Webin meteorite research (Scott et al., 1992; St€offler et al., 1991). Ed’s prowess in the research and development of new ideas was shown by his discovery with colleagues Richard Greenwood and Ian Franchi at the Open University (UK) that the eucrite group of differentiated meteorites does not come from one parent asteroid (Scott et al., 2009). WebHowever, the same minerals are also found, in different proportions, in certain differentiated meteorites, and in addition the observed asteroid spectra do not exactly match those obtained in the laboratory from ordinary-chondrite specimens. Because the ordinary chondrites are the most abundant variety of meteorite falling on Earth today, …
WebPrimitive and Differentiated Meteorites: Asteroidal Achondrites. In Chap. 4 we looked at the most primitive meteorites, the chondrites. We saw that about 85% of all known meteorites fall into this category. The remaining meteorites are achondrites. In the broadest sense the word “achondrites” means “without chondrules.”.
