Dear All, Apology for bulk posting. We are organizing the following session in the 25th Goldschmidt Conference 2015 at Prague (August 16-21) under the *Theme 12 (Mineral resources in an evolving Earth)*. Please consider to submit your abstract and feel free to attend the session. Abstract submission is open now and you can submit your abstract using following link of the Goldschmidt 2015 conference website: http://goldschmidt.info/2015/abstracts *Title of the Session 12b (under SGA & IAGOD-CODMUR):** Processes and Deposits of Ultramafic-Mafic Magmas Through Space and Time <http://goldschmidt.info/2015/program/programViewThemes#session12b>* *Details of the Session 12b:* Production and use of magmatic ores such as Ni-Cu sulfides, platinum-group elements (PGEs), chromite and Ti-V-bearing magnetite is one of the most dynamic and effective branches of world economy. Magmatic ore deposits are formed from ultramafic-mafic magmas due to high temperature crystallization processes and directly linked to the evolution of the parental magmas through space and time. The ore forming processes under magmatic system have two end members: (i) concentration of ore minerals as a direct consequence of magmatic crystallization dominated by silicate melt-crystal equilibria and (ii) (magmatic) hydrothermal processes where concentration of ore minerals are from magmatic hydrothermal fluids by crystallization dominated by crystal-volatile equilibria. This particular session will seek to understand the fundamental processes which control the formation of the deposits of the ultramafic-mafic magmas covering chromite, PGE, Ni-sulfides, Ti-V-bearing magnetite through space and time. In addition, this session will contribute in understanding the recent development in the fields of magmatic ore deposits as a whole. *Keynote &* * Invited talk: Shoji Arai (Kanazawa University, Japan), James Brenan (University of Toronto, Canada), Suzanne Y.
