T. Prior in Mineral. Mag. 18 151 In the Rose–Tschermak–Brezina classification of meteorites the intermediate class of stony-irons, in which iron and stony matter occur in approximately equal amounts and to which Maskelyne gave the name siderolites, is divided into (1) siderolites proper..and (2) lithosiderites, comprising the groups of the mesosiderites, grahamites, and lodranites. 1962 B. Mason Meteorites viii. 120 The stony-irons are a minor group of meteorites... They are divided into two major groups according to the nature of the silicate minerals, the pallasites (olivine stony-irons) and mesosiderites (pyroxene-plagioclase stony-irons). 1969 Times 9 Apr. 7/3 Stony-iron meteorites have been found in several Hopewell burial mounds. 1978 D. W. Sears Nature & Origin of Meteorites iii. 73 Stony-iron meteorites are traditionally defined as having approximately equal proportions of stony material and iron. At various times, four groups of stony-iron meteorites have been defined, but since two of these contain only one meteorite each we need here consider only two in any detail: the pallasites and the mesosiderites. < as lemmas |
