Description

This gigapan is of the Balls Bluff Siltstone. It is upper Triassic in age. This road cut exposes the middle to upper part of the formation. This is likely the fluvial and deltaic sandstone and siltstone member described by Scott Southworth, William C. Burton, J. Stephen Schindler, and Albert J. Froelich in their 2006 geologic map of Loudoun County, Virginia. It is basin sediment that filled in a failed rift during the rifting of Pangea. It is part of the Newark Supergroup which is a group of sedimentary basins that extend from Newark New Jersey to South Carolina. In this area it is lightly metamorphosed. This image is was taken facing south near exit 4. The bedding dips to the west.
