1912 J. E. Wolff in Amer. Jrnl. Sci. 184 476 Although it seems hardly permissible to add a new name to the forty or fifty now found under the chlorite group, yet the purity of this material, its peculiar chemical composition and the certainty that it will be available in large quantity, perhaps justifies the name of ‘Sheridanite’, from the county [in Wyoming] in which it occurs.
1967 Canad. Mineralogist IX. 30 The fine white material in the core of the specimen from Zlatoust, Russia... This material gave an extremely sharp chlorite x-ray pattern. The structural formula..classes it as a sheridanite, as defined by Foster (1962).
