NWA 8134, H4 Chondrite, Uncut Fragment, 5.6g

$25.00

NWA 8134 was first recovered out of the Saharan Desert of Morocco in 2013. The find consisted of a single small stone. A sample was analyzed and it was classified as a H4 chondrite that is mildly shocked at S2 and lightly weathered at W2. It consists of a darkened matrix filled with tiny glassy chondrules. The specimen being offered here is an uncut fragment that has some wind-polished desert varnish and remnant crust. It weighs approx. 5.6 grams. This is an attractive little thumbnail piece.

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing the specimen shown. Your purchase will include a labeled gemjar for safe storage.

Northwest Africa 8134 (NWA 8134)

(Northwest Africa)

Purchased: 2013 Oct

Classification: Ordinary chondrite (H4)

History: Purchased by Adam Aaronson in Temara, Morocco in October 2013.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, relatively small chondrules (apparent diameter predominantly 350±250 μm, but some chondrules are in the 1.5-2.2 mm range) in a dark reddish-brown matrix containing altered metal. Glass is present in some chondrules. Minerals are olivine, orthopyroxene, augite, sodic plagioclase, altered kamacite, chromite and troilite.

Geochemistry: Olivine (Fa16.9-17.3, N = 3), orthopyroxene (Fs14.5-14.6Wo0.4-2.7, cores Fs4.6.Wo0.4; N = 3), augite (Fs6.3-13.5Wo38.8-43.3, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg)=4.88.

Classification: Ordinary chondrite (H4).
