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.
