1914 Eakle & Rogers in Amer. Jrnl. Sci. 187 263 The writers take pleasure in naming it wilkeite in honor of R. M. Wilke, who as a mineral collector and dealer has done much to advance the science of mineralogy.

1937 Amer. Mineralogist 22 977 It has become necessary to investigate the substitutions of the sort found in wilkeite.

1975 Nature 27 Feb. 722/1 Among the minerals described to have any significant degree of P(V)–Si(IV) partial substitution are viseite, nagatelite and wilkeite, an apatite with partial SiO₄ + SO₄ substitution for PO₄.

1982 Amer. Mineralogist 67 90 Wilkeite is not a valid mineral species, since it is only one of many solid solutions involving the six end-members fluorapatite, hydroxyapatite, chlorapatite, fluorellestadite, hydroxyellestadite, and chlorellestadite.
