Summary

Description
English: Plate XXXIV from The Geology of the Richmond Basin published by USGS, which has the following caption:
Faults in gneiss at Cornwallis Hill, Boscabel. Looking north.
The text of the report refers to the figure as follows:
The Cornwallis Hill fault-block.—It is clear, from an examination of the neighboring exposures, that Cornwallis Hill, between Manakin and Boscabel Ferry, is a fault-block of the pre-Newark crystalline rocks, left standing up in the crushed and broken sediments of the Richmond basin. This block wedges out south of the river, disappearing beneath the surface of the Newark beds. It appears to have been tilted westward, the coal shales having been thrown down on its eastern face (see fig. 102, p. 467, and Pl. XXXV).
In the quarry opened on the bank of the James River faults may be seen dipping steeply east in the block (see Pl. XXXIV).
