Ancient Murowa Kimberlite Pipe - Zimbabwe

Murowa Kimberlite Pipe — 34g — Zimbabwe

This diamond-polished flat Murowa kimberlite disc offers a rare window into a 520-million-year-old explosive volcanic event that formed the Murowa K1–K3 pipes during the Pan-African Orogeny. Unlike the classic Kimberley pipes of South Africa, the Murowa body is older, more volcaniclastic, and preserves rounded olivine macrocrysts suspended in a fine tuffisitic matrix — a signature texture of crater and diatreme-facies kimberlite.

Geological Significance of Murowa Kimberlite

Murowa kimberlite is part of a ~520 Ma magmatic event, making it hundreds of millions of years older than Kimberley-type kimberlites. Its dark, fine-grained groundmass and abundant, rounded olivine megacrysts reflect explosive emplacement, pipe-wall collapse, and rapid transport of deep-mantle material to the surface. This specimen captures that history in a single, striking disc.
