For geochronologists it is all about precision and accuracy. For petrochronologists it is more about precise positioning of those ages to trace back the evolution of a rock. For many, it is not just about getting a crystallisation or metamorphic age, it is about knowing when and at what conditions a given rock experienced certain petrogenetic processes. As we progressed from geochronology to petro ...[Read More]

Listvenite (sometimes spelt listwanite or listwaenite) is the product of a chemical reaction between peridotite and carbon dioxide, and it is truly strange! I first came across listvenites working on the Semail Ophiolite, Oman, during my PhD. The Semail Ophiolite i ...[Read More]
