SDLRC: Brooke Clements highlights technical diamond articles for September 2019

Sheahan Diamond Literature Reference Compilation
The Sheahan Diamond Literature Reference Compilation is compiled by Patricia Sheahan who publishes on a monthly basis a list of new scientific articles related to diamonds as well as media coverage and corporate announcements called the Sheahan Diamond Literature Service that is distributed as a free pdf to a list of followers. Pat has kindly agreed to allow her work to be made available as an online digital resource at Kaiser Research Online so that a broader community interested in diamonds and related geology can benefit. The SDLRC Blog is a guest commentary by an industry expert about articles, themes and trends in recent issues of the SDLRC.

Technical Articles
The kimberlite factory: the volcanic nature of kimberlites. Andrews, ID This GSA abstract describing kimberlite emplacement is a nice read.
Mantle terranes of the Siberian craton: their interaction with plume melts based on thermobarometry and geochemistry of mantle xenocrysts. Ashchepkov et al., ID A read of the abstract suggests that this 48 page paper would be valuable for those in industry and academia interested in mantle terranes.
Structural and mineralogical features of diamonds from the Lomonosov deposit (Arkhangelsk Province): new data and interpretation. Kriulina et al., ID A study of diamonds from Lomonosov shows there are three types present.
Subsurface structural mapping using EIGEN6C4 data over Bundelkhand craton and surroundings: an appraisal on kimberlite/lamproite emplacement. Kumar and Kumar, ID This study examines the link between a group of kimberlites and underlying regional structures in India.
The composition of the lithospheric mantle beneath the Karowe Mine and its associated diamond sources in north-eastern Botswana. Motsamai, ID This comprehensive study of the lithospheric mantle done at the U of Alberta is a free download. The author combines study of mantle xenoliths, cpx xenocrysts, diamond inclusions and the physical and chemical charactersitics of some diamonds to put together a lithosphere model. The lithospheric mantle is modelled to be 210 km thick with a 90 km thick diamond window.
Rubies from Rock Creek, Montana. Potentate Palke and Hapeman, ID Rubies are rare in North America. To date, 29 rubies have been recovered from the Rock Creek sapphire mine in Montana. The rubies were only recovered after miners were asked to put aside what they thought were garnets which suggests they could be more commonly associated with sapphires than previously thought.
