Robert E. Weems
Upon completing his doctoral dissertation at the George Washington
University, Rob joined the USGS in 1978. During his nineteen years with the
USGS, Rob has worked primarily on the stratigraphy of the Atlantic Coastal
Plain in South Carolina, North Carolina, Virginia, and Maryland, on the
stratigraphy of the Newark Supergroup basins from South Carolina through
Connecticut, and on the Salem Plateau in the Ozarks of southern Missouri. In
the course of his stratigraphic work, he has been able to apply his vertebrate
paleontological background toward refining the dating and correlation of
numerous stratigraphic units in the eastern and central United States, and he
also has helped to develop a better understanding of the depositional
environments of many of the stratigraphic units that he has studied. The
results of his work have been documented in more than 60 scientific papers, 15
geologic maps, and 29 abstracts.
