He said he picked it from the field to closer examine it, and had to drop it immediately because of its high temperature. He did not notice any sound or light phenomena, which should have accompanied a presumed fall. Mr. Allini brought the stone home claiming it was a meteorite; but after a teacher of the local school told him it was a slag, he disregarded it. In 1972 a curious relative of Mr. Allini, the young Carla Allini, showed it to her teacher Enrico Affini, who submitted it to the experience of Giuseppe Giuseppetti, professor of mineralogy at the University of Pavia. Based on visual examination and on preliminary bulk analyses carried out in 1974, the stone eas identified as an unusually Ni-rich iron meteorite. Clemente Allini donated it to the Civic Natural History Museum of Milan, where the main mass - 479 gr. - is still preserved. DESCRIPTION: The original mass of the iron was 860 gr.The iron is severely alterated on its surface, but still well preserved inside. Etching on a polished surface doesn't show macroscopic Widmanstatten patterns. Electron Microprobe analysis indicate that the iron consists almost entirely of Taenite, with minor plates of Kamacite. Troilite and schreibersite are accessory phases. CLASSIFICATION: Based on mineralogical and chemical data the meteorite is classified as an UNGROUPED ATAXITE. We propose to name it " BARBANIELLO " after the municipality in which it was found. For see a piece of this meteorite go to my collection site and see under Redavalle meteorite, the first name give to this meteorite.
