This volume focuses on the geometry, kinematic development, and origin of regional segmentation structures within the basin and range province of Western North America. Contributions range from analysis of individiual structures to broad regional syntheses, including a map of basin and range structures and tilt domains. Several papers discuss the implications of regional segmentation structures in assessing seismic hazards, hydrocarbon and mineral resources, and ground-water supplies.

This report (269 pages, 4 plates) presents hydrogeologic, groundwater-monitoring, and hydrochemical studies by the Utah Geological Survey (UGS) in Snake Valley, Tule Valley, and Fish Springs Flat in Millard and Juab Counties, west-central Utah. Data From the newly established UGS groundwater-monitoring network establish current baseline conditions, and will help quantify the effects of future variations in climate and groundwater pumping. New hydrochemical data show that groundwater quality is generally good, major-solute chemistry varies systematically from recharge to discharge areas, and suggest that most groundwater was recharged over one thousand years ago, implying low recharge rates and/or long or slow flow paths. Two aquifer tests yield estimates of transmissivity and storativity for the carbonate-rock and basin-fill aquifers. Variations in the potentiometric surface, hydrogeology, and hydrochemistry are consistent with the hypothesis of regional groundwater flow from Snake Valley northeast to Tule Valley and Fish Springs. Collectively, our work delineates groundwater levels, flow, and chemistry in Snake Valley and adjacent basins to a much greater degree than previously possible, and emphasizes the sensitivity of the groundwater system to possible increases in groundwater pumping.

The objective of this report is to summarize U.S. Department of Energy (DOE) supported studies in the Dixie Valley geothermal area and to relate the results of those studies to other, non-DOE-supported studies that have been done in the valley during the past 40 to 50 years. This compilation of past research includes new analysis resulting in a more in-depth understanding of the geothermal system in Dixie Valley. The focus is on the basin geology and structure, thermal regime, and geothermal system geochemistry. Reservoir studies are briefly discussed.

This report (185 pages and 2 plates) presents new and compiled geologic, geophysical, hydrologic, and hydrochemical data to delineate the regional ground-water flow system in Curlew Valley. Decreased precipitation combined with increased agricultural pumping in the central part of Curlew Valley since the late 1960s caused a steady decline in discharge at the Locomotive Springs complex. The report includes a compiled geologic map of the Curlew Valley surface-drainage basin at 1:100,000 scale and new geologic and hydrochemical data.

The Oligocene and Miocene Epochs comprise the most important phases in the Cenozoic global cooling that led from a greenhouse to an icehouse Earth. Recent major advances in the understanding and time-resolution of climate events taking place at this time, as well as the proliferation of studies on Oligocene and Miocene shallow-water/neritic carbonate systems, invite us to re-evaluate the significance of these carbonate systems in the context of changes in climate and Earth surface processes. Carbonate systems, because of a wide dependence on the ecological requirements of organisms producing the sediment, are sensitive recorders of changes in environmental conditions on the Earth surface. The papers included in this Special Publication address the dynamic evolution of carbonate systems deposited during the Oligocene and Miocene in the context on climatic and Earth surfaces processes focusing on climatic trends and controls over deposition; temporal changes in carbonate producers and palaeoecology; carbonate terminology; facies; processes and environmental parameters (including water temperature and production depth profiles); carbonate producers and their spatial and temporal variability; and tectonic controls over architecture. This book is part of the International Association of Sedimentologists (IAS) Special Publications. The Special Publications from the IAS are a set of thematic volumes edited by specialists on subjects of central interest to sedimentologists. Papers are reviewed and printed to the same high standards as those published in the journal Sedimentology and several of these volumes have become standard works of reference.
