kimberlite fields of Kuonapskaya group and Kelimyar area (Olenek area) in Bulun district of Anabar Shield (Yakutia, Russia).
