Red beds geology

Therefore, the deep red-bed in the study area are expected to become potential sites of geological carbon sequestration. 6. Conclusions. Contrasted with red-bed bleaching in the outcrop easy to be found and widely reported, deep red-bed bleaching is seriously neglected due to its concealment, especially in petroliferous basins.

Red beds provide further evidence for atmospheric redox change. They derive from wind-blown dust or river-transported grains coated with red-colored hematite (Fe 2 O 3). Before ∼2.3 Ga, red beds are very rare, whereas afterwards red beds are ubiquitous.

A fundamental problem with this hypothesis is the relative scarcity of recent red colored alluvium, and Van Houten (1961) developed the idea to include the in situ (early diagenetic) reddening of the sediment by the dehydration of brown or drab colored ferric hydroxides.

The Cretaceous oceanic red bed (CORB) is a newly opened window on global oceanic and climate changes during the Cretaceous greenhouse world. As a result of the International Geoscience Programmes 463, 494 and 555 (2002–2010), CORBs have been documented in many places by numerous publications.Jan 1, 2009 · Cretaceous oceanic red beds (CORBs) are mainly pelagic red shales, marls, or fine-grained limestones. These facies have been the subject of two closely related International Geosciences Programs GCP 463 and 494. They are a significant facies of deep-water pelagic deposits and pelagic-hemipelagic sedimentary systems. Red beds of Cala Viola, Sardinia are identified as paleosols and used to reconstruct Late Permian paleoclimatic conditions. Reconstruction of paleoenvironmental conditions based on the paleosols of the Cala Viola indicates warm, humid conditions with no evidence of dry conditions, as in a desert, or of extreme seasonality as in a monsoon.In the Maremane Dome, the red beds preserve pisolitic hematite laterites, which indicate a highly oxygenated atmosphere and suggest hot and humid climatic conditions. The Mapedi and Gamagara Formations are undated east of the Blackridge thrust but were thought to be lithological correlatives of the ≥1.91 Ga Mapedi red bed sequence … ….
