Summary
The North Carolina Geological Survey (NCGS) was awarded a succession of STATEMAP Grants to map Coastal Plain deposits in the vicinity of the Surry Paleoshoreline complex. This area includes Fountain, Falkland, Farmville and Walstonburg quadrangles, and portions of Pitt, Greene, Wilson and Edgecombe counties. The Surry paleoshoreline is along-strike from Trail Ridge. NCGS maps from the known to the unknown; hence the area for detailed mapping was chosen because a significant amount of high-quality subsurface data already existed in the same area because of the EPA 319h Grants awarded to NCGS. NCGS has a small drill rig called a Geoprobe, that it uses to collect continuous core samples through Pliocene and Pleistocene deposits using the discrete sampling method. Thus far, NCGS has drilled 213 coreholes with the geoprobe, and collected 8,181 ft of unconsolidated core. Maximum penetration depth is 72 ft.

Purpose
Geoprobe cores were collected to better characterize the shallow, subsurface stratigraphy of the Coastal Plain in the vicinity of the Surry Paleoshoreline complex in eastern North Carolina. Core collection supports defining stratigraphy for geologic maps of the Coastal Plain and identifying critical mineral deposits.
