Northwest Africa 11979 (NWA 11979)

(Northwest Africa)

Purchased: Nov 2015

Classification: Ordinary chondrite (H~6)

History: Purchased by Li Bofang from a Morrocoan dealer at the mineral show in Beijing in Nov. 2015. Later the main mass was donated to Qu Pan.

Physical characteristics: A 78.1 g dark brown elongated stone. Cut face shows fine distributed tiny metal specks all over the surface.

Petrography: (R. Bartoschewitz, Bart, B. Li, Beijing) cut surface shows light/dark phases with shock veins, strong recrystallized matrix and poor defined chondrules (0.2-0.5mm, av. 0.3 mm). The dark phase is finer grained than the lighter one.

Geochemistry: (R. Bartoschewitz, Bart) Magnetic susceptibility log χ (× 10^-9 m³/kg) = 5.11.

Classification: ordinary chondrite (H~6)

Specimens: 16.8 g on deposit at Kiel, B. Li holds the main mass and 11.2 g with Bart.
