1919 Amer. Jrnl. Sci. 197 322 Optical studies of the reddish, scaly crystals called rubinglimmer and lepidocrocite, led Lacroix to propose that they be classed together as lepidocrocite and separated from goethite, with which they had formerly been identified.

1944 C. Palache et al. Dana's Syst. Mineral. (ed. 7) I. 644 The name goethite properly belongs to the species here described, since the name was originally given by Lenz to the material from Eiserfeld now known to be lepidocrocite. Goethite, however, is in general use to designate the compound HFeO₂.

1951 Amer. Mineralogist 36 31 Lepidocrocite has the hydrogen atom in a discrete OH group... Hence the decomposition of lepidocrocite occurs at a lower temperature than goethite.

1967 New Scientist 13 July 92/3 Professor Lowenstam has discovered that some chitons have a second iron mineral in their teeth—lepidocrocite.

1971 R. J. Gettens Two Early Chinese Bronze Weapons iv. 23 The iron blade which served as the cutting edge has been drastically altered by corrosion... X-ray powder diffraction analysis of samples of rust showed that it consists of two hydrated iron oxides, goethite..and lepidocrocite.
