Abstract
SEVERAL authors1–4 have drawn attention to the possibility that slight variations of composition and structure may be present within the original meteoroid mass which produced the Barringer crater and the Cañon Diablo iron meteorites. Transition between regions rich and poor in cohenite, (FeNi)3C, is not uncommon in large sections of this meteorite, but we now draw attention to a transition of structure from a well developed Widmanstatten to a granular pattern in a 1,235 g individual (Wards Natural Science Establishment No. 34,4,678) which does not contain macroscopically visible inclusions of cohenite.
