Jericho Kimberlite
Kimberlite from Kitikmeot Region, Nunavut, Canada. This hand-sized specimen contains several obvious green chrome diopside and abundant smaller wine-red pyrope garnet, which are colorful kimberlite indicator minerals (KIMs) that a prospector looks for.
The characteristic white fragments are fallback clasts of fine-grained limestone of Paleozoic age. This means the 172 million year old Jericho kimberlite pipe penetrated sedimentary cover rock formation that has since been eroded away.
