New Geochemical Perspectives: ‘Metallogeny and Mineral Exploration – Some Personal Reminiscences’
Successful exploration for mineral resources, including those critical for the energy transition, is underpinned by continuing advances in geological and metallogenic understanding. This issue, written by Richard H. Sillitoe, provides a personalised global perspective on some of these advances during the past half century, with a particular focus on copper and gold deposits
Geochemical Perspectives is an open access community journal published by the European Association of Geochemistry. EAG members who opted to receive a print copy will receive it soon.

2023 Distinguished Lecturer Sandra Arndt reports back from her tour of Eastern Europe
Sandra Arndt gave a series of lectures in Eastern Europe at the end of 2023 explaining how biogeochemical models can be used to study crucial carbon cycle-climate feedbacks. Recording of two lectures is available.
The firstEAG Reactions webinar,'Academics working on carbon dioxide removal CDR projects', with guest speakers Rebecca Tyne and Noah Planavsky, took place on 8 March. In case you missed it or want to watch again, the recording is now available!
EAG Student Sponsorship Program: Next deadline 1 May
The EAG Student Sponsorship Program supports onsite participation at events held in Europe, or online participation at events held anywhere in the world. Successful applicants will receive sponsorship of up to €1000 to cover registration, abstract fees, and travel expenses where applicable. Applicants may be based in any country.

Latest Elements: 'Metamorphic Duality in SW Japan—The Sanbagawa-Ryoke Classic Example of Paired Metamorphism'
Subduction, where one plate dives beneath another, controls long-term whole-Earth cycling of rocks, fluids, and energy. Plates subduct faster than they heat up, making them the coldest parts of the Earth’s interior. Fluids released from these cold plates rise into hotter overlying rocks, forming magma that feeds surface volcanism. Cold deep conditions associated with subduction complemented by hot shallow conditions under volcanic arcs are reflected in the presence of pairs of metamorphic belts, representing sites of ancient subduction. This issue of Elements guides readers through a premier example of paired metamorphism: the Cretaceous SanbagawaRyoke metamorphic pair of Japan...
All EAG members have online access to current and past issues of Elements. Members who have selected to receive print copies of Elements, will shortly receive the latest issue by post (log into the EAG Membership Platform to verify your preferences and postal address).
Goldschmidt Conferences
The Goldschmidt 2024 plenaries have been announced: Catherine Chauvel from the Institut de Physique du Globe de Paris, France, Jiubin Chen from Tianjin University, China, Corinne Le Quéré from the University of East Anglia, U.K., Christopher Reddy from the Woods Hole Oceanographic Institution, U.S., and Ellen Stofan from the Smithsonian Institution, U.S., will all be presenting on various topics this year.
Comparative 142Nd and 182W study of MORBs and the 4.5 Gyr evolution of the upper mantle
New high precision Nd and W isotopic compositions were obtained on the same basalt samples from the Pacific Antarctic Ridge. These provide the best estimate so far for the μ142Nd and μ182W values of the...
The isotopic signature of UV during bacterial reduction
The two step electron transfer during bacterial reduction of UVI to UIV is typically accompanied by mass-independent fractionation of the 238U and 235U isotopes, whereby the heavy isotope accumulates...
Strongest ocean current on Earth is speeding up and causing problems
[Earth.com] The Antarctic Circumpolar Current (ACC) is the most powerful current on Earth, encircling Antarctica and influencing the global climate. Over the last few decades, observations show that it has been speeding up. Experts were...
Cosmic cleaners: the scientists scouring English cathedral roofs for space dust
[The Guardian] Mini missions are being launched amid the spires – a haven for dust particles that may contain clues about the cosmos and the early Earth. On the roof of Canterbury Cathedral, two planetary scientists are searching for cosmic...
Missing Link Uncovered – A New Origin Story of How the Continents Developed
[SciTechDaily] Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed—a revised origin story that doesn’t require the start of plate tectonics or any external factor to explain their formation. Instead, the findings...
Life’s vital chemistry may have begun in hot, cracked rock
[New Scientist] Chemical reactions key to the origin of life on Earth could have occurred as molecules moved along thermal gradients within networks of thin rock fractures deep underground. Such networks, which would have been...
NASA’s New Asteroid Sample Is Already Rewriting Solar System History
[Scientific American] Scientists have scarcely begun studying pristine material from asteroid Bennu brought back to Earth by the OSIRIS-REx mission, but have already found several surprises. Meteorites are messengers from the depths of...
Searching for the decay of nature's rarest isotope: Tantalum-180m
[Phys.org] Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope. In excited states, a nuclei's protons or...
