Comparative Study of the Kimberlites of Bakwanga (North Group) and Bakwa-Kalonji (South Group) In East Kasai, Democratic Republic of Congo.

Analecta
The presence of kimberlites in the Democratic Republic of Congo has been known since buttgenbach reported a typical ‘yellow ground’ in Katanga as early as 1908, and prospecting work before and after 1914 had already identified twenty-four pipes in ...

Petrophysical characteristics of geological-geophysical models of kimberlite pipes of the Archangelsk' kimberlite province

RUDN Journal of Engineering Research, 2008
The results on physical properties of naturally hosting rocks and kimberlites of Arkhangel'sk diamondiferous province are considered. Geologic-geophysical model of diamond deposits of the considered field has been constructed.

Thermal State and Thickness of the Lithospheric Mantle Beneath the Northern East-European Platform: Evidence from Clinopyroxene Xenocrysts in Kimberlite Pipes from the Arkhangelsk Region (NW Russia) and Its Applications in Diamond Exploration

Geosciences
This paper presents the reconstruction of the architecture of the lithospheric mantle, including its thermal state and thickness, as well as the scale and efficiency of its sampling by four kimberlites from the Arkhangelsk diamondiferous province ...
