EAG and GS Announce Support for Africa Initiative

AFIPSFor several years, the European Association of Geochemistry and the Geochemical Society have sponsored an outreach program to support geochemistry in under-represented regions of the world. The societies are pleased to announce that in 2018 they will sponsor the recently launched Africa Initiative for Planetary and Space Sciences. Grants from the societies will support two workshops to be developed by the Initiative next year. Learn more about the Initiative

A geochemical link between plume head and tail volcanism
B.J. Peters, J.M.D. Day

Geodynamical models of mantle plumes often invoke initial, high volume plume ‘head’ magmatism, followed by lower volume plume ‘tails’. However, geochemical links between plume heads, represented by flood basalts such as the Deccan Traps, and plume tails, represented by ocean islands such as La Réunion, are ambiguous, challenging this classical view of mantle plume theory. […]

GPL1740_abstract_100FeTiMM – A new oxybarometer for mafic to felsic magmas
R. Arató, A. Audétat

The oxidation state of magmas is a key parameter that is notoriously difficult to reconstruct. The most common approach is via magnetite–ilmenite oxybarometry. However, many natural magmas do not contain ilmenite, preventing application of this technique. […]

GPL1738_abstract100Nickel accelerates pyrite nucleation at ambient temperature
G. Morin, V. Noël, N. Menguy, J. Brest, B. Baptiste, M. Tharaud, G. Ona-Nguema, M. Ikogou, E. Viollier, F. Juillot

Chemical and isotopic compositions of pyrites are used as biogeochemical tracers in Archean to modern sediments. Moreover, pyrite formation from monosulphide precursors has been proposed to be involved in prebiotic chemistry. However, the factors controlling pyrite formation and distribution in the sedimentary record are incompletely understood. […]

GPv6n1_100Future Global Mineral Resources
Nicholas T. Arndt, Lluís Fontboté, Jeffrey W. Hedenquist, Stephen E. Kesler, John F.H. Thompson and Daniel G. Wood

In this issue of Geochemical Perspectives, six authors with wide experience in ore deposit research, exploration and production present an optimistic but realistic appraisal of future mineral resources. They describe how ore deposits form, and how they are found, assessed, mined and processed. They discuss the critical differences between mineral reserves and resources, how economic and societal factors influence supply, and the critical roles that geoscientists will continue to play. The authors argue that mineral resources will remain adequate well into the future.
