Description
English: Plate XLIII from The Geology of the Richmond Basin published by USGS, which has the following caption:
Plan and section of the Deep Run Basin. (After Clifford.)
The text of the report refers to the figure as follows:
Between the southern end of the Springfield arеа (the Deep Run Basin of recent reports, see Pl. XLIII, by Clifford) and the main Richmond area lies the shallow valley of Flat Branch, a stream flowing almost due south into Deep Run at an average distance of 1 mile from the eastern margin of the main coal-field. In the bottom of this valley, both north and south of the Quiocassin road, and particularly along the side of that road for a distance of 300 feet in either direction, inclined strata may be seen, which recall the neighboring Mesozoic beds. On the west side of the stream shales and granitic sandstones dip gently east, while on the east side, about 300 feet beyond the little church, are pebbly arkose deposits dipping 15° to the west, along with beds whose decomposed surface aspect is that of clay. The syncline thus plainly indicated is the only evidence directly obtainable concerning the structure of this small area.
About half a mile north of the Quiocassin road sandstones and shales, dipping westward, crop out along the eastern margin of this area. A shallow pit sunk in the beds failed to reach deposits of coal. West of this locality granitic sandstones occur in the stream bed. The area has a maximum width of perhaps half a mile and a length north and south of three-fourths of a mile, being continued south of the road above named, where pits have been sunk in the search for coal. Whether or not this area connects southwestward with the main basin can not well be determined on account of alluvium.
On Major Hotchkiss's Geological Map of Virginia and West Virginia, the Deep Run Basin (see Clifford's map, Pl. XLIII) is mapped as continuous through this tract, or near its site, into the main basin. Daddow's map carried the Springfield area southwestward nearly to the place of the Flat Branch area; but Russell 3 omits it. As indicated above, no evidence of the present connection of these areas was discovered in this survey.
