D. W. Holliday; The origin of penemosaic texture in evaporites of the Detroit River Formation (Middle Devonian) in northern Indiana; discussion of a paper by L. F. Rooney and R. R. French. Journal of Sedimentary Research ; 39 (3): 1256–1258. doi: https://doi.org/10.1306/74D71DFC-2B21-11D7-8648000102C1865D
Much work on nodular sulfate rocks has shown that they are formed by penecontemporaneous growth of gypsum and anhydrite often with a complex early diagenetic relationship within the host sediment, resulting in a wide variety of textures. The penemosaic structures noted by Rooney and French (ibid., v. 38, p. 755-765, 1968) were formed by such a process rather than by wave action and density settling.
