Possibilities of the AMTS when searches of kimberlite pipes in complicated geological conditions

An analysis of kimberlite pipes structure and induction logging data shows that the most conductive parts of the pipes are the roots, built by porphyric kimberlite. Investigations using the audiomagnetotelluric sounding method on pipes Geohimicheskaya and Zarja have shown that the most contrasting anomalies exist for deep intervals of cross-sections from 250-300 to 600 m. The obtained results show an inclined deposition of the pipe Geohimicheskaya and more complex in comparison with available data structure of the pipe Zarja (presence of several roots). The electromagnetic sounding methods with the depth of investigations of 600-800 m are the most perspective at searches of kimberlite pipes in complicated geological conditions.
