Characterization of Contrasting Ore-Related Fluid Systems in the Paradox Basin
On 1 May 2024, Eytan Bos Orent, University of Arizona Ph.D. candidate, presented “Characterization of Contrasting Ore-Related Fluid Systems in the Paradox Basin” to the members and guests of the Arizona Geological Society. The 49-minute talk includes 8-minutes of Q&A.
ABSTRACT: A long history of fluid-rock interaction in the Paradox Basin has resulted in geologically diverse products caused by a range of fluid sources and drivers. The La Sal district is an example within the basin of a locus of fluid systems that formed U(-V) and Cu(-Ag) deposits, salt wall-proximal bleaching, hydrocarbon-induced pyritization, and carbonate-stable alteration. New mapping throughout La Sal Creek Canyon at multiple scales highlights the spatial relationships and superimposed fluid systems present in the district that are representative of those found in the Paradox Basin. Additional SEM, EMPA, whole rock, and LA-ICP-MS analyses help constrain the geochemical conditions under which fluids interacted with their environments and the absolute timing of key geologic events.
The U(-V) sandstone-hosted, tabular ore bodies found in the Jurassic Morrison Formation are localized in lithofacies typical of channel-fill deposits and are commonly bound both above and below by floodplain mudstones. Alteration associated with these deposits is characterized by a core with abundant quartz cements, concretions containing U and V ore minerals, and relatively few carbonate concretions relative to unmineralized host rocks. Lower Fe and higher OSMOW in authigenic carbonates in mineralized compared to mineralized sandstones provides evidence for distinct formation waters related to U(-V) mineralization. U-Pb geochronology of calcite intergrown with coffinite (U(SiO4) · nH2O) indicates an early Cretaceous age of mineralization that immediately follows the late Jurassic deposition of the host rocks but predates late Cretaceous thick foreland basin fill.
At least two Cu deposits in the Paradox Basin overlap in space with sandstone reservoirs containing obvious hydrocarbons adjacent to salt-related structures. Mapping at the Cashin Cu(-Ag) sandstone-hosted deposit shows several key relationships: concretionary carbonate cements are localized along the redox boundary that is presumed to be caused by hydrocarbon migration through porous sandstones, and Cu-sulfides are less abundant in units updip of the ore-controlling fault. Further evidence for the involvement of hydrocarbons in mineralization lies in the reconstructed water OSMOW that overlaps with modern oil and gas pumping well brines. The age of mineralization is constrained by radiometric dating of calcite and dolomite veins from around the basin that contain intergrown Cu- and Ag-sulfides. A cluster of ages in the middle to late Miocene raises questions concerning the timing of mineralization with respect to major tectonic events in the North American Cordillera.

    Why are you answering questions? Your reproduction of the canyon was good... But there's nothing on this Earth that is a million years old... The Grand Canyon is roughly 4500 years old. And you were right. It was carved out by a lake, but the sediments were laid down by the global flood. As you will find the same layers all over the world.

    Really fascinating talk. One question I have is, is it possible that the lake was generally relatively shallow, but there were a bunch of deep maar craters within it that formed low spots, and that those deep basins within the larger, mostly shallow lake were the primary habitat for those “Baikal” ostracods (and obviously the water was all connected, so you could then get dead ostracods deposited anywhere in it)? Or were the maars completely infilled by the time the lake existed at these levels? PS instead of switching between Google Earth and the geological map over and over, you can just add the geological map as an overlay with 50% transparency right in Google Earth.

    Did the main copper bearing intrusion somehow break off and “float up”. There are interesting examples of suddenly detached iceberg “shooters” in ice shelves at the toe of a floating glacial ice stream in Alaska n bays rising up 2-3x higher than expected. Thus we see a kind of “telescoping” event play out in minutes. The shooter then collapses under its own weight. I felt it was illustrative of what might happen when “rotation” occurs during relaxation of collision stress. I suggest the “keels” of mountain regions may be thus elevated. And so provide a “pathway” for dikes, fluid flow, breccia dikes etc. see the elevation trend along the alto Andes for comparison. Spikes from below?
