Stratigraphy and paleogeography of the Ediacaran Doushantuo Formation (ca. 635-551Ma) in South China
TL;DR: The Doushantuo Formation (ca. 635-551 ǫ Ma) is one of the most intensively investigated Ediacaran units in the world.

Evolution of Cretaceous to Eocene alluvial and carbonate platform sequences in central and south Jordan.
John H. Powell,Basem K. Moh’d +1 more
TL;DR: In this article, the authors describe a sequence stratigraphic and lithofacies scheme that can be correlated with the evolution sedimentation on the Arabian and Levant plates, in which three major sequence boundaries are described (Kurnub, Ajlun and Belqa).
Journal ArticleDOI
Compositional controls on early diagenetic pathways in fine-grained sedimentary rocks: Implications for predicting unconventional reservoir attributes of mudstones
TL;DR: In this article, the Kimmeridge Clay and Monterey Formation mudstones were investigated to determine how varying starting compositions of the mudstones influence diagenesis, and the results showed that the resulting changes in mud composition at deposition significantly influence subsequent diagenisation.

Sedimentary and Igneous Phosphate Deposits: Formation and Exploration: An Invited Paper
Peir K. Pufahl,Lee A. Groat +1 more
TL;DR: In the early Neoproterozoic, carbonatite-alkaline rock complexes commonly possess a concentric, zonal structure thought to reflect caldera volcanism, which is a primary exploration target in upwelling-related phosphorite.

The role of microbes in the formation of modern and ancient phosphatic mineral deposits.
Chris H. Crosby,Jake V. Bailey +1 more
TL;DR: It is demonstrated that polyphosphate utilization by sulfide-oxidizing bacteria results in the rapid precipitation of apatite – providing at least a partial mechanism to explain the close spatial correlation between accumulations of sulfides and phosphorites.

On the Isotopic Chemistry of Carbonates and a Paleotemperature Scale
TL;DR: In this paper, the temperature variation of the fractionation of oxygen in exchange reactions between dissolved carbonate and water and between calcite and water was calculated on theoretical grounds, and checked experimentally.

Early oxidation of organic matter in pelagic sediments of the eastern equatorial Atlantic: suboxic diagenesis
Philip N. Froelich,Gary P. Klinkhammer,Michael L. Bender,Nile A. Luedtke,G.R. Heath,Doug Cullen,Paul Dauphin,Doug Hammond,Blayne Hartman,Val Maynard +9 more
TL;DR: Pore water profiles of total CO 2, pH, PO 3−4, NO − 3 plus NO − 2, SO 2− 4, S 2−, Fe 2+ and Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic under waters of moderate to high productivity as mentioned in this paper.

Sediment Gravity Flows: II Depositional Models with Special Reference to the Deposits of High-Density Turbidity Currents
TL;DR: In this article, sediment deposition from individual sediment flows commonly involves more than one of these mechanisms acting either serially as the flow evolves or simultaneously on different grain populations, and the effects of hindered settling, dispersive pressure, and matrix buoyant lift are con entration dependent.
Journal ArticleDOI
Isotopic evidence for source of diagenetic carbonates formed during burial of organic-rich sediments
TL;DR: In this article, the relative dominance of different burial diagenesis processes within specific depth intervals is given by the isotopic composition of incorporated oxygen which is temperature dependent (1) 0 to −2‰, (2) −1.5 to −5'
