Writeup from MB 111:

Northwest Africa 14793 (NWA 14793)

Morocco

Purchased: 2021

Classification: Carbonaceous chondrite (CV3)

History: Many samples ranging in weight from 10 to 672 g were purchased from Yunes Chaoui and Yahdih Buhali Omar by Adrián Contreras Gómez (CRATER meteorites) and Viktor Ivanov (VIP meteorites) in Roquetas de Mar, Spain in July 2021.

Physical characteristics: Samples are dark-black colored and irregular shaped. Chondrules are visible on the outer surface.

Petrography: Description and classification (A. Love, App) Sample is composed of dispersed chondrules and CAI’s in a fine-grained opaque matrix (~50 vol%). Chondrules have an average apparent diameter of 937 µm (n=17). Additional minerals: chromite, magnetite, weathered sulfides and rare unweathered FeNi metal.

Geochemistry: (A. Love, App) Olivine (Fa10.5±12.8, Fe/Mn=76.3±49.2, n=2); low Ca pyroxene (Fs0.9-1.3Wo4.6-1.3, n=3); pigeonite (Fs1.2Wo12.5, n=1); high Ca pyroxene (Fs0.8-1.4Wo34.4-33.3, n=2).

Classification: Carbonaceous chondrite (CV3). Based on matrix and CAI abundance and chondrule diameter, sample is a CV3.

Specimens: The 672 g main mass is jointly owned by Adrián Contreras Gómez (CRATER meteorites) and Viktor Ivanov (VIP meteorites). A polished thin section and several fragments and slices weighing 21.28 g are on deposit at App.
