HUTCHISON R. (2004) Meteorites: A Petrologic, Chemical, and Isotopic Synthesis (Cambridge Planetary Science Series, pp. 506).
p. 56: "Chondrules are objects that were wholly or partly molten before or during the accretion period(s) that led to the formation of chondrites". NORTON O.Richard. (2002) The Cambridge Encyclopedia of Meteorites, Glossary, p. 342: "Spherical to subspherical millimeter-sized bodies of igneous origin in ordinary chondrites, carbonaceous chondrites (except CI), enstatite chondrites and R chondrites". McSWEEN H.Y. (1999) Meteorites and Their Parent Planets (Cambridge University Press, Glossary, p. 288): "Millimeter-sized spherule of rapidly cooled silicate melt, found in abundance in chondritic meteorites." WASSON J.T. (1974) Meteorites: Classification and Properties (Springer-Verlag, Berlin. 316 pp., Glossary, pp. 242-243): "Although used by some authors to designate any mm-sized spheroidal body in a meteorite, usage should be restricted to those bodies which formed as molten droplets by the same process or processes which produced the chondrules observed in chondrites. Spheroidal bodies which have not been molten, or which may have formed by processes other than those which formed the chondrite chondrules, should be called chondrule-like objects."
