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.

Unaltered kimberlite of Internationalnaya pipe (Mirny field)
Ores and metals, 2021The porphyry kimberlite block (intrusive coherent kimberlite, after Scott-Smith, 2013) on the deep horizons of the Internationalnaya pipe is characterized by the lack of olivine macrocryst serpentinization, and the minimum degree of postmagmatic alteration in the matrix minerals.

MANTLE XENOLITHS IN THE MATSOKU KIMBERLITE PIPE
Physics and Chemistry of the Earth, 1975Abstract The chemical compositions of selected xenoliths from the Matsoku pipe and many constituent minerals are discussed. It is concluded that the xenoliths form a closely related suite of rocks of differing mineralogy and chemistry which could have been produced during a single igneous event in the mantle. It is likely that at solidus temperatures

Geomechanical conditions of kimberlite extraction in terms of internatsionalnaya kimberlite pipe
Journal of Mining Science, 2009The paper analyzes geomechanical conditions of slicing method application to extract a vertical ore body in terms of Internatsionalnaya kimberlite pipe. The authors assess stability of stopes at principal stages of horizon mining.

Degassing structures in volcaniclastic kimberlite: Examples from southern African kimberlite pipes
Journal of Volcanology and Geothermal Research, 2008Kimberlite pipes are commonly filled with a distinctive structureless facies termed volcaniclastic kimberlite (previously also termed Tuffisitic Kimberlite Breccia, TKB), which constitutes a thorough mix of both juvenile material and lithic clasts derived from all stratigraphic levels.
