Abstract

Structural geological and tectonophysical studies at a qualitatively new methodical level in the Yubileinaya pipe open pit have shown that the fault-block tectonics plays substantial role in the spatial localization of kimberlite bodies. It has been established that localization of diamond-bearing kimberlite pipes is controlled by faults, which are expressed in the platform cover as wide, complexly built zones with a high density of local faults and tectonic fractures. As follows from 3D representation of data and analysis of stress fields, tectonic movements during kimberlite emplacement had shear kinematics. A tectonophysical model of local control of kimberlite bodies by fault-line extensional structural elements (pull-apart fissures and duplexes) has been elaborated.
