Northwest Africa 16327 (NWA 16327)

(Northwest Africa)

Purchased: 2021 Sept

Classification: Ordinary chondrite (L4)

History: A single stone was purchased via post from Australia by Naren King owner of Crystal Castle in September 2021 from Moroccan meteorite dealer Mohamed Elguirah, who purchased it at an earlier time in northwest Africa from an unknown source.

Physical characteristics: A single red brown stone of approximately 31 kg with metal and chondrules visible through a mostly wind polished exterior. Some sandblasted fusion crust remains. The stone has a somewhat pyramidal shape.

Petrography: (D. Dickens, CCMS) Optical and microprobe examination of polished probe mount and BSE images show an unbrecciated chondritic texture with sparse equilibrated chondrules lacking sharp delineation set in a coarse-grained recrystallized matrix containing stained metal, and accessory oxides and sulfides. No Plagioclase was observed in the matrix.

Geochemistry: (D. Dickens, CCMS) Olivine Fa24.8±0.3, range Fa24.6-25.0, n=2; low-Ca pyroxene Fs21.7±1.6Wo1.4±0.2, range Fs20.4-25.7Wo1.1-1.7, n=10.

Classification: Ordinary chondrite (L4)

Specimens: Type specimen location Cascadia; Main mass with Naren King
