Cutler Group Alluvial, Eolian, and Marine Deposystems: Permian Facies Relations and Climatic Variability in the Paradox Basin

Abstract

Stratigraphic complexity, sedimentologic features, and regional facies changes within the Permian System in the Paradox Basin record a succession of complex but similar depositional systems. Each system ranges from alluvial fans proximal to source areas to the northeast in the ancestral Uncompahgre Highlands, westward through eolian ergs, sabkhas, and fluvial-floodplain units in medial settings, to estuarine and tidal or sabkha to fully marine systems in distal settings. This paper provides: (1) an overview of rocks of the Permian System, including discussions on the regional depositional setting, and tectonic and paleoclimatic controls on sedimentary cyclicity; and (2) photographic examples of typical exposures of the strata with and around the basin.
