Writeup from MB 104:

Northwest Africa 10037 (NWA 10037)

Morocco

Purchased: 2014

Classification: Enstatite chondrite (EL6)

History: Purchased by Nicola Castellano at the Genova Mineral Fair in May 2014 from a Moroccan dealer.

Physical characteristics: A single piece weighing 43 g partially covered by fusion crust.

Petrography: (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi); The thin section texture consists of a pyroxene-dominant matrix, with minor plagioclase, and very rare relic chondrules (mainly RP type, with minor GP) ranging in size from 0.5 to 1.1 mm. No iron oxides/hydroxides veinlets can be observed. Kamacite and troilite are the main opaque phases, partially weathered to iron oxides. Accessory phases are alabandite and daubreelite as blades in troilite. The presence of alabandite, An content of plagioclase and Si content of kamacite point to a classification as EL chondrite.

Geochemistry: Orthopyroxene (Fs0.4En98.2Wo1.4), plagioclase (An15.4Or5.4); Si in kamacite = 0.6 wt.%, Ti in troilite = 6.3 wt.%

Classification: Enstatite chondrite (EL6)

Specimens: A total of 8.6 g specimen and one thin section is on deposit at MSN-FI. Castellano holds the main mass.
