Diamonds and the geology of Earth mantle carbon

2012
Diamond can crystallize throughout the mantle below about 150 km and while it exists metastably in the crust, it is the only material sampling the ‘very deep’ mantle to depths exceeding 800 km. Diamond has been intensively studied over the last 40 years to provide extraordinary information on Earth’s deep interior.

Geology, Mineral Chemistry, and Structure of the Kimberlites at Diavik Diamond Mine: Indicators of Cluster-Scale Cross-Fertilization, Mantle Provenance, and Pipe Morphology

2018
Abstract The Diavik diamond mine includes four diamondiferous kimberlite pipes (A154N, A154S, A418, and A21) and minor kimberlite dikes that are mined by Rio Tinto and Dominion Diamond Corporation. Pipe morphologies from A154S, A154N, and A418 show similar circular near-surface expressions, with expansion of cross-sectional area and ...
