Conditions of localization and criteria for kimberlites exploration (on the example of Igyatta diamondiferous region, Western Yakutia)

Abstract

The main source of mined diamonds in Russia is the Yakutia diamond-bearing province (YAP). To date, all open areas within the prospective Vilyuy-Markha deep fault zone (VMZ) of the YAP, which is a mineragenetic and which hosted diamond deposits of Mir, International, Nyurbinskaya, Botuobinskaya, have been studied satisfactorily. It is unlikely to reveal new kimberlite fields within its' opened part. In this case, the presence of direct signs of new objects beneath the Mesozoic-Cenozoic strata indicates that the diamond potential of the territory is not exhausted. This was confirmed by the discovery in 2015 of a kimberlite body in the Suldyukar field, which confirmed the presence of the Igyatta diamondiferous region and allows us to view the overlapped areas of the VMZ as the most promising for discovering of the new deposits. However, the search for buried deposits requires improvement of the criteria.
