A loose sample of sheared eclogite that Carol Simpson picked up from under a ski lift on the upper slopes of Mucrone, Val d’Aosta, Italy. Rough location: 45° 37’ 24N; 7° 56’ 37E. Part of the Alpine eclogite facies. Carol reports: "Omphacite, jadeite, phengite, quartz in the undeformed rock (retrogressed to amphibole/albite in the shear zone?). Maybe some glaucophane present in this sample, although I don’t think we ever established that for a fact. I was just a PhD student on a field trip to someone else’s field area, and I was only interested in the shear zone :-)" From the structural geology teaching collection of Carol Simpson and Declan De Paor.
