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.

The great story about the two Russian women that led the effort to discover the Siberian diamond province is recounted in this Geological Society of London paper. Larisa Popugaeva and Natalia Sarsadskhih discovered the Zarnista kimberlite in 1954, the first kimberlite in Siberia, and were not officially recognized for their work until 1970 and 1990 respectively.
In the battle to fight climate-change, Dr. Greg Dipple at the University of British Columbia has been studying "CO2-hungry" ultamafic tailings from diamond processing plants for use as carbon sinks. I saw him give a great talk on the subject in Vancouver a few years ago. This paper in "Science" summarizes a few carbon-capture studies throughout the world emphasizing the work being done by Dr. Dipple and his students at the Gacho Kue mine in the NWT.
Over the last 5-10 years, the University of Alberta in Edmonton has cranked out a lot of theses and dissertations related to kimberlites and diamonds, focused mainly on Canada, providing timely information to industry and other researchers. Like the other theses and dissertations, this study of the Pikoo kimberlites in northeastern Sakatchewan is available as a free download. The discovery of the Pikoo diamond district, located approximately 280 kilometers northeast of the Fort a La Corne district, in 2013 by North Arrow Minerals represents the last major "diamond rush" in Canada, the first being Lac de Gras in 1991. After the discovery, a major staking rush ensued. This is the first detailed study of the geochronology, petrology and chemistry of the 417 million year old Pikoo kimberlites.
