Lucy Edwards
Lucy Edwards is a Scientist Emeritus at the Florence Bascom Geoscience Center.
Lucy E Edwards focuses her research on the stratigraphy of the Atlantic and Gulf Coastal Plains. Her specialty is dinoflagellates (a type of algae), and she studies their fossil cysts for what they reveal about the time and environment of deposition and how they came to be preserved in the fossil record. She also specializes in stratigraphic nomenclature and methods of stratigraphic correlation.

Supplemental materials for the ICDP-USGS Eyreville A, B, and C core holes, Chesapeake Bay impact structure: Core-box photographs, coring-run tables, and depth-conversion files Supplemental materials for the ICDP-USGS Eyreville A, B, and C core holes, Chesapeake Bay impact structure: Core-box photographs, coring-run tables, and depth-conversion files
During 2005-2006, the International Continental Scientific Drilling Program and the U.S. Geological Survey drilled three continuous core holes into the Chesapeake Bay impact structure to a total depth of 1766.3 m. A collection of supplemental materials that presents a record of the core recovery and measurement data for the Eyreville cores is available on CD-ROM at the end of this volume...

Impact effects and regional tectonic insights: Backstripping the Chesapeake Bay impact structure Impact effects and regional tectonic insights: Backstripping the Chesapeake Bay impact structure
The Chesapeake Bay impact structure is a ca. 35.4 Ma crater located on the eastern seaboard of North America. Deposition returned to normal shortly after impact, resulting in a unique record of both impact-related and subsequent passive margin sedimentation. We use backstripping to show that the impact strongly affected sedimentation for 7 m.y. through impact-derived crustal-scale...

Site Report for USGS Test Holes Drilled at Cape Charles, Northampton County, Virginia, in 2004 Site Report for USGS Test Holes Drilled at Cape Charles, Northampton County, Virginia, in 2004
The U.S. Geological Survey drilled two test holes near Cape Charles, Virginia, during May and June 2004, as part of an investigation of the buried, late Eocene Chesapeake Bay impact structure. The first hole is designated as the USGS-Sustainable Technology Park test hole #1 (USGS-STP1). This test hole was abandoned at a depth of 300 ft; cuttings samples were collected, but no cores or...

Origin and emplacement of impactites in the Chesapeake Bay impact structure, Virginia, USA Origin and emplacement of impactites in the Chesapeake Bay impact structure, Virginia, USA
The late Eocene Chesapeake Bay impact structure, located on the Atlantic margin of Virginia, may be Earth's best-preserved large impact structure formed in a shallow marine, siliciclastic, continental-shelf environment. It has the form of an inverted sombrero in which a central crater ∼40 km in diameter is surrounded by a shallower brim, the annular trough, that extends the diameter to...

A new species of Pentadinium from Eastern Anatolia, Turkey, Pentadinium galileoi A new species of Pentadinium from Eastern Anatolia, Turkey, Pentadinium galileoi
The new gonyaulacoid dinoflagellate Pentadinium galileoi Sancay et al., sp. nov. from the Oligocene-Lower Miocene sediments of Eastern Anatolia has been identified. It is spherical, chordate with prominant discoidal cingulum and distally furcate apical, sulcal, and antapical processes. It has a type P(3???) archeopyle, and periarcheopyle is larger than endoarcheopyle. Tabulation is...
