Gamma ray spectrometry measurements of Ordovician strata at Tumbling Run, Virginia

This dataset includes gamma ray spectrometry measurements from exposed Ordovician mixed carbonate and siliciclastic strata near Tumbling Run, Virginia; a regionally recognized reference section within the central Appalachians. Gamma ray measurements were collected on a continuous assay with a thirty second collection interval by walking one meter from the outcrop face using a GF Instruments Gamma Surveyor Vario handheld gamma-ray spectrometer. The measurements were collected to characterize the radiometric signature of the ~860 feet of outcropping stratigraphy of the Pinesburg Station Dolomite of the Beekmantown Group, New Market Limestone, Lincolnshire Limestone, Edinburg Formation, and the Stickley Run Member of the Martinsburg Formation at this location. These data will also serve as ground truth measurements for published and ongoing airborne radiometric surveys within the region.
