摘要:

ABSTRACTThe classificational distribution of the 1,258 meteoritic falls of the world recorded in Coulson's “A Catalogue of Meteorites” (1940)2is studied. The essence of the paper is contained in 2 tables entitled respectively, “Classes of Meteorites and Representative Falls” and “The Classificational Distribution of the Meteoritic Falls of the World.” The system of classification employed is the Rose‐Tschermak‐Brezina system, with the several modifica

摘要:

ABSTRACTThis paper consists essentially of 3 tables: Table 1, 38 sideritic and siderolitic falls, of which the observation appears to be authentic; Table 2, 18 such falls, whose observation is doubtful or improbable; and Table 3, 7 such falls, so recently reported to have been witnessed as to call for further information, either to confirm or to disprove their reputed observation. The falls, especially those of Table 1, are briefly discussed, and the article ends with a recital of the criteria that may be used to determine whether or not a meteorite—iron or stone—was seen to f

摘要:

ABSTRACT AND INTRODUCTIONIn the first column of the following table are presented some symbols that the writer has found convenient in classifying meteoritesetc. and that he would recommend to other workers. The majority of these symbols stand for various classes in the Rose‐Tschermak‐Brezina system of meteoritic classification1and are accordingly but revisions of the rather unsatisfactory symbols already in use, while a few are innovations. In the second column of the table is given in each case the corresponding old symbol2(if such exists) and in the third and last, the term that the preceding symbol or symbols characterize. It is recommended furthermore that all of the symbols in the forenamed system, other than those enumerated in the second column of the accompanying table, be left unchanged until such time as the whole system of classification may be revi
