Summary

Description
English: Plate XXXIII from The Geology of the Richmond Basin published by USGS, which has the following caption:
Contact of Newark shales and gneiss on the western border (of the Richmond Basin) south of Mosley Junction. Looking west. Shales on left of bush, gneiss on right.
The text of the report refers to the figure as follows:
The angle south of Mosley Junction.—The abrupt indentation in the outline of the basin which is thus produced about 1 1/2 miles south of Mosley Junction is not represented on the older maps. The extension of the Newark system west of Skinquarter Creek is based upon the occurrence of decomposed sandstones found within the field adjacent to that stream and in line with the westerly strike of the Newark strata on the Irwin Bass place. The contact of the red shales and sandy beds of the Newark with the underlying gneisses at this latter locality, near a barn, is shown in Pl. XXXIII, a photographic view which illustrates the indifferent way in which these two types of rocks weather and erode.
