Airborne Geophysical Survey of the Oquirrh Mountains, Utah

In 1994, Kennecott Utah Copper Corporation (now Rio Tinto Kennecott Corporation) commissioned DIGHEM Inc. to collect an airborne geophysical survey over the entirety of the Oquirrh Mountains. The Oquirrh Mountains airborne geophysical survey contains electromagnetic (EM), aeromagnetic, aeroradiometric, and very low frequency (VLF) data over the most significant mineral-producing area in Utah and remains the most complete geophysical dataset over the mountain range to date. The survey represents a dataset that would be unfeasible to collect under modern airspace considerations. The data in this report was contributed through a joint agreement by Rio Tinto Kennecott Corporation and Rio Tinto Exploration with the Utah Geological Survey to ensure this valuable dataset can be used for continuing geologic interpretation of the Oquirrh Mountains for topics that are important for mineral exploration, such as mineral deposit formation, structural evolution, and magmatic emplacement.
