RI47 Ages of the Bethany, Beaverdam, and Omar Formations of Southern Delaware

RI47 Ages of the Bethany, Beaverdam, and Omar Formations of Southern Delaware
Publication Type:
Report of Investigation
Publication Date:
Feb 1990
Authors:
Groot, J.J., Ramsey, K.W., Wehmiller, J.F.
Abstract:

The microflora of the Bethany formation and the lower part of the Beaverdam Formation is characterized by a Quercus-Carya assemblage, very few non-arboreal pollen, and Pterocarya and Sciadopitys as exotic constituents. This assemblage has much in common with that of the Brandywine Formation of Maryland and the Eastover Formation of Virginia which are of late Miocene or early Pliocene age. The environment of deposition of the Bethany was probably deltaic, and that of the lower Beaverdam fluviatile.
