Diamondiferous kimberlite in Saskatchewan, Canada - a biogeochemical study

, 1993
Kimberlite was first reported in Saskatchewan in 1988. Subsequently, more kimberlite pipes have been discovered and the total diamond yield is now 160, of which some are macro-diamonds of gem quality.

New identity of the kimberlite melt: Constraints from unaltered diamondiferous Udachnaya-East pipe kimberlite, Russia

, 2011
Kimberlite magmas are in many aspects unusual compared to other terrestrial magmatic liquids. They are very rare and occur in small volumes, but their intimate relationships with diamonds make them invaluable to the scientific and exploration communities.

A practical guide to terminology for kimberlite facies: A systematic progression from descriptive to genetic, including a pocket guide

, 2009
Kimberlite terminology remains problematic because both descriptive and genetic terms are mixed together in most existing terminology schemes. In addition, many terms used in existing kimberlite terminology schemes are not used in mainstream volcanology,

Kimberlite Crystallization and Emplacement Through the Lens of Mantle-Derived Ilmenite and Chromite

Kimberlites, the primary hosts of diamond deposits, are enigmatic igneous rocks derived from the mantle and emplaced into cratons. There is still limited understanding of their origin and formation.

Petrography, mineralogy, geochemistry and geochronology of the diamondiferous Drybones Bay kimberlite Pipe and Mud lake kimberlite dyke, Northwest Territories

, 2016
The Drybones Bay and Mud Lake kimberlites are Ordovician kimberlites located in the Slave Geological Province. The Drybones Bay pipe formed by multiple discrete eruptions, producing several texturally distinct phases of kimberlite, including hypabyssal ...

Some major problems with existing models and terminology associated with kimberlite pipes from a volcanological perspective, and some suggestions

, 2008
Five significant problems hinder advances in understanding of the volcanology of kimberlites: \ud \ud (1) kimberlite geology is very model driven; \ud \ud (2) a highly genetic terminology drives deposit or facies interpretation; \ud \ud (3) the effects ...
