Nagjir 001        23º40.6702’N, 14º52.8997’W

Rio de Oro, Western Sahara

Find: 2021

Classification: Carbonaceous chondrite (CV3)

History: 4 pieces that fit together were found within the Nagjir dense collection area near Bir Anzerane, Western Sahara. Carlos Muñecas (Expometeoritos) purchased the samples in July 2021 from a dealer in Morocco.

Physical characteristics: Samples have dark gray-dark brown exteriors and have roughly tabular shapes. The cut face shows the interior has a chondritic texture composed of abundant dark and light-colored chondrules and CAIs set within a dark-colored matrix.

Petrography: Description and classification (A. Love, App) Sample contains chondrules w/ avg. dia of 667 µm (n=39) and CAIs set in 22 vol% opaque matrix. Additional minerals are: chromite, very rare troilite, magnetite and rare phosphates.

Geochemistry: (A. Love, App) Olivine Fa11.0±11.9 (Fa0.3-34.3, Fe/Mn=58.6±30.0, n=24); low-Ca pyroxene Fs1.5±1.8Wo1.0±0.2 (Fs0.5-5.6Wo0.6-1., n=7).

Classification: Carbonaceous chondrite (CV3). Based on textures, mineral compositions, and magnetic susceptibility, sample is a CV3.

Specimens: Carlos Muñecas (Expometeoritos) holds the 1676 g main mass. A polished thin section and a 26.69 g slice and endcut are on deposit at App.
