Scientific paper

It is noted that until recently, no terrestrial analogues of meteoritic and lunar chondrules were known. The impact breccia suevite of the Noerdlinger Ries Crater, Germany, contains both chondrules and glass spherules, in addition to accretionary lapilli, all of which are found imbedded within the fine-grained matrix of the suevite. The chondrules exhibit many of the textural features characteristic of meteoritic and lunar chondrules. Lithic chondrules and fluid drop chondrules are present, the latter's composition being quite similar to that of glass bombs and glass fragments in the suevite. It is noted that fluid drop chondrules developed from glass spherules through slow devitrification in the hot suevite ejecta masses after deposition. On the whole, fluid drop chondrules, lithic chondrules and glass spherules are found to be rare in the suevite, with fluid drop chondrules prevailing. The detection of chondrules from a terrestrial impact crater corroborates theories of an impact origin for meteorite and lunar chondrules. Accretionary lapilli also represent material formed through impact.
