Remote sensing assessment of rapidly changing lake areas in semi-arid closed basins : modern playa lake response to meteorological variability and implications for pluvial Lake Palomas Holocene highstands
Closed basin lakes provide important data on paleo- and modern environmental conditions because of their sensitivity to climate variability, particularly variations in precipitation. In arid and semi-arid regions throughout the world, playas play an important role in biological communities, …

Seismic site characterization via joint modeling of horizontal-to-vertical spectral ratios and surface wave dispersion : developing and validating a geophysical tool for deciphering Quaternary stratigraphic architecture of the Monahans dune field, West Texas.
… well as buried clay, carbonate-rich soils, and playa lake deposits. The complex and discontinuous stratigraphy of Monahans is difficult to capture without extensive borehole investigation. Shallow seismic techniques using Horizontal-to-Vertical Spectral Ratios (HVSR) and surface wave dispersion …

Depositional Environments of Siliceous Laminites in the Laney Member of the Green River Formation, Sublette County, Wyoming
… near-shore, oxygenated saline - alkaline lake environment, as inferred from (1) the association of stromatolites , mud-cracked dolomicrites and ostracodal micrite, (2) fossil occurrences of Knightia (Herring-type fish) and Equisetum (horsetail), Astephus (catfish), Amyzon (sucker ) and (3) …

Depositional and Diagenetic History of the Permian Unayzah A Reservoir, South Haradh, Saudi Arabia with Implications for Deep Gas Exploration and Development
… dune, sand sheet, interdune and ephemeral (playa) lake facies. Diagenetic products in Unayzah A developed during a continuum of eogenetic and mesogenetic reactions. Early or eogenetic cements are dominated by clay rims that formed at temperatures below 70oC. Oil migration along stylolites …

Stratigraphic and structural evolution of the early Diligencia Basin, Orocopia Mountains, Southeastern California
… and that interfingered with deposits of a playa lake complex that formed in the basin interior. The age of these deposits, basin geometry, and the style of sedimentation are very reminiscent of half-graben basins known from the Colorado River Extensional Corridor of the Basin and Range. …

Characterization of an Upper Permian tight aas reservoir : a multidisciplinary, multiscale analysis from the Rotliegend, Northern Germany
… Upper Rotliegend II included perennial saline lakes, coastal parallel sand belts comprising wet, damp and dry sandflats and aeolian dunes with interdune deposits. Polygonal patterns at different scales were observed on seismic horizon slices in the reservoir intervals and the overlying …

Plio-Pleistocene Drainage Evolution of The Vera Basin, SE Spain
… fan system intercalated with an evaporitic playa lake. A third drainage system in the northwest of the basin (Salmeron) developed within a topographic low between the two fan systems. An increase in structural activity towards the end of the Salmeron Formation was characterised by a basin …

At the water's edge: an archaeological investigation of playa occupation in the Central Plains
Playa research on the American Great Plains has considerable potential to shed light on ancient hunter-gatherer lifeways and subsistence. These lacustrine environments provide a predictable water source and are ecological hubs for many species of mammals, waterfowl, and vegetation. The availability …
