New Paper In Southeastern Geology About Carolina Bays
The paper is:
Moore, C. R., M. J. Brooks, D. J. Mallinson, P. R. Parham, A. H. Ivetser,
J. K. Feathers, 2016, The Quaternary evolution of Herdon Bay, a
Carolina Bay on the coastal plain of of North Carolina (USA): Implications
for paleoclimate and oriented lake genesis. Southeastern Geology.
vol. 51, no. 4, pp. 145-171. (March 2016)
They found that LiDAR images showed that Herdon Bay, a Carolina Bay
exhibited a regressive sequence of sand rims that partially backfill the
the older portions of this bay. These rims and subsurface data provided
evidence for the episodic migration of this bay by more than 600 meters
to the northwest. Single grain optically stimulated luminescence (OSL)
age estimates indicate that the oldest rim formed about 36.7 +/- 4.1 ka
and the youngest rim formed around 29.6 +/- 3.1 to 27.2 +/- 2.8 ka.
They interpreted these dates as indicating the rim construction and bay
migration was coincident with Marine Isotope Stage 3 through early
Marine Isotope Stage, which was a time of rapid oscillations in climate.
