Rocks from Space Picture of the Day June 15, 2008
A 265 gram individual of the Kainsaz carbonaceous chondrite (CO3.2) that fell September 13, 1937 at 14:15hrs near Muslyumovo, Tartarstan, in Russia. The specimen is a fully crusted individual with pyramidal shape and trapezoid base. The specimen has seven surfaces of which two display primary fusion crust while the remaining show secondary crust. The mass apparently sheared off a larger mass while still in the ablative flight phase. This particular meteorite was recovered by a Russian field team in Spring 2008 by metal detector. Although in the ground for 71 years the meteorite shows only very little weathering.
