Abstract
This atlas is a product of the Great Basin Regional Aquifer-System Analysis (RASA), a study that began in 1981. The study is part of a U.S. Geological Survey program for evaluating regional aquifer systems nationwide. A regional aquifer system is defined as “an areally extensive set of aquifers which are linked in some way, such as hydraulically or economically” (Harrill and others, 1983, p. 2). The purpose of the Great Basin RASA is to evaluate aquifer system in the Great Basin by developing a better understanding of recharge and discharge processes, delineating individual ground-water flow systems, and developing mathematical models of representative flow systems. Harrill and others (1983) provide a more complete background of both the national RASA program and the Great Basin RASA.
The purpose of this atlas is to delineate and describe the major hydrogeologic units in the Great Basin region and to identify those units that (1) constitute regional aquifers or (2) act as barriers to the movement of ground water. The scope of this atlas, however, is limited to a brief geologic overview of the Great Basin: lithology and areal extent of units, major structural features, and influence of tectonic events. In addition, the water-bearing characteristics of each unit are briefly summarized.
This atlas is Chapter A of the three-part Hydrologic Atlas series. Chapter B shows ground-water levels in the Great Basin region, and Chapter C shows inferred directions of ground-water flow and individual flow systems.
