Writeup from MB 110:

Northwest Africa 14133 (NWA 14133)

Morocco

Find: 2020 Mar

Classification: Ordinary chondrite (H5)

History: (J. Higgins) Mohamed Iken found a single 2057 g stone in March of 2020 in an area between Tagounite and Zagora, Morocco. Mohamed Elguirah purchased the sample and sent to John Higgins for classification.

Physical characteristics: Sample has a dark-brown exterior with visible chondrules on the surface. The cut face shows the interior has a chondritic texture with abundant chondrules separated by oxidized veinlets.

Petrography: Description and classification (A. Love, App) Sample shows a chondritic texture composed of well-defined chondrules and fragments set within a recrystallized matrix crosscut by FeOH minerals. Chondrules have an average apparent diameter of 557 µm (n=119). Chondrules shows recrystallized mesostasis. Most low-Ca pyroxene is orthoenstatite. Secondary plagioclase has an average grainsize of 45µm (n=26). Additional minerals: chromite, secondary calcite, apatite and troilite.

Geochemistry: (A. Love, App) Olivine (Fa17.7±0.2, Fe/Mn=34.5±0.9, n=16); low-Ca pyroxene (Fs15.5±0.2Wo1.3±0.1, Fe/Mn=21.6±0.6, n=14).

Classification: Ordinary chondrite (H5, C-S3, W3). Based on textures, size of secondary plagioclase and mineral compositions, sample is a H5.

Specimens: John Higgins holds the main mass. A polished thin section and a 23.48g sliced individuals are on deposit at App.
