v1n6 From the Editors

As we close the last issue for 2005, we are now into the rhythm of publishing issue after issue. The beat will pick up considerably, however, as we move to publishing six issues a year in 2006. We are pleased with the 2006 lineup and offer you a sneak preview starting on the next page. And we always enjoy hearing from you. Several of our features depend in part on your involvement. Has a colleague been recognized for his or her work?—Consider submitting a short note for People in the News. Have you read an amazing paper?—Drop us a note so we can consider it for the Editors’ Pick. Let us know if there is a topic you would like to read about in a future issue of Elements or even better, consider submitting a proposal.

You will find enclosed with this issue of Elements our first “Mineralogy/Geochemistry Societies Annual Catalogue.” Please keep it, or forward it to a colleague, a student, or your library. If each of you encouraged a colleague or a student to join one of the participating societies, the mineralogy–geochemistry–petrology community would double instantly. Imagine our impact! Membership to any of the participating societies includes a subscription to Elements. The idea of a multi-society catalogue is not new. It was first put forward by Kevin Murphy of the Mineralogical Society several years ago. At that time, even though interest was expressed, the idea did not move forward beyond the discussion stage. Since Elements offers participating societies a way to promote their publications to a wider audience than their own membership, all the societies embraced the idea and “bought” pages of the catalogue. We plan to produce such a catalogue once a year.

While working on this issue, I learned a lot about diamonds and the unique contribution their study has made to our understanding of the mantle. Studying diamonds can be a glamorous occupation at times, as this picture of George Harlow attests. When George sent me the picture for fun, I begged him to allow me to use it.

December 2025 --The Variscan Orogeny in Europe – Understanding Supercontinent Formation

The Variscan orogen formed between 380 and 300 million years ago through several accretionary and collisional cycles, culminating with the construction of the Pangea supercontinent. This process occurred via sequential opening and closure of oceanic basins, synchronous detachment of Gondwana derived continental ribbons, and their outboard amalgamation onto the Laurussia margin. The Variscan orogen is rather unique compared with other orogenic belts on Earth: its overthickened and dominantly magmatic crust in the central belt, surprisingly minor mantle involvement in the magmatic and geodynamic processes, coherent and pulsed magmatism along the collision suture, and its complex accretionary history. Because its final product, Pangea, is the youngest and best-understood supercontinent on Earth, the Variscan orogeny offers clues for understanding the mechanisms of supercontinent formation.
