Book Description
The authors have synthesized 16 years of geological and geophysical studies which document an 85-km-wide impact crater buried 500 m beneath Chesapeake Bay in south eastern Virginia, USA. In doing so, they have integrated extensive seismic reflection profiling and deep core drilling to analyze the structure, morphology, gravimetrics, sedimentology, petrology, geochemistry, and paleontology of this submarine structure. Of special interest are a detailed comparison with other terrestrial and extraterrestrial craters, as well as a conceptual model and computer simulation of the impact. The extensive illustrations encompass more than 150 line drawings and core photographs.

Book Description
"The Chesapeake Bay impact structure is a well-documented example of a small group of multi-layer, marine-target impacts formed in continental shelves or beneath epeiric seas. New sedimentological and stratigraphical data and results--mainly from Chesapeake Bay brim cores (Watkins School, Langley, and Bayside)--are compared to and compiled with key crater core data"--

Book Description
From the sandstone ridges and shale valleys of western Maryland to the sand dunes and tidal estuaries on Delaware's coast, the geologic features of the Mid-Atlantic region include a diverse array of rocks and landforms assembled during more than 1 billion years of geologic history. The book's introduction presents an overview of the geologic history of Maryland, Delaware, and Washington, D.C., and 35 road guides discuss the landforms and rocks visible from a car window, along bike paths, and at nearby waysides and parks, including Chesapeake Ohio Canal National Historic Park, Assateague Island National Seashore, Rock Creek Park, and Cape Henlopen State Park.

Book Description
Thirty-five million years ago, a meteorite three miles wide and moving sixty times faster than a bullet slammed into the sea bed near what is now Chesapeake Bay. The impact, more powerful than the combined explosion of every nuclear bomb on Earth, blasted out a crater fifty miles wide and one mile deep. Shock waves radiated through the Earth for thousands of miles, shaking the foundations of the Appalachians, as gigantic waves and winds of white-hot debris transformed the eastern seaboard into a lifeless wasteland. Chesapeake Invader is the story of this cataclysm, told by the man who discovered it happened. Wylie Poag, a senior scientist with the U.S. Geological Survey, explains when and why the catastrophe occurred, what destruction it caused, how scientists unearthed evidence of the impact, and how the meteorite's effects are felt even today. Poag begins by reviewing how scientists in the decades after World War II uncovered a series of seemingly inexplicable geological features along the Virginia coast. As he worked to interpret one of these puzzling findings in the 1980s in his own field of paleontology, Poag began to suspect that the underlying explanation was the impact of a giant meteorite. He guides us along the path that he and dozens of colleagues subsequently followed as--in true scientific tradition--they combined seemingly outrageous hypotheses, painstaking research, and equal parts good and bad luck as they worked toward the discovery of what turned out to be the largest impact crater in the U.S. We join Poag in the lab, on deep-sea drilling ships, on the road for clues in Virginia, and in heated debates about his findings. He introduces us in clear, accessible language to the science behind meteorite impacts, to life and death on Earth thirty-five million years ago, and to the ways in which the meteorite shaped the Chesapeake Bay area by, for example, determining the Bay's very location and creating the notoriously briny groundwater underneath Virginia. This is a compelling work of geological detective work and a paean to the joys and satisfactions of a life in science. Originally published in 1999. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
From the Eastern Shore to Cumberland Gap, Virginia stretches across five distinct regions, each home to unique and amazing geology. In the Coastal Plain's wedge of fossil-rich sediments, a meteor impact crater"¬‚¬"the sixth largest on Earth"¬‚¬"helped determine the location of Chesapeake Bay. The Piedmont begins at the Fall Line, the series of East Coast waterfalls that mark the upstream limit to ship navigation, such as Belle Else in Richland, where the turbulent James River erodes potholes in the Petersburg Granite. Rising up from the rolling hills of the Piedmont, the Blue Ridge forms the spine of the state, its hard basalt and gneisses on display at Shenandoah National Park. Farther west, limestones in the Valley and Ridge are riddled with caves and sinkholes, with dissolution forming one of the wonders of the world at Natural Bridge State Park. Along the very western edge of the state is the Appalachian Plateau, where the No. 3 coal, know as America's Favorite Fuel was extracted from the historic Pocahontas Mine. Virginia Rocks! is part of the state-by-state Geology Rocks! series that introduces readers to some of the most compelling and accessible geologic sites in each state. Author Albert Dickas has picked 50 of the best sites in Virginia for discussing the enormous variety of rocks, minerals, and landforms created over the course of the states more than 1 billion years of geologic history.

Book Description
This text commences with the history of tektites, from mediaeval China, through finds in Czechoslovakia in the 18th century and Darwin's description while on the Beagle, to 20th-century finds in South East Asia, the Ivory Coast and the USA. The four major strewn fields are described, followed by their extension by deep sea finds of microtektites and the recognition of irregular, large layered tektites in SE Asia.
