ABSTRACTThis paper contains an account of a 29.547‐g. coppery nugget reported to have been observed to fall in May, 1931, at Eaton, Weld Co., Colorado (coördinate number = 1047,405), that the writer is able to explain only on the hypothesis that the specimen is a meteorite of an entirely new type (copper‐zinc‐lead), coördinate with the sideritic variety (or nickel

摘要:

ABSTRACT AND INTRODUCTIONThe present communication, in so far as it relates to a note on contraterrene meteorites,1is simply an elaboration of certain remarks which I made extemporaneously at the time the then Secretary, Dr. Robert W. Webb, read Dr. C. C. Wylie's paper at the Eighth Meeting of the Society for Research on Meteorites held in Flagstaff, Arizona, in June, 1941. In so far as this communication relates to three more recent notes on the mass of the meteorite responsible for the Canyon Diablo, Arizona, Meteorite Crater,2it is intended to justify objections to Wylie's results already expressed in private letters to him.

摘要:

ABSTRACTThe meteoritic falls of the world have been studied in an attempt to learn whether they support the hypothesis that a governing cause of multiple falls is the fact that stones are more friable than irons and are thus more likely to disintegrate under the effects of external forces. A statistical test has been applied to the data and has been found strongly to support this hypothesis.
