KIMBERLITE SILLS AND DYKES ASSOCIATED WITH THE WESSELTON KIMBERLITE PIPE, KIMBERLEY, SOUTH AFRICA [PDF]
South African Journal of Geology, 2012 Field relations, petrography and bulk rock geochemistry constrain the emplacement mechanisms and petrogenesis of a kimberlite sill complex exposed in water tunnels at Wesselton Mine, Kimberley. The sill complex, together with associated dykes, is precursor to the main Wesselton pipe and contains: 1.

Abiotic polycyclic aromatic hydrocarbons originating from the sub-oceanic mantle [PDF]
Scientific ReportsExperimental studies have demonstrated that petroleum may form from abiotic organic compounds synthesised in the Earth’s upper mantle. However, the most direct evidence of mantle-derived organics, as obtained from whole-rock analyses, indicates ambiguous

Diamonds from low-grade kimberlite
Руды и металлы, 2022 Based on exploration and sampling work on the Siberian platform (SP) the uneven diamond content of various diatremes was established. During the exploration apart from the pipes with high or medium content of a useful component also the diatremes with ...

Geotechnical Modelling for Kimberlite Pipes [PDF]
Proceedings of the First Southern Hemisphere International Rock Mechanics Symposium, 2008 EKATI Diamond Mine is located some 200 km south of the Arctic Circle and 300 km northeast of Yellowknife in the Northwest Territories of Canada. It is a remote fly-in-fly-out site with road access limited to the winter ice road season. The operation currently consists of two active open pits and two underground operations.
