The geochemistry and geochronology of Tanzanian kimberlites [PDF]
, 2012 © 2012 Dr. Rachel CheslerThe Tanzanian Craton is host to numerous kimberlite intrusions, although few have been studied in any detail. Due to its proximity to the East African rift zone, this region also provides a unique opportunity to investigate the ...

Identifying critical parameters in the settling of African kimberlites [PDF]
, 2017 Kimberlite is the host rock of diamonds and varies widely in geological and mineralogical features as well as color, processing capability, and dewatering characteristics. This study investigated the dewatering behavior of problematic Angolan kimberlites.
