This dataset contains fault features compiled by the Geological Survey of Alabama, and published as a Web feature service for the National Geothermal Data System. Fields in the Fault Feature Content Model will become XML elements in interchange documents for WMS simple features provided by a node in the USGIN network. Each observation includes a Fault Name, Symbol, and location spatially referenced to EPSG: 4326 (for interoperability). The data contained in the submitted dataset is available as an Access Database (.mdb), Excel Spreadsheet, ESRI service, WMS and WFS service.

This spreadsheet is a compilation of Active Fault features compiled by the United States Geological Survey, courtesy of the Utah Geological Survey. This data is published as a Web feature service for the National Geothermal Data System. The document contains 7 worksheets, including information about the template, instructions on using the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Each feature in an active fault data set (row in this spreadsheet) should be characterized by a unique combination of name, URI, geologic history, slip, locatability and orientation properties, as well as being physically connected or inferred to be connected in the Earth. For mapped active faults ,which are the scope of this scheme, the deformation style is assumed to be brittle (as opposed to ductile). Fields in the data table include FeatureURI, Name, FullName, ParentFeatureURI, Label, Description, Symbol, OtherID, SpecificationURI, FeatureType, GeologicHistory, RepresentativeAgeURI, YoungerAgeURI, OlderAgeURI, IntervalSinceMovement, Shape, ObservationMethod, PositionAccuracyMeters, PositionAccuracy, Displacement, SlipRate, SlipAccumulationInterval, MovementType, MovementSense, DipDirection, DateMostRecentEvent, RecurrenceInterval, TotalSlip, Source and MetadataURI.

Franciscan rocks in The Geysers Geothermal Resources Area (GRA) constitute a greatly deformed and chaotic assemblage of rocks known as melange which, under natural conditions, poses problems to slope stability. Unstable conditions inherent in the melange are accentuated by the steepness of slopes, chemical alteration of the rocks, and numerous faults and shear zones. Adverse effects that may be .experienced- with development of melange terrain can, however, be mitigated if potential problem areas are recognized before development begins and if good engineering geology·and engineering practices are followed.

Thermal waters produced from large oil fields are currently the most important geothermal resources in Los Angeles County. Assuming that various technological and economic considerations are favorable, many of these fields are promising sources of heat for diverse applications outside the field operations. Otherwise, the County does not appear to have any large, near-surface geothermal resources.

This report presents the results of geothermal resources investigations conducted in the Sonoma Valley area of California by the California Department of Conservation's Division of Mines and Geology. Included are the results from separate studies performed in two preceding years, of the southern and central Sonoma Valley area (1981-82) and the northern Sonoma Valley area (1982-83); also included are the results of a shallow temperature drilling program and general "wrap up" assessment of the resource conducted in 1983-84. The study was undertaken to learn more about the known low-temperature (20° - 90°C) geothermal resource in this area and to assess the potential of the resource for development and use by the local community.
