A sample of an ordinary chondrite fall, Allegan, was shown by 57 Fe Mössbauer spectroscopy to be unweathered. Using aerated deionized water at 25° and 0 °C, and in one case with dissolved salts added, an attempt was made to simulate meteorite weathering processes in the hot and cold desert environments where these samples accumulate. The progress of artificial oxidation was monitored by 57 ...The significantly weathered meteorite measured 20.5 inches long by 20 inches wide by 13 inches thick. The finder, Mr. John W.
