Red beds geology

The evidence includes field, petro-graphic, and chemical data collected from studies of two stratigraphic sequences that contain red beds: (1) Recent, Pleistocene, and Pliocene deposits in the Sonoran desert of northeastern Baja California, Mexico, and (2) late Paleozoic deposits in Colorado. The sequence in the Sonoran desert contains examples ....

In particular, there is a lack of consensus about the impact of hydrothermal activity on Cretaceous lacustrine red beds. For this study, we used geological and geochemical analyses to describe sediment characteristics and the unusual content of elements preserved in the Cretaceous red beds of the North Yellow Sea Basin (NYSB).In particular, there is a lack of consensus about the impact of hydrothermal activity on Cretaceous lacustrine red beds.

Red beds are sediments and sedimentary rocks with hues ranging from 2.5YR to 5R. Reddish pigmentation of these deposits is present in both surface exposures and subsurface well cores. Strata containing red beds commonly exhibit color mottling and may include layers that are not red.Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain thin beds of conglomerate, marl, limestone, or some combination of these sedimentary rocks.
