A sedimentary record of the evolution of the global marine phosphorus cycle
Geobiology, 2022Phosphorus (P) is typically considered to be the ultimate limiting nutrient for Earth's biosphere on geologic timescales. As P is monoisotopic, its sedimentary enrichment can provide some insights into how the marine P cycle has changed through time.

The spectral evolution of sedimentary bed forms
Journal of Fluid Mechanics, 1974A potential-flow based analytical model is developed for the temporal development of the spectra of ripples and dunes generated on an initially flattened bed by an open-channel flow. The analysis predicts the occurrence of two distinct spectral peaks at small times; the physical origin of each is explained.

The Yangtze River delta, one of the largest tide-dominated deltas in the world, is a valuable archive for studying the land-sea interaction. Previous investigations have mainly focused on the Holocene Yangtze River delta initiation and the coastal ...

Evolution of Antarctic prospective sedimentary basins
Antarctic Science, 1989No less than 15–20 sedimentary basins are now known on the Antarctic continental landmass and surrounding continental shelves. Reconstruction of their tectonic and stratigraphic evolution is a specialized task. Owing to the polar position of the continent, the Pacific and Atlantic global geostructures are closely spaced there and the interplay between ...

Presalt reservoirs of the Santos Basin: Cyclicity, electrofacies, and tectonic-sedimentary evolution
Interpretation, 2019Presalt reservoirs of the Santos Basin accounted for more than 50% of Brazilian hydrocarbon production in the first two months of 2019. Its most important reservoirs are found in the Barra Velha Formation; thus understanding its genesis and geologic ...

Sandstones, Sedimentary Basins, and Continental Evolution
1972At some stage in the geological investigation of a sandstone, we need to place the formation in a larger perspective — to see it in relation to the basin fill as a whole and even to think about it in the longer view of geologic history and continental evolution. We need to go from a provincial to a cosmopolitan outlook.

Sedimentary sequences in the Subei Basin are complex and have been affected by interactions between the ocean and rivers since the Late Pliocene, including the Yellow River, Huaihe River, and the Yangtze River.

Basement and Sedimentary Recycling and Continental Evolution
The Journal of Geology, 1979The present day cumulative distribution of areas of continental basement age provinces (as defined by radiometric estimates) follows an exponential function. A similar distribution is displayed by the reserves of their associated economic deposits and by the thickness and areal distribution data for the overlying sediments.

New insights of the tectonic and sedimentary evolution of the Rio Grande Rise, South Atlantic Ocean
, 2019Oceanic plateaus, such as the Rio Grande Rise (RGR), comprise crucial pieces of information about the opening of the South Atlantic Ocean and the evolution of associated lithospheric plate margins. A detailed seismostratigraphic assessment of the volcano-
