This spreadsheet is a compilation of Aqueous Spring Chemistry observations compiled by the Arizona Geological Survey, published as a Web feature service for the National Geothermal Data System. The document contains 15 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view), An Analyte Dictionary and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Data from 116 springs are included.

These layer files contain the symbology for portrayal of geothermal features in ArcMap. For the Borehole Temperatures and thermal springs, the color ramp ranges from green (cool) to red (hot) for each feature. For the active faults legend, the FGDC symbology was used (with additions further specifying activity during the early Quaternary). For the volcanic features, well headers and well log information, an arbitrary symbol was chosen.

Twenty-Seven thermal springs in Arizona, New Mexico, and Utah were sampled for detailed chemical and isotopic analysis. Sampling in New Mexico and Utah was confined to known geothermal resource areas as designated by the U.S. Geological Survey.

Thermal springs are widely distributed throughout the world but are most numerous in areas in which there has been volcanic activity in late geologic time. A review of the available literature has revealed much information on the location of the springs, the temperature of the water, the rate of flow, the chemical character of the water and evolved gases, and the uses made of the water. All such information has been tabulated by countries or geographic areas and is present in the first part of this report. Accompanying the tabulated data for each country or geographic area is a brief description of the geology and a map showing the location of the springs. The second part of the report consists of a list of references, some annotated briefly, to the literature on thermal springs. The references are grouped by countries or geographic areas and within each group are arranged in alphabetical order by author. However, for ease of citation throughout the report, the references have been assigned consecutive numbers.
