Writeup from MB 106:

Ramlat Fasad 028        18°40.478’N, 53°09.797’E

Zufar, Oman

Find: 05.02.15

Classification: Ordinary chondrite (L3)

History: A single stone was found during a search for meteorites.

Physical characteristics: Dark-brown single stone, wind-ablated with protruding chondrules, partly preserved fusion crust.

Petrography: (B. Hofmann, NMBE, Å. Rosén, Bern and E. Gnos, MHNGE) Typical chondritic texture with very well defined chondrules. Mean apparent chondrule size 0.78±0.40 mm (N = 103).

Geochemistry: (Å. Rosén, Bern) Olivine compositions are Fa23.6±7.2, range Fa7.0-41.1 (N = 64). Fa by XRD is 27.5. Orthopyroxene compositions are Fs14.9±8.1Wo1.4±1.3, range Fs2.6-29.1Wo2-4.5 (N = 37). Cathodoluminescence (E. Gnos, MHNGE) shows dominant blue colors, with some chondrules showing red and yellow luminescence. Olivines in red-yellow luminescent chondrules have Fa0.5-5.1 (N = 68).

Classification: Based on mineral compositions and chondrule size this is an L chondrite. The petrologic type is ~3.5-3.7 based on silicate heterogeneity but the sample contains some lower petrographic grade material. Shock grade S1, weathering W3.

Specimens: All at NMBE
