Application of Medium-Scale Magnetotelluric Sounding to Identify Deep Criteria for Promising Areas for Kimberlite Exploration

摘要

Medium-scale magnetotelluric sounding conducted within the Malaya Botuobiya (Yakutian dia-mondiferous province) and Zimnii Bereg (Archangelsk diamondiferous province) kimberlite regions revealedthe main features of their geoelectric sections. These features have a genetic relation to the processes of kim-berlite formation. All of the known kimberlite pipes of the two regions are located within the outlines of therevealed conducting geoelectric heterogeneities. The presence of such heterogeneities can be regarded as a pos-sible deep criterion for distinguishing promising areas for kimberlite exploration.
