Rock‐buffered versus fluid‐buffered geochemistry of structurally controlled, hydrothermal dolomite: Insights from the Sichuan Basin, China

Sedimentology, EarlyView.
ABSTRACT Structurally controlled hydrothermal dolomitization, commonly driven by high‐pressure, high‐temperature fluid–rock reactions, offers insights into the tectonic evolution of sedimentary basins and the geochemical composition of their diagenetic fluids.

Sedimentological characterisation is a necessary prerequisite for interpretation of stable carbon isotope ratios of bulk sediment from reefal settings

Sedimentology, EarlyView.
ABSTRACT For most of Earth history, carbonate sediments deposited in shallow marine settings are the only remaining archive of changing biogeochemical cycles. All deep‐sea sediments older than >200 Ma have been subducted and are therefore lost from the record. Stable carbon isotope (δ13C) values of shallow marine carbonates are available for older time

Aligned hydrothermal fluid‐flow pathways in Middle Permian near‐shore marine sediments beneath a basaltic lava flow

Sedimentology, EarlyView.
ABSTRACT Tubular and curviplanar structures, outlined by the occurrence of haematite/goethite, chlorite, quartz and albite, are developed in the Middle Permian Broughton Formation in the southern Sydney Basin, New South Wales, Australia. These structures are interpreted as fluid‐flow pathways resulting from the ejection of heated pore fluids as a thick

Kuroko Deposits of NE Japan: The Product of High‐Temperature, Shallow Felsic Volcanism in a Deepening Continental Rift

Terra Nova, EarlyView.
ABSTRACT The Hokuroku district of NE Japan hosts the type locality for Kuroko volcanic‐hosted massive sulphide (VHMS) deposits, which are the product of seafloor hydrothermal venting in a continental rift during the opening of the Sea of Japan in the Miocene.
