Early diagenetic vivianite [Fe-3(PO4)(2) center dot 8H(2)O] in a contaminated freshwater sediment and insights into zinc uptake: a mu-EXAFS, mu-XANES and Raman study [PDF]

, 2008
The sediments in the Salford Quays, a heavily-modified urban water body, contain high levels of organic matter, Fe, Zn and nutrients as a result of past contaminant inputs.

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: a synthesis and review [PDF]

, 1996
The stable oxygen isotope composition (d¹⁸O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (d¹³C) reflects the source of CO2 for ...

Controls of depositional facies and diagenetic alterations on reservoir quality of the Fahliyan Formation in the Central Zagros area [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Fahliyan Formation is a member of the Khami Group with Neocomian–Barremian age. In two surface sections in the Izeh Zone and two wells of the southern Dezful Embayment, it includes 12 microfacies deposited on four facies belts as tidal flat, inner ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter [PDF]

, 2017
Sulfate reduction plays an important role in altering dissolved organic matter (DOM) in estuarine and coastal sediments, although its role in the production of optically active chromophoric DOM (CDOM) and a subset of fluorescent DOM (FDOM) has not been ...

Bone diagenesis in a Mycenaean secondary burial (Kastrouli, Greece)

Archaeological and Anthropological Sciences, 2019
This paper presents the characteristics of bone diagenesis in a secondary commingled Mycenaean burial in Kastrouli (Phocis, Greece) through the histological (light microscopy), physical (FTIR-ATR), and biochemical (collagen) analysis of seventeen human ...

Kinetic models of diagenesis in disturbed sediments. Part 2. Nitrogen diagenesis [PDF]

Limnology and Oceanography, 1977
A two‐layer mass transfer model developed to describe the vertical silica profile in the sediments of a muddy zone of the North Sea along the Belgian coast is applied to the description of the microbiological processes involved in nitrogen diagenesis in the same sediments.
