Vermillion is the largest member of a small group called pyroxene pallasites. (Type: Pallasite Class: Pyroxene-rich) A mass of 34.36kg was found in1991, May by M. and G.Farrell while planting in a grain field near the Black Vermillion River, Kansas, USA.
IJ.N.Grossman, Met. Bull. 80, MAPS, 1996, 31, p.A179. A pallasite, that contains abundant orthopyroxene and differs from main group and Eagle Station pallasites in trace element, and oxygen isotopic composition; forms a new grouplet of pyroxene pallasites together with Y 8451, J.S.Boesenberg et al., Meteoritics, 1995, 30, p.488 (abs.). REE abundances in minerals, the metal has a fine octahedrite texture and contains 7.5% Ni, 44ppm Ga, 1.9ppm Ir, J.S.Boesenberg et al. [loc. cit.]. Analysis, similar to Elton, better to be classified as an ungrouped iron because of the low silicate content, B.-G.Choi and J.T.Wasson, LPSC, 1996, 27, p.223 (abs.). Petrologic, trace element and oxygen isotopic study, J.S.Boesenberg et al., MAPS, 2000, 35, p.757. Another classification: an ungrouped silicated iron related to the IAB complex, J.T.Wasson and G.W.Kallemeyn, GCA, 2002, 66, p.2445. Meteorite data copied from MetBase 7.0 for Windows.
