Tripping from the Fall Line
"Emanating from the Fall Line city of Baltimore, site of the 2015 GSA Annual Meeting, these trips reflect the diversity of geological features in the mid-Atlantic region including the Piedmont, Appalachian Mountains, and Coastal Plain, and the importance of geology on the development and construction of the Baltimore-Washington, D.C., metropolitan area"--
PaleoAmerican Archaeology in Virginia
This book is a full-color study of over 500 pre-Clovis stone artifacts of Virginia. With the 22K-year date of the Cinmar bipoint in Virginia, there is ample evidence of artifact classes that are older than Clovis. Over 50 tool types are illustrated and discussed. Artifact single-site collections are documented. The book argues the differences between Holocene biface technology with the blade and core technology of the Pleistocene era. The requirements for identifying Pleistocene artifacts is presented, such as platforms, remaining cortex, and invasive retouch. They are presented in a tool model. Major stones, namely jasper, are discussed as a lithic determinism. The east coast distribution is presented for various tool types. Additionally, as a major focus, cross-Atlantic flake/blade identical tools from Europe are illustrated with Middle Atlantic artifacts. Artifact ergonomics, such as right-left handed tools, hypothetical tool center, are argued. Structural and functional axis are shown and described on how to identify them on tools. Overall, this book presents an initiating view of the archaeology needed to study Pleistocene era artifacts on the American east coast.
The River Where America Began
From the establishment of the first permanent English colony at Jamestown in 1607 to the fall of Richmond in 1865, the James River has been instrumental in the formation of modern America. It was along the James that British and Native American cultures collided and, in a twisted paradox, the seeds of democracy and slavery were sown side by side. The culture crafted by Virginia's learned aristocrats, merchants, farmers, and frontiersmen gave voice to the cause of the American Revolution and provided a vision for the fledgling independent nation's future. Over the course of the United States' first century, the James River bore witness to the irreconcilable contradiction of a slave-holding na...
The ICDP-USGS Deep Drilling Project in the Chesapeake Bay Impact Structure
"In 2005 and 2006, an international deep drilling project, conceived and organized under the auspices of the International Continental Scientific Drilling Program and the U.S. Geological Survey, continuously cored three boreholes to a total depth of 1.766 km near the center of the Chesapeake Bay impact structure in Northampton County, Virginia. This volume presents the initial results of geologic, petrographic, geochemical, paleontologic, geophysical, hydrologic, and microbiologic analyses of the Eyreville cores, which constitute a step forward in our understanding of the Chesapeake Bay impact structure and marine impact structures in general. The editors have organized this extensive volume into the following sections: geologic columns; borehole geophysical studies; regional geophysical studies; crystalline rocks, impactites, and impact models; sedimentary breccias; post-impact sediments; hydrologic and geothermal studies; and microbiologic studies. The multidisciplinary approach to the study of this impact structure should provide a valuable example for future scientific drilling investigations."--Publisher's description.
