The sulfur cycle influences the respiration of sedimentary organic matter, the oxidation state of the atmosphere and oceans, and the composition of seawater. However, the factors governing the major sulfur fluxes between seawater and sedimentary reservoirs remain incompletely understood. Using macrostratigraphic data, we quantified sulfate evaporite burial fluxes through Phanerozoic time. Appro...

Abstract The Paleoproterozoic Mârmorilik Formation in the Karrat basin of West Greenland hosts Black Angel Zn–Pb deposit. Chlorine-rich scapolite, zones with vuggy porosity and quartz nodules ore-bearing marble are herein interpreted to represent metamorphosed, vanished, replaced evaporites, respectively. Mineralization is closely associated anhydrite δ 34 S values (5.2–12.6‰) broadly comparabl...

Fluid systems in inverted rifted margins are challenging to interpret because fractures formed before compression were often reactivated acting as fluid pathways new ones formed. Deciphering the fracture and flow history such complex settings has key implications for prediction of distribution mineral resources. As an example, we reconstruct evolution a portion Pyrenean rift, Upper Pedraforca t...

The structure of the southwestern branch Alpine orogen is affected by extensive Late Triassic evaporites. These evaporites have been involved in polyphased salt tectonics since early Liassic, coeval with Tethyan rifting, and are décollement level for thrusts external parts during orogeny. role this arc re-evaluated order to determine relative importance deformation related motion respect main c...

Fluids such as 4He, H2, CO2 and hydrocarbons accumulate within Earth's crust. Crustal reservoirs also have potential to store anthropogenic waste (e.g., CO2, spent nuclear fuel). Understanding fluid migration how this is impacted by basin stratigraphy evolution key exploiting accumulations identifying viable storage sites. Noble gases are powerful tracers of chemical evolution, they inert only ...

SUMMARY The axial region of the Central Red Sea has been shown to be floored by oceanic crust, but this leaves low amplitudes off-axis magnetic anomalies explained. Furthermore, if seafloor spreading occurred in late Miocene, it is unclear how that as widespread evaporites were being deposited then and may have covered centre. In study, we derive crustal magnetization for a constant-thickness s...

The Alpine Haselgebirge Formation represents an Upper Permian to Lower Triassic evaporitic rift succession of the Northern Calcareous Alps (Eastern Alps). Although the rocksalt body deposits are highly tectonised, consisting mainly of protocataclasites and mylonites of halite and mudrock, the early diagenetic history can be established from non-tectonised mudrock bodies: Cm-sized euhedral halit...

We report a hitherto unknown occurrence of ancient Neoproterozoic evaporite deposits from an allochthonous terrane in the Pan-African Gariep belt in Namibia. Low contents of Rb, Cs, Ba, Zr, Hf, Th, and U, flat chondrite-normalised rare earth element (REE) patterns, Sr/Sr ratios as low as 0.7075, Na–Cl–Br systematics of fluid inclusion leachates, and high dB values for stratiform tourmalinites, ...
