Using the GSSEARCH access software contained on the CD-ROM disc, users can retrieve the data by specifying sample type, quadrangle, latitude, longitude, element, element concentration range, or combinations of these and other criteria. Data may be output to the user's system in several different formats for data analysis.  aSystem requirements: IBM PC or compatible with math coprocessor; 640Kb RAM (at least 540Kb free memory); MS- or PC-DOS 5.0 or later; Microsoft MSCDEX 2.1 or later; hard disk; VGA graphics card; VGA color monitor; CD-ROM drive with ISO 9660 software driver; Microsoft compatible mouse (highly recommended).  aSamples from 319 quadrangles (1 degree x 2 degrees) beginning in 1976 and ending in 1980; four main sample types represented: stream sediment, soil, surface water, and ground water. Each sample analyzed for uranium and as many as 58 other elements including sulfate. 0aUranium oreszUnited StatesxDababases.2Local 0aCD-ROM Fed.
