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.

Brooke Clements received a B.Sc in Geology from Indiana University and an M.Sc in Economic Geology from the University of Arizona. From 1982 to 1997, he was an Exploration Geologist and Regional Manager for Exmin Corporation where he conducted diamond exploration programs throughout the United States. From 1998 to 2007 he was Vice President, Exploration for Ashton Mining of Canada Inc. Under his leadership, the Ashton-SOQUEM exploration team discovered the Renard diamond district in Quebec where Stornoway Diamonds opened the Renard Diamond Mine in 2016. From 2007 to 2015 he was President of Peregrine Diamonds Ltd. where he led the team that discovered the Chidliak diamond district on Baffin Island in the Canadian Arctic. Currently, Brooke is President of JBC Ventures Ltd., a consulting company specializing in mineral exploration and community and government relations. He is also President and CEO of Craton Minerals Ltd., a private diamond exploration company focused on discovering North America's next new diamond district.

2019 Yellowknife Geoscience Forum: The Yellowknife Geoscience Forum held every year in November is put on by the NWT government and the Northwest Territories and Nunavut Chamber of Mines. It's a great place to catch up on the latest geology/mining/policy developments in the Northwest Territories and Nunavut. This month, abstracts from about 20 talks and posters relevant to the diamond world are included in the summary. There is some good research happening in the NWT on KIM dispersions by the NWT Geological Survey in collaboration with students and professors. The abstracts are conveniently provided in the Kaiser Research Online Diamond Center and on the conference website.
Elements: In the December issue of Elements, a journal devoted to mineralogy, petrology and geochemistry, there are seven summary papers on topics related to kimberlites and diamond exploration. The papers will be available on the journal's website sometime this month.
This paper is an interesting summary of many aspects of the diamond business and development of Angola from the creation of the first diamond company in 1917 through the end of the Angolan civil war in 2002. With it's diamond and oil resources and a lot of land with a favorable agriculture setting, Angola has so much potential for good economic development.
This paper is a summary of a dissertation on the Sask craton by Czas in 2018 at the U of Alberta. Because of the presence of Archean ages in some crustal material, and significant diamonds in the Fort A La Corne kimberlite field in Saskatchewan, it was postulated that a small Archean craton, the "Sask Craton", surrounded by basement associated with the Paleoproterozoic Trans-Hudson orogeny (THO) was present in the area. Mantle xenoliths were studied and the mantle was found to be lherzolitic with Re-depletion ages having a main mode in the Paleoproterozoic. Currently, Rio Tinto is working in joint venture with Star Diamond Corporation to confirm the economic viability of two kimberlites and assess the economic potential of several others in the Fort A La Corne district. This is an illustration of diamond exploration potential in other Paleoproterozoic terranes throughout the world. Most of these terranes have not been explored to the level of confirmed Archean cratons.
