Writeup from MB 105:

Northwest Africa 10582 (NWA 10582)

Morocco, (Northwest Africa)

Purchased: 2015 Feb

Classification: Ordinary chondrite (H4, melt breccia)

Physical characteristics: Single stone, dark brown crust. The sawn surface shows a black matrix with several metal spots and no evident chondrules.

Petrography: (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi); The thin polished section displays a texture composed of clasts containing rare remnant chondrules within a dark, very fine-grained black matrix. The matrix contains scattered grains of metal and rounded troilite blebs. Shock stages are S2 for clasts and S5 for matrix.

Geochemistry: (V. Moggi Cecchi, G. Pratesi, S. Caporali, M.Zoppi, UniFi) Olivine (Fa 19.3±1.0, N=7), orthopyroxene (Fs 16.7±0.8Wo1.2±0.2, N = 8). Analyses were done for both clasts and matrix.

Classification: Ordinary Chondrite (H5-melt breccia); S5; W3

Specimens: A total of 21.2 g specimen and one thin section is on deposit at MSN-Fi. Tomelleri holds the main mass.
