BRINGING THE MID-ATLANTIC REGION TO THE LIGHT: A SUMMARY OF PUBLISHED LUMINESCENCE AGES (OSL, IRSL, TL) FROM THE AREA, WHAT WE HAVE LEARNED AND NEW UTILITIES OF THE TECHNIQUE IN REGIONAL GEOMORPHOLOGY AND ARCHAEOLOGY
We present a review of the past applications of luminescence dating in the Mid-Atlantic region and evaluate ways in which it could be more fully utilized. In addition, we will provide examples of best sampling practices across a variety of geomorphic settings and elaborate on innovative applications of OSL to cultural materials (i.e. pottery). Mainly, luminescence dating has been applied to sandy quartz-rich Coastal Plain sediments east of the Fall Line- escarpment separating the Piedmont uplands from the Coastal Plain. OSL has been particularly useful in dating organic-poor and enigmatic coastal and near-shore deposits, and refining changes in relative sea level over the last glacial cycle (~160ka) (i.e. Lamothe et al., 2012; DeJong et al., 2015). Current research that applies luminescence dating to fluvial terraces and soil stratigraphy is underway, though it is mainly focused in and around the tectonically derived sediments of the central VA seismic zone in the Piedmont (i.e. Carter 2015; Malenda, 2015). Examples and recommendations for sampling will be provided in this presentation along with discussion of what to avoid when collecting samples for OSL/IRSL dating.
