Writeup

Writeup from MB 88:

Northwest Africa 3004

Morocco

Found 2002

Carbonaceous chondrite (CV3)

A single dull black stone of 175 g partly covered with fusion crust was found by Moroccan nomads and sold in Morocco. Mineralogy and classification (J. Schlüter, Ham): The meteorite consists of chondrules of different structures and mineralogies in the 800 – 2400 μm range with single chondrules up to 5000 μm in size, olivine aggregates, mineral grains and several fine-grained convoluted calcium-aluminium inclusions (up to 2000 μm) set in a dark matrix; rare metal grains. Mean olivine, Fa_4.07 (range Fa_0.33-23.45), mean pyroxene, Fs_1.73 (range Fs_0.59-3.39), Wo_0.72(range Wo_0.48-1.02). Weathering grade: W1, shock stage: S2. Oxygen isotopes (U. Wiechert, ETH): δ¹⁷O= -2.07, δ¹⁸O= +2.49, Δ¹⁷O= 3.39‰; 2^nd analysis δ¹⁷O = -3.29,δ¹⁸O = +0.80, Δ¹⁷O = -3.71. Specimens: type specimen, 22 g Ham, main mass Horst Burkard, Bonn.
