Abstract
Studies on the study of the rocks of the trap formation on the territories of diamondiferous regions within the eastern side of the Tunguska syneclise have been carried out. The zoning of pyroclastic formations of the mafic complex is performed on the basis of the structural-formational analysis in. Volcanogenic rocks formed as a result of explosive processes in the main volume are composed of different-fragmented tuffs. Areal development of pyroclastic formations associated with epicenters of volcanic structures, we reconstructed. This is a negative prognostic factor in the exploration for kimberlites. The regularity of implementation shafts intrusive bodies within the paleo valleys and grabens controlling kimberlites. This is recommended for prediction of new diamond deposits.
