Aerial radiometric and magnetic survey: Marysvale detail survey, Richfield National Topographic Map sheet, Utah. Volume III. Magnetic and ancillary stacked profile data. Final report

The results of the analyses of a systematic airborne gamma radiation and total magnetic survey for the area identified as Marysvale, located in southwestern Utah, is presented in Volumes I-IV of this report. The airborne data gathered is reduced by ground computer facilities to yield profile plots of the equivalent uranium, thorium and potassium gamma radiation intensities, the ratios of these intensities, the total gamma radiation counting rate and the earth's residual magnetic field intensity. Profile plots of the aircraft's altitude above the earth's surface, the ambient temperature and pressure, and the magnetic field data measured by a base station magnetometer is presented also. An evaluation of the distribution of the radiometric data in terms of its established geochemical map units, which were derived via geochemical analysis methods, for the entire survey area has been prepared and is included. The determination of the geochemical units presented has been established principally from the analysis of the radiometric and magnetic contour maps and, more importantly, the multi-variate analysis map. A general description of the area, including descriptions of the various geologic and geochemical units, is included within the text. This volume contains the 5-variable residual magnetic and ancillary stacked profile data for the entire survey area
