Реферат: | eng: Study of the magmatics in the Nakyn kimberlite field, with consideration of the isotope dating results, allowed us to establish a sequence of their formation. First, 368.5-374.4 Ma ago intrusions of the Vilyui-Markha dike belt formed. Then (363-364 Ma) intrusion of kimberlites took place. In the Early Carboniferous (338.2-345.6 Ma), alkaline basaltic magma intruded through faults controlling the kimberlites. The magmatic activity finished 331-324.9 Ma ago with the formation of explosive breccias. It has been found that the Nyurba kimberlite pipe consists of two bodies: their kimberlite melts have successively intruded through independent channels.
