Gravity studies in Utah

Since 1955, the Department of Geophysics of the University of Utah has made gravity surveys throughout Utah in a continuing program to compile a gravity map of the entire state [Cook and Berg, 1958]. The field wrork and compilation and interpretation of data have been chiefly done by graduate students and faculty of the Department of Geophysics incident to thesis and staff research. Financial support for the surveys has been provided by various federal, state, and private agencies and organizations, including the National Science Foundation, Utah Engineering Experiment Sta‐G13649. tion of the University of Utah, University Research Fund of the University of Utah, and several petroleum and mining companies. The techniques of collection and reduction of the gravity data are given by Cook and Berg [1961] and Cook et al. [1964] and will not be repeated here. The areas of published gravity coveragein Utah are shown in Figure 1 and are numerically keyed to the References, Part 2. The areas of unpublished gravity coverage by the University of Utah or of gravity surveys in progress are listed in Table 1. The areas of published and unpublished gravity coverage in Utah by the U. S. Geological Survey [Case, 1965] are also included in Figure 1 and Table 1. All unpublished gravity data of the University of Utah, including theses, are being prepared for publication, ordinarily in approximately 1° X 1° (or fractions or multiples thereof) quadrangle maps in which the Bouguer gravity anomaly contours are superimposed on the generalized geology of the surveyed area. The final publication of the gravity maps of several areas lias been deferred, pending the publication of the new geologic maps of the state of Utah [Stokes and Madsen, 1961; Stokes, 1963; Hintze, 1963; Hintze and Stokes, 1964]. These geological maps of Utah have recently been completed, and the gravity maps will be published as soon as possible.
