Writeup

Writeup from MB 104:

Mauritius, reclassification

Petrography: (J. Gattacceca, CEREGE): Petrographic observation of a polished thin section obtained from the main mass (provided by Peter Davidson, NMS) shows a chondrite breccia with mm-sized, angular, dark, shocked chondritic clasts set in a light-gray chondritic host lithology. Average plagioclase grain size is <50 μm in the light host lithology, and >50 μm in the dark clasts. Metallic copper to 10 μm is found in the host lithology.

Geochemistry: EMP analyses of the same thin section give Fa_29.4±0.1(n=10) Fs_25.2±0.5Wo_1.9±0.5(n=8). Plagioclase, An_10.5Ab_87.5Or_2.0(n=3). Dark clasts Fa_29.6±0.3(n=9) Fs_26.0±0.4Wo_2.1±0.3(n=7). Magnetic susceptibility (log χ, χ in 10^-9 m³/kg): 4.15 (NMS), 4.11 (NHMV), 4.20 (MGMH).

Classification: LL5, with LL6 clasts.
