Writeup from MB 105:

Northwest Africa 10606 (NWA 10606)

(Northwest Africa)

Purchased: 2009

Classification: Ordinary chondrite (H4)

History: 1 stone weighing 86.7 g was found in Morocco in 2009. David Holden acquired the sample from a meteorite prospector in Erfoud, 2009.

Physical characteristics: The stone is dark brown, rounded and is 90% covered by a weathered fusion crust. The interior of the stone is dark brown and shows chondrules, fragments and fresh and weathered flakes of metal and FeS grains.

Petrography: Description and classification (A. Love, App): Sample is transected by numerous FeOH-filled, bifurcating fractures and displays recrystallized chondritic texture. Chondrules are indistinct and have an average diameter of 547 μm. Porphyritic chondrules have crystalline mesostasis.

Geochemistry: (A. Love, App) Olivine Fa 18.4±0.6, N=9; Low Ca pyroxene Fs11.5±4.3Wo 1.2±0.9 (Fs6.5-19.1), N=8.

Classification: Based on textural relationships and equilibrated olivine compositions and unequilibrated pyroxene compositions, this is an H4, S3, W3 ordinary chondrite.

Specimens: An endcut and three slices weighing 17.9 g, and a polished thin section are currently on deposit at App. David Holden holds the Main mass.
