Writeup from MB 110:
Northwest Africa 14353 (NWA 14353) Morocco Find: 2021 Classification: Carbonaceous chondrite (CVred3) History: A single sample was purchased by Carlos Muñecas (Expometeoritos) in Mauritania in July 2021. Physical characteristics: Sample has dark gray-dark brown exterior and irregular shape. The cut face shows the interior has a chondritic texture composed of abundant dark and light-colored, ellipsoidal chondrules and CAIs (that define a preferred orientation) set within a dark colored matrix with metal and sulfides. Petrography: Description and classification (A. Love, App) Sample shows chondritic texture showing an alignment of ellipsoidal chondrules with an avg. dia. 651 µm, n=53) and CAIs set in 28 vol% opaque matrix. Additional minerals are: chromite, kamacite and taenite, troilite, magnetite and rare phosphates. Geochemistry: (A. Love, App) Olivine Fa8.0±17.1 (Fa0.4-64.6), Fe/Mn=26.6±24.4, n=18); low-Ca pyroxene Fs2.4±2.5Wo1.0±0.2 (Fs0.7-8.0Wo0.8-1.4, n=10); pigeonite Fs5.8-16.8Wo8.9-6.3, n=2; high-Ca pyroxene Fs0.9Wo36.5, n=1; sulfides contain 0.1 wt% Ni, n=6. Classification: Carbonaceous chondrite (CVred3). Based on textures, mineral compositions, magnetic susceptibility and lack of Ni in sulfides, sample is a reduced CV3. Specimens: Carlos Muñecas (Expometeoritos) holds the main mass. A polished thin section, and 29.63 g are on deposit at App. | ||||||||||||||||||||||||||||||||
