Hello List,
Below is part of the description on the Monahans (1998) found at:
http://www.uark.edu/studorg/metsoc/metbull/bull82.htm#monahans
Two stones, weighing 1344 g and 1243 g, fell in the city of Monahans, Texas,
after two sonic booms and a fireball were observed over a wide area (up to 100
km from the fall site). One stone penetrated the asphalt on a city street and
was found in the sandy subsurface. Classification and mineralogy (M. Zolensky
and G. Lofgren, JSC): a light-dark breccia, with light and black clasts in a
gray-colored, pulverized host matrix; olivine, Fa18.8 (host); pyroxene,
Fs17.1Wo1.4 (host); plagioclase, An1–19Ab70–75Or6–29 (all lithologies);shock
stage S2 (light clasts) to S4 (black clasts); the gray-colored matrix material
contains blue crystals of indigenous halite and sylvite, some up to 3 mm in
diameter, some euhedral.
How many other meteorites contain "blue crystals of indigenous halite and
sylvite...some euhedral." And is this unusual and/or rare?
