Upper Paleozoic depositional and diagenetic facies in a mature petroleum province (a field guide to the Guadalupe and Sacramento mountains)

Geologic framework for the national assessment of carbon dioxide storage resources: Permian and Palo Duro Basins and Bend Arch-Fort Worth Basin: Chapter K in <i>Geologic framework for the national assessment of carbon dioxide storage resources</i>

“…2). Preserved sedimentary rocks tend to be cyclic, reflecting the complex interaction of glacioeustastic events, regional tectonics, reciprocal sedimentation and sediment accumulation, facies migration, and diagenesis (Oriel and others, 1967;Scholle and Halley, 1980;Miall, 2008;Chen and others, 2013). The stratigraphic complexities of Permian strata is best demonstrated by the multitude of formal and informal stratigraphic units with multiple rank designations applied to the many rock-stratigraphic units occurring across the basin and discussed previously (Oriel and others, 1967;Ward and others, 1986;Dutton and others, 2004;Ruppel, 2008).…”

Evaluating Relationships Between Rock Strength And Longitudinal Stream Profile Morphometry In The Southern Guadalupe Mountains, Texas

“…The Southern Guadalupe Mountains offers an excellent opportunity to observe intercontinental marine shelf-margin stratigraphy. Canyons within these mountains outcrop the eastern edge of the Permian-aged Delaware Basin carbonate reef complexes that grade laterally into distinct back-reef, reef, fore-reef, and basin members with marine carbonate deposits, intermittent terrigenous sandstones, and evaporites ( Figure 2) (King, 1948;Scholle and Halley, 1980;Standen et al, 2009). Facies described here are part of a large carbonate reef system that rims the entire Delaware Basin (Figure 1b) (Standen et al, 2009).…”

“…During the Permian, large intertidal lagoons trapped highly saline marine waters that resulted in the deposition of thinly bedded, fine-grained, fossiliferous limestones (Scholle and Halley, 1980). Decreased tidal connection resulted in high magnesium concentrations that consequently led to the dolotimization of several carbonate units (King, 1948).…”

“…This transition zone is defined as the Capitan Reef Complex and includes the Carlsbad, Capitan, and Goat Seep Members. The Capitan and Goat Seep Members are widely fossiliferous lime-boundstones that are largely continuous with occasional "spur-and-groove" channel morphologies (Scholle and Halley, 1980). The Capitan Reef deposits display the largest faunal diversity consisting of calcareous sponges and blue-green algae as framework organisms, and encrusting organisms such as bryozoans, brachiopods, echinoderms, mollusks, ostracods, corals, and trilobites (Scholle and Halley, 1980).…”

“…King produced the first high-resolution geologic map of the Southern Guadalupe Mountains in 1948. Since then, several studies have explored the stratigraphic history and structural characteristics of this region (Scholle and Halley, 1980;Standen et al, 2009). They have found the region to be widely dominated by reef forming carbonates that act as both source and reservoir rock for petroleum and that display characteristics of complex syndepositional and extensional tectonics (King, 1948;Standen et al, 2009).…”
