The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, hydrocarbon plays were defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries.

This data set contains surficial geologic units in the Eastern and CentralUnited States, as well as a glacial limit line showing the position ofmaximum glacial advance during various geologic time periods. Thegeologic units represent surficial deposits and other surface materialsthat accumulated or formed during the past 2+ million years, such assoils, alluvium, and glacial deposits. These surface materials arereferred to collectively by many geologists as regolith, the mantle offragmented and generally unconsolidated material that overlies the bedrockfoundation of a continent.This data set and the printed map produced from it, U.S. Geological Survey(USGS) Geologic Investigation Series I-2789, were based on 31 publishedmaps...

The titanium concentrations were obtained from a data set that is called the "National Geochemical Survey." This data set, as well as its documentation, are available in U.S. Geological Survey Open-File Report 2004-1001 (https://mrdata.usgs.gov/geochem/doc/home.htm). The titanium concentrations were measured in 3,457 samples of stream sediments from the coastal plain of the southeastern United States; this area includes parts of Virginia, North Carolina, South Carolina, Georgia, Florida, and Alabama. The samples were collected between 1975 and 1999 during several field surveys, and the concentrations were measured using inductively coupled plasma-atomic emission spectrometry.
