Hot Fan or Cold Outwash? Hypothesized Proglacial Deposition in the Upper Paleozoic Cutler Formation, Western Tropical Pangea

Untitled

“…That is, the uplift and surrounding regions underwent subsidence together. The thickness of the proximally exposed Cutler Formation, 965 m as indicated by the sequential measured sections of the Cutler Formation in its most proximal location against the uplift (Soreghan et al, 2009a), provides a minimum amount of subsidence on the Uncompahgre highland, and closely approximates the 970 m of preserved paleorelief within Unaweep Canyon. The inference of subsidence of the Uncompahgre uplift is also consistent with Cater's (1970) observation that well data near the Gateway area show > 2000 m of Cutler strata on top of Precambrian basement, and thus subsidence of the upthrown block.…”

Clastic detritus eroded from the highland during Carboniferous-Permian tectonism accumulated in the adjacent Paradox basin to form the Cutler Formation (Wengerd, 1962;Mallory, 1972;Campbell, 1980;Mack and Rasmussen, 1984;Condon, 1997;Dubiel et al, 2009;Soreghan et al, 2009a).…”

Evolution of fluvial systems in salt-walled mini-basins: A review and new insights

“…9b;Werner, 1974;Mack and Rasmussen, 1984;Cain and Mountney, 2009;Venus, 2013). The prevailing climate at this time was dominantly semi-arid (Werner, 1974;Cain and Mountney, 2009), though with evidence for 21 more humid episodes at times Mountney, 2009, 2011;Soreghan et al, 2009). Evidence for these climatic variations are recorded in part by the progradation and retrogradation of the Organ Rock Formation, a ~100 m-thick wedge of alluvial strata, which is the lateral equivalent of the Undivided Cutler Group and which interacts with an aeolian dune field in the distal part of the Paradox Basin, beyond the margin of the Salt Anticline Region (Cain and Mountney, 2009).…”
