Description: 48.45 gram specimen of an amazing "harzburgitic" plutonic peridotite diogenite with large light green olivine crystals visible on most of the interior and exterior. Some glassy black remnant fusion crust remains from the intense plasma created during its transit through the Earth's atmosphere. This is a very rare type of plutonic olivine-rich diogenite known as a peridotite. This extraterrestrial stone displays striking petrological similarities to the terrestrial ultramafic igneous peridotite called harzburgite found in the Harz Mountains of Germany. As a peridotite with nearly 75% olivine, this diogenite is not quite a "dunite", but with only a few notable exceptions, is one of the most olivine-rich diogenites ever discovered. A truly exceptional and rare meteorite.
The HED Meteorites: The HED meteorite group is so named for the three types of meteorites that comprise the group; Howardite, Eucrite and Diogenite. The Eucrite and Diogenite have distinct mineralogies, the Howardite is a breccia of the Eucrite and Diogenite.
The HEDs are differentiated achondritic meteorites thought to originate from Vesta, or smaller Vesta-like asteroids known as vestoids that were likely once part of a larger Vesta. The olivine-bearing diogenites are thought to form in the upper mantle or lower crust of Vesta, with, plutons, dikes and/or batholiths of diogenitic material pushing into the eucritic crust.

| Writeup | Writeup from MB 114: Ksar Ghilane 024 (KG 024) 32.999° N, 9.633° E Quibili, Tunisia Purchased: 2025 Classification: HED achondrite (Diogenite, olivine) History: Purchased in 2025 by Ahmed Saleck from a meteorite hunter in Tunisia. Physical characteristics: Three dark colored stones, 67, 453, and 545 g, all with light green crystals visible on most of the exterior. Remnant glassy fusion crust is present in some areas on all three stones. Caliche partially covers one side of the two larger stones. Saw cut reveals a course-grained crystalline interior. Petrography: (D. Dickens, LMAC) This meteorite is a coarse-grained, igneous, harzburgitic peridotite with a cumulate texture. Mineral mode is olivine ~73.5 vol.%, low-Ca pyroxene ~25.2 vol.%, with oxides, sulfides and metal making up the remaining ~1.3 vol.%. Spheroidal and subhedral olivine grains are often tightly packed and enclosing pyroxene, occasionally transitioning to areas where olivine is less dominant and poikilitically enclosed by pyroxene. Symplectic intergrowths of chromite and silica polymorph often decorate outer rims of olivine grains. Accessory phases are aluminous chromite, troilite, and low-Ni kamacite. Geochemistry: (D. Dickens, LMAC and A. S. Bell, UColo) Olivine Fa27.8±0.3 ,FeO/MnO = 46.1±2 (n=31). Low-Ca pyroxene Fs22.7±0.3Wo2.9±0.6, FeO/MnO = 29±1 (n=21). Classification: Diogenite-olivine (harzburgitic) Specimens: Type specimen of 20 g at TCU. 545g with Monnig Meteorite Collection, and remainder with Ahmed Saleck and Omar Bourki. |
