Quaternary geologic map of the Chesapeake Bay 4 degrees x 6 degrees quadrangle, United States
The Quaternary Geologic Map of the Chesapeake Bay 4? x 6? Quadrangle
was mapped as part of the Quaternary Geologic Atlas of the United States.
The atlas was begun as an effort to depict the areal distribution of
surficial geologic deposits and other materials that accumulated or
formed during the past 2+ million years, the period that includes all
activities of t

Reconnaissance geologic map of the Sangre de Cristo Wilderness Study Area, south-central Colorado
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine the mineral values, if any, that may be present. Results must be made available to the public and to be submitted to the President and Congress. This report presents the results of geologic studies in the Sa
Sedimentologic and stratigraphic framework of the upper part of the Fort Union Formation, western Powder River basin, Wyoming
The purpose of this study is to describe the stratigraphy and interpret the environments of deposition in the upper part of the Paleocene Fort Union Formation. Of all the lithofacies present within the study area, sandstone is the most dominant and makes up most of the upper part of the Fort Union Formation along the western edge of the Powder River basin, Wyoming. This sandstone lithofacies occur
Seismicity map of the state of Florida
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Florida, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Florida.
