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 are meteorites with distinct chemistries, while the Howardite is a mix of the Eucrite and Diogenite material. The HEDs are differentiated achondritic meteorites, thought to originate from the large differentiated asteroid 4 Vesta. The Vesta parent body origin for the HED clan is considered to have been conclusively established for many years. However, some leading researchers are now starting to suspect they originated from a larger Vesta-like asteroid that was blown apart long ago. This is because we also find a class of iron meteorites with the exact isotopic genetics as the HED clan, leading some researchers to conclude the HED meteorites come from a larger Vestan-like body that was in a cataclysmic collision that liberated part or all of its metal core. This hypothesis does not rule out the possibility that all of the material including Vesta and the Vestoids and the HED meteorites were once part of a much larger dwarf planet prior to this collision.

Northwest Africa 10962 (NWA 10962)

(Northwest Africa)

Find: 2015

Classification: HED achondrite (Eucrite, unbrecciated)

History: Purchased by Fayssal Mezgouri in 2015 from a nomad in northwest Africa and sold to Dustin Dickens in 2016.

Physical characteristics: Two stones of approximately equal mass with glassy, partially oxidized fusion crust on one side of each and sand-ablated patina on the remaining surfaces.

Petrography: (Z. Guo, UWO) Medium grained igneous rock. Modal abundances and corresponding grain sizes: plagioclase 60% (400-500 m), pyroxene 40% (300-1000 m) and metal ~1% (100-200 m). Magnetic susceptibility log ( 10 -9 m 3/kg) = 3.81. Undulatory extinction is present in some plagioclase. Metal has a narrow oxide rim.

Geochemistry: Mineral composition and geochemistry: Pyroxenes: low-Ca Fs 58.6 1.4Wo 3.6 1.8 (N=6), High-Ca: Fs 29.3 2.1Wo 39.9 2.4 (N=9), Fe/Mn ratio of 27.3 0.8 (N=15). Plagioclase: An 89.7 0.3 (N=10).

Classification: Eucrite, unbrecciated.

Specimens: 21.9 g at UWO including a thin section.
