Dall, W.H., 1898, A table of North American Tertiary horizons, correlated with one another and with those of western Europe, with annotations, IN Walcott, C.D., Eighteenth annual report of the United States Geological Survey to the Secretary of the Interior, 1896-1897; Part II, Papers chiefly of a theoretical nature: U.S. Geological Survey Annual Report, 18, pt. 2, p. 323-348., Also published in 1897 as 55th Congress, 2nd session, House Document no. 5


Summary:

Pg. 344, and chart opp. p. 334. Wilmington beds. See Clark, USGS Bull 83, 1891, p. 48-50, also note under E22. [The note under E22 is:] This [the Shark River beds of New Jersey], like the Eocene of North Carolina, is regarded by Harris as newer than that of Maryland and Virginia, which has been included under name Pamunkey by Darton. [Assigned to Claibornian in table opp. p. 334.]
Apparently named from exposures at Wilmington, southeastern coast of NC.
[GNC remark (ca. 1936, US geologic names lexicon, USGS Bull. 896, p. 2345): On p. 48-50 of USGS Bull. 83 W.B. Clark described the Eocene deposits of North Carolina but did not apply a geographic name to them. In region described by Clark the deposits are now divided into Castle Hayne marl (of upper Eocene, Jackson, age) above and Trent marl (lower Miocene) below, both of which were evidently included in "Wilmington beds."
