J. H. Bell and B. B. Bowen Fracture-focused fluid flow in an acid and redox-influenced system: diagenetic controls on cement mineralogy and geomorphology in the Navajo Sandstone Geofluids 14
A morphologically distinct butte located in Southern Utah, in Grand Staircase-Escalante National Monument, has experienced a history of fluid–sediment interactions resulting in anomalous diagenetic iron sulfate (jarosite). We propose that the jarosite cement could have formed from fracture-directed acidic fluids resulting from weathering of proximal, unidentified sulfides, or H2S associated with deep source beds, and along with other secondary cements created an erosion-resistant cap that helped control the butte's geomorphic evolution.
