21.05.2014|Fredericton: The Mineralogical Association of Canada awards Felix V. Kaminsky (Vancouver), Richard Wirth and Anja Schreiber (both GFZ, Potsdam) the prestigious Hawley Medal for the best paper published in The Canadian Mineralogist in 2013.

The citation reads:”Recent studies of mineral inclusions in diamond have provided us with unprecedented information about the mineralogy of the lower mantle, and the nature and role of fluids in the deep Earth. The study of Kaminsky, Wirth and Schreiber (2013) represents a significant advance in this field. The authors carefully used transmission electron microscopy, electron diffraction, analytical electron microscopy and other methods to document the associations, textures and compositions of micro- and nano-mineral inclusions in lower mantle diamond. Their results demonstrate that the diamond formed in a lower mantle, carbonatitic, carbonate-halide-phosphate-fluoride medium, which was enriched in rare earth elements and volatiles. Future studies will almost certainly focus further on the origin of this primary, deep-seated carbonatitic magma, and its significance in models for the accretion and differentiation of the Earth.“

The Medal is presented at GAC-MAC (Geological and Minealogical Associations of Canada) Conference in Fredericton, New Brunswick, Canada on Wednesday, May 21, 2014.
