The report also provides an integrated geologic and geophysical framework for ground-water investigations in the Las Vegas region. Geologic and geophysical mapping conducted for this report helped to identify faults, fractures, and other permeable zones that are pathways for ground-water flow and to determine the distribution of potential aquifers and ground-water barriers.

The publication contains two parts: the first, part A, includes the geologic map of the Las Vegas quadrangle, cross sections, and text with description of map units and discussion of the stratigraphic and structural framework of the map area; the second part, part B, includes isostatic gravity, aeromagnetic, and gravity inversion maps, geophysical cross sections of Las Vegas and Pahrump Valleys, and text describing the geophysical framework of the map area. The integration of geologic and geophysical information contained in the report offers a unique opportunity to apply basic geoscience techniques to help solve urban growth issues in this arid population center."
