The Tamdakht meteorite fell near Ouarzazate, Morocco on 20 December 2008 producing a strewn field of approximately 25 kilometres (16 mi) by 2 kilometres (1.2 mi) and two small impact craters, one of about 1.1 metres (3 ft 7 in) diameter and 70 centimetres (28 in) depth at 31°09.8′N 7°00.9′W / 31.1633°N 7.0150°W and the other of about 20 centimetres (7.9 in) diameter and 10 centimetres (3.9 in) depth at 31°09.9′N 07°02.3′W / 31.1650°N 7.0383°W.[1]
The meteorite is named after a village close to the fall.[2]

Mineralogy
[edit]Petrology: (by Albert Jambon, Omar Boudouma, D. Badia UPVI and M. Denise, MNHNP[1]): Abundant chondrules with visible but not well-delimited outlines. Chondrule size is 0.1 to 1.5 mm. Dominant olivine and orthopyroxene. Abundant chromite, rare clinopyroxene and ilmenite. Numerous pockets with chromite, plagioclase and phosphate (merrilite and Cl-apatite). Kamacite, with deformed Neumann bands, and taenite, twinned troilite. Copper. Mode: metal+troilite 10%.
