mesosideriten.

1868 Geol. Mag. 5 76 Meteorites have long since been arranged under two great divisions, the irons and the stones... In examining a certain number of these masses it has been thought convenient by some to establish a third, or intermediate division, to which the names of Mesosiderites, Lithosiderites, or of Siderolites, have been given.

1918 G. 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.

1929 W. F. Foshag in G. P. Merrill Minerals from Earth & Sky ii. vii. 96 Of the thirty-one known stony irons variously classed as lodranites, pallasites, and mesosiderites..there were seen to fall but five or..sixteen per cent.

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).

1997 Meteoritics & Planetary Sci. 32 360/2 Mesosiderites appear to contain more impact melts than any other group of minerals.
