Writeup from MB 104:
Northwest Africa 10017 (NWA 10017) (Northwest Africa) Purchased: 2012 Classification: Ordinary chondrite (H5) History: One stone weighing 45.4 g was found in Morocco in 2012. David Holden acquired the sample from a meteorite prospector in Erfoud, 2012. Physical characteristics: The stone is dark brown and has an angular shape displaying many small, shallow regmaglypts. The stone is completely covered in a weathered fusion crust. The cut face of the interior of the stone is dark brown, porous and displays small, closely packed chondrules and fresh and weathered flakes of metal. Petrography: (A. Love, App): Sample displays recrystallized chondritic texture. Many chondrules are defined yet have turbid to recrystallized mesostasis and have an average diameter of 569 μm. Taken in concert with irregular fractures, sharp optical extinction and monocrystalline troilite, PCAs and metallic Cu suggest sample has been annealed subsequent an impact event with a maximum prior shock level of S3. Geochemistry: (A. Love, App) Olivine Fa19.7±0.2, N=14; low Ca pyroxene Fs17.5±0.3Wo2.7±1.1, N=12 Classification: Ordinary chondrite (H5, S3, W3) Specimens: Two slices weighing 9.1 g, and a polished thin section are currently on deposit at App. | ||||||||||||||||||||||||||||||||
