Writeup from MB 109:
Northwest Africa 4295 (NWA 4295) Morocco Purchased: 2006 Mar Classification: Enstatite chondrite (EL melt rock) History: Purchased by Adam Hupe in March 2006 from a dealer in Erfoud, Morocco. A small specimen was sold to PSF in 2007. Physical characteristics: Five similar stones (total weight 312 g) consisting of aggregates of small whitish grains crosscut by distinctive thin compression fractures filled with terrestrial limonite. Petrography: (A. Irving, UWS & J. Boesenberg, BrownU) All five stones were examined petrographically. They are fine grained aggregates of predominantly enstatite (mostly as prismatic grains) with accessory sodic plagioclase, iron hydroxides (after primary metal), troilite, daubreelite and schreibersite. No fresh metal was found in the studied thin sections. Rare but clearly defined, spherical RP chondrules are present, and there are subparallel veinlets of secondary iron hydroxides and some calcite. Geochemistry: Enstatite (Fs0.5±0.2Wo1.4±0.0 (range Fs0.3-0.8Wo1.4, N = 6), plagioclase (Ab80.5-81.8An15.6-14.2Or4.0-3.4, N = 5). Classification: EL3-melt rock. Paired with Al Haggounia 001 and related material. Specimens: 20.5 g including one polished thin section at UWB; 9.04 g at PSF; remainder with AHupé. | ||||||||||||||||||||||||||||
