@FaithfullJohn @jolyon Too bad that it is so altered, but th Cr diopside is still nice.

@Thorium @jolyon there are fresh Scottish mantle xenoliths, but none I've seen have quite such nice chrome diopside. There is a non -mantle Cr-diopside locality too, but that's another story... 😎

@FaithfullJohn @jolyon Love to see/hear more about the fresh mantle xenoliths and chrome diopside if you're ever inclined. As a geologist who has only ever worked in IT, the hostname of my workstation has always been "xenolith".
