Journal ArticleDOI
Reduction of water with zinc for hydrogen isotope analysis
TL;DR: In this article, a 1-10 mg portion of water is reduced with Zn metal in a sealed tube at 450 /sup 0/C to prepare hydrogen for isotopic analysis.
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'
Journal ArticleDOI
Reduction of Fe(III) in sediments by sulphate-reducing bacteria
TL;DR: Geochemical and microbiological studies suggest that contemporary formation of siderite concretions in a salt-marsh sediment results from the activity of sulphate-reducing bacteria, which may be an important and previously unrecognized agent for Fe(III) reduction in aquatic sediments and ground waters.
Journal ArticleDOI
Geochemistry of diagenetic non-silicate minerals: kinetic considerations
TL;DR: The early stages of burial diagenesis involve the reactions of various oxidizing agents with organic matter, which is the only reducing agent buried with the sediment as discussed by the authors, and thermodynamic principles indicate that, inter alia, manganese, iron and sulphate should each be consumed successively to give rise to a clearly characterized vertical zonation.
Journal ArticleDOI
Pore water evolution during sediment burial from isotopic and mineral chemistry of calcite, dolomite and siderite concretions
TL;DR: In the Central Pennine Region of England, three different types of concretions (calcite/pyrite, dolomite, pyrite and siderite) occurring spatially quite close together in the central Pennine region of England vary widely in carbon isotope composition (+10.35% >δ13C > −21.49% as mentioned in this paper.
