an online archive of the Sheahan Diamond Literature Compilation organized by year and by author that includes article links and abstracts for the current year

Register early for the 11th International Kimberlite Conference (11 IKC) to secure your place on the world-class field trips (information is available at www.11ikc.com) Registration opens 16:00 GMT 12 September 2016 including:

• conference registration (first come, first served)

• field trip registration (first come, first served) • short abstract submission • financial support requests • accompanying persons registration • onsite hotel bookings

****I missed a set of references from 2010 ** I think the material is still relevant in most of the papers. I kept the use of AK6 ( Karowe) as used in their titles. The Southern African Institute of Mining and Metallurgy 4th Colloquium on Diamonds – Source to use, 24 papers published in 2010. The set of individual papers are available on the internet ( except for one vanStaden) I have listed them with regular new technical references herewith.
