Writeup from MB 103:

Al Jawf 001 (AJ 001)        29°44.57’N, 39°47.329’E

Al Jawf, Saudi Arabia

Found: 2009 May 7

Classification: Ordinary chondrite (H4-5)

History: Mr. Jahn found the meteorite while he was working in Saudi Arabia. He brought the sample to the University of Tennessee in May 2013, where it was analyzed and identified as a meteorite.

Physical characteristics: The stone is covered with black fusion crust and indentations.

Petrography: The cut surface shows a coarse brecciated texture, with clasts ranging up to 4 cm. Abundant metal grains are visible. Clasts vary from relatively unshocked (S1) to impact melted.

Geochemistry: The Fa and Fs values represent mean values of all the clasts. There is no significant difference in the Fa and Fs values for the type 4 and type 5 clasts.

Classification: A number of individual clasts were analyzed and their olivine and pyroxene compositions and textures indicate classification as H4 or H5. The clasts are distinguished based on texture and on percent mean deviation of the low-Ca pyroxene.

Specimens: 20 g UTenn, 327 g SI.
