Dear all, Please consider submitting an abstract for the session "*The Testimony of Minerals: A Celebration of Edward S. Grew at 80" * at the 4th European Mineralogical Conference, 18-23 August, in Dublin and help us celebrate Ed's incredible contributions to the geosciences on the occasion of his 80th birthday! We already got some great submissions, but there is room for more! *New abstract deadline is April 19th.* *Session description:* Throughout his remarkable career, Ed Grew has deciphered and shared the deep-time stories locked in rocks and minerals. In works of meticulous scholarship and deep insight, Ed has revealed the rich context and varied processes of mineral formation in deposits from Greenland to the Antarctic, from metamorphics of Tajikistan to his beloved Maine pegmatites. He is the world’s authority on the minerals of lithium, beryllium, and boron, including pioneering studies on their mineral evolution and ecology. His work on metamorphic minerals, notably the garnet group and sapphirine-surinamite groups, are classic contributions. In short, Ed Grew’s influence on the mineralogical community has been lasting and profound. This session in honor of Ed Grew’s long and distinguished career welcomes a wide range of contributions that touch on the varied aspects of his research, including (but not limited to) complex pegmatites, the geology and mineralogy of Antarctica, metamorphic minerals, the minerals of rare elements, mineral evolution and ecology, and varied aspects of petrologic mineralogy. *Keynote speakers and talk title: * Bob Hazen – Data-driven discovery in mineralogy: Mineral evolution, mineral ecology, and Edward Grew's legacy Horst Marschall – Mechanisms of uranium incorporation into garnet There will also be a* special issue of Mineralogical Magazine in honour of Ed, *organized by guest editors Gerhard Franz, Bob Martin, and Jesse Walters.
