Metbase description: Show/Hide
Two stones, weighing 452.6g and 245.4g respectively, were found by Bob Verish in his back yard while he was cleaning out a box of rocks that was part of his rock collection; the specimens may have been collected about 20 years ago in the Mojave Desert; classification and mineralogy; a basaltic shergottite, similar in texture to QUE 94201, J.N.Grossman, Met.
