Summary

Samples of vein-type magmatic-steam alunite were collected over several field seasons from five mines and prospects (L&N, Mt. Edna, Christmas, upper Mineral Products, and Close In) in the Alunite Ridge and Deer Trail Mountain area, Marysvale, Utah, as well as a sample from the Deer Trail mine workings from which sericite was separated. The magmatic-steam alunite and sericite were analyzed by the 40Ar/39Ar method to constrain the timing and duration of magmatic activity associated with the intrusion of two porphyry stocks beneath Alunite Ridge and Deer Trail Mountain. In addition, a sample of a highly altered rhyolitic quartz porphyry dike was collected from the upper Mineral Products mine, from which zircons were separated and analyzed [...]

Purpose

The data were collected to constrain the timing and duration of intrusive activity, especially of magmatic hydrothermal activity associated with the emplacement of two (still concealed) porphyry stocks beneath Alunite Ridge and Deer Trail Mountain, Marysvale, Utah. Our approach may be useful in exploring for additional deeply concealed porphyry systems. This data release accompanies the planned publication "40Ar/39Ar Geochronology of Magmatic-Steam Alunite from Alunite Ridge and Deer Trail Mountain, Marysvale Volcanic Field, Utah: Timing and Duration of Miocene Hydrothermal Activity Associated with Concealed Intrusions". The manuscript describes the geology of the Alunite Ridge and Deer Trail Mountain area, constrains the timing and duration of Oligocene and Miocene intrusive and hydrothermal activity, and discusses implications for the framework geology of the Marysvale Volcanic Field and for exploration for concealed porphyry systems.
