New Geochemical Perspectives 'From Hell to the Himalayas: Thermochronology across Deep Time'
This Geochemical Perspectives issue, by Mark Harrison, describes the origin and application of thermochronology - the use of temperature history information isotopically stored in minerals - to infer geophysical mechanisms acting in the past. It is a personalised account using examples from the author's research ranging across geologic time from the Hadean (4.5-4.0 Ga) to the Pleistocene.
We are very happy to welcome Caroline Peacock (University of Leeds) on the Geochemical Perspectives Editorial Board. Caroline's research explores how mineralogical processes, like mineral sorption, control element cycling and help shape the past, present and future Earth system.
Nominate a scientist for an EAG award: deadlines approaching
Recognizing deserving scientists is at the core of EAG's mission. The EAG Award Nomination Committee is currently working hard to identify potential candidates and nominators, but we need the help of all the community to create a diverse pool of candidates.
Nomination deadlines for: EAG-GS Geochemistry Fellows: 31 October EAG Urey, Science Innovation & Houtermans Awards: 15 November
Earlier today EAG members received an invitation to cast their vote to select three new councillors amongst the five candidates proposed. Our councillors participate in discussions, decisions, and initiatives, and therefore play a crucial role in determining the future of the society. Participation is essential to the success of these elections and we thank our members for taking a few minutes to vote.
EAG Reactions on Critical Mineral Resources - register now!
EAG Reactions is a series of online webinars coupled with engaging round table discussions, designed to foster robust connections between diverse scientific communities.
In this next Reactions on Wednesday 6 November at 16:00 CET, Blandine Gourcel from the French Geological Survey (BRGM) and Tânia Martins from the Manitoba Geological Survey in Canada will share insights from their work in academia and governmental institutions on Critical Mineral Resources. Their presentations will cover research, inventory and exploration of CMR. Following the talks, participants will engage in informal discussions on crucial topics such as securing stable supply chains, the importance of critical minerals in advanced technologies/renewable energy, and the role of geochemistry in critical mineral exploration. Registration is free and open to all!
Organising a short course or conference in Europe in 2025? Apply for EAG Sponsorship by 1 November
The EAG Short Course and Conference Sponsorship Program is open to EAG members organizing a short course or small conference in Europe focused on special topics or techniques from the broad field of geochemistry. The program aims to directly support student attendance at the event.
For events taking place in 2025, the application deadline is 1 November 2024.
Applications for online as well as hybrid and in-person events will be considered.
Recording Available: EAGE-EAG webinar 'Targeting and Predicting key resources of the Energy Transition'
In case you missed the recent webinar you can catch up with Olivier Sissmann and Adriana Traby (IFPEN) who explored the surface detection methods used to locate H2 seeps, and analysed the potential of basin modelling to test scenarios on the generation and migration of Hydrogen, Helium, and Lithium-rich brines.
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 euros to cover registration, abstract fees, and travel expenses where applicable. Applicants may be based in any country.
New Elements issue 'Behind and Beyond Luminescence Imaging'
Luminescence-based optical or SEM images are increasingly used in Earth sciences research. Examples include formation and post-growth history of minerals from their internal textures, taking into account multiple interior regions of complex crystals. For such simple approaches it is actually unnecessary to understand the particular causes of emissions. During the last decade, however, spectroscopic research has led to substantial progress in our understanding of the emissions of minerals...
All EAG members have online access to current and past issues ofElements. 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).
