Writeup from MB 106:
Northwest Africa 5195 (NWA 5195) Morocco Purchased: 2005 Classification: Ordinary chondrite (L6) History: A single stone weighing 690 g was found in Morocco and subsequently purchased in Agadir, Morocco. Thomas Webb acquired the sample from a meteorite prospector in 2005. Physical characteristics: The stone is mottled orangish-brown and has a rounded, triangular shape. The stone is 25% covered by a weathered fusion crust. The cut face of the interior of the stone shows a few chondrules and shiny FeNi and FeS grains. Petrography: Description and classification (Anthony Love, App): Sample displays recrystallized chondritic texture. Droplet chondrules, which survived recrystallization, have an average diameter of 1366 µm (n=6). Porphyritic chondrules are indistinct and have crystalline mesostasis. Geochemistry: (A. Love, App) Olivine Fa24.7±0.2, N=8; low Ca pyroxene Fs2.7±0.2Wo1.2±0.1, N=8; high Ca pyroxene Fs 8.2 Wo44.9, N=1. Classification: Based on mineral compositions, chondrule size and texture, this is an L6, S3, W2 ordinary chondrite. Specimens: An endcut and one slice weighing 21.53 g, and a polished thin section are currently on deposit at App. Thomas Webb holds the main mass. | ||||||||||||||||||||||||||||||||
