Regional stratigraphic cross sections of Cretaceous rocks from east-central Arizona to the Oklahoma Panhandle Regional stratigraphic cross sections of Cretaceous rocks from east-central Arizona to the Oklahoma Panhandle
Sedimentary rocks of Cretaceous age along Transect DD'' in eastern Arizona, northern New Mexico, southern Colorado, and western Oklahoma consist mainly of sandstone, siltstone, shale, limestone, and bentonite. They accumulated as sediments in continental, nearshore marine, and offshore marine environments on the west side of a north-trending epicontinental sea. The rocks record...
Magnetic anomaly map of North America Magnetic anomaly map of North America
This digital Magnetic Anomaly database and map for the North American continent is the result of a joint effort by the Geological Survey of Canada (GSC), U.S. Geological Survey (USGS), and Consejo de Recursos Minerales of Mexico (CRM). The database and map represent a substantial upgrade from the previous compilation of Magnetic Anomaly data for North America, now over a decade old...
Atlas of natural hazards in the Hawaiian coastal zone Atlas of natural hazards in the Hawaiian coastal zone
The purpose of this report is to communicate to citizens and regulatory authorities the history and relative intensity of coastal hazards in Hawaii. This information is the key to the wise use and management of coastal resources. The information contained in this document,we hope,will improve the ability of Hawaiian citizens and visitors to safely enjoy the coast and provide a strong...
Backscatter Intensity and Sun-Illuminated Sea Floor Topography of Quadrangles 1 and 2 Backscatter Intensity and Sun-Illuminated Sea Floor Topography of Quadrangles 1 and 2
The Great South Channel separates the western part of Georges Bank from Nantucket Shoals and is a major conduit for the exchange of water between the Gulf of Maine to the north and the Atlantic Ocean to the south. Water depths range mostly between 65 and 80 m in the region. A minimum depth of 45 m occurs in the east-central part of the mapped area, and a maximum depth of 100 m occurs in...
Geologic and aeromagnetic maps of the Fossil Ridge area and vicinity, Gunnison County, Colorado Geologic and aeromagnetic maps of the Fossil Ridge area and vicinity, Gunnison County, Colorado
This data set includes a GIS geologic map database of an Early Proterozoic metavolcanic and metasedimentary terrane extensively intruded by Early and Middle Proterozoic granitic plutons. Laramide to Tertiary deformation and intrusion of felsic plutons have created numerous small mineral deposits that are described in the tables and are shown on the figures in the accompanying text...
