Fluid Flow Origin and Evolution of the Callovian–Oxfordian Carbonate in the Fold‐Thrust Belt in the Right Bank of the Amu Darya River, Northeastern Turkmenistan

Geofluids, Volume 2025, Issue 1, 2025.
Complex fluid flow patterns can be triggered by tectonic forces generated during thrust emplacement along active margins in fold‐thrust belts and foreland basins. Isotope data (δ13C, δ18O, and 87Sr/86Sr), fluid inclusions, rare earth elements and yttrium (REEY), and U‐Pb dating of the calcite and saddle (Sd) dolomite veins are used to reconstruct the ...

Auriferous Fluid Evolution and the Role of Carbonaceous Matter in a Saddle‐Reef Gold Deposit: Dufferin Deposit, Meguma Terrane, Nova Scotia, Canada

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 12, December 2024.
Abstract The metaturbidite‐hosted, ∼380 Ma Dufferin gold deposit, Meguma terrane, northeastern Appalachian Orogen (Nova Scotia, Canada) is an orogenic gold deposit with mineralized saddle reef‐type quartz veins hosted by metasandstones and black slates in a tightly folded anticline. Together with native gold inclusions, genetically related hydrothermal

Tracing a Mantle Component in Both Paleo and Modern Fluids Along Seismogenic Faults of Southern Italy

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.
Abstract Aiming at understanding the source of the fluids that mineralizing within seismically active fault zones, we investigate the noble gas isotopes (i.e., helium (He), neon (Ne), and argon (Ar)) in the fluid inclusions (FIs) trapped in the calcite veins sampled along high‐angle fault zones of the Contursi hydrothermal basin, southern Italy.

The Life and Death of Hydrocarbon Traps in East Greenland: The Charge and Degradation Histories of Laplace Bjerg and the Mols Bjerge

Basin Research, Volume 36, Issue 6, November–December 2024.
The exhumed hydrocarbon traps of East Greenland received charge at maximum burial. Intrusive events resulted to the degradation of hydrocarbons to bitumen before remaining porosity was destroyed during uplift. Viable reservoirs may still exist at depth in adjacent offshore regions.

Depositional and Diagenetic Sulfates of Hogwallow Flats and Yori Pass, Jezero Crater: Evaluating Preservation Potential of Environmental Indicators and Possible Biosignatures From Past Martian Surface Waters and Groundwaters

Journal of Geophysical Research: Planets, Volume 129, Issue 2, February 2024.
Abstract The Mars 2020 Perseverance rover has examined and sampled sulfate‐rich clastic rocks from the Hogwallow Flats member at Hawksbill Gap and the Yori Pass member at Cape Nukshak. Both strata are located on the Jezero crater western fan front, are lithologically and stratigraphically similar, and have been assigned to the Shenandoah formation.

Joint application of fluid inclusion and clumped isotope (∆47) thermometry unravels the complexity of thermal and fluid‐flow history reconstruction in sedimentary basins—Upper Triassic Chaunoy Formation reservoirs (Paris Basin)

Basin Research, Volume 36, Issue 1, January–February 2024.
Precipitation timing and δ18Ofluid for the studied diagenetic carbonates obtained from different temperature datasets (fluid inclusions, ∆47). Abstract We investigated calcites and dolomites precipitated during burial diagenesis of the Upper Triassic (Norian) continental siliciclastics from sub‐surface reservoirs of the northern Paris Basin (Chaunoy ...

Multistage Gold‐Polymetallic Mineralization in the Bou Azzer District, Anti‐Atlas, Morocco: Insights from Ore Microscopic, Geochemical, and Fluid Inclusion Studies

Geofluids, Volume 2024, Issue 1, 2024.
The Bou Azzer polymetallic Co‐Ni‐As±Au±Ag veins in the Central Anti‐Atlas (Morocco) are significant sulfide ores hosted by Neoproterozoic ophiolites and are associated with felsic intrusive and subvolcanic phases. We report new mineralogical and fluid inclusion data to better understand mineralization’s formation processes and fluid evolution which are

The source of ore fluids in the Bafq district iron oxide-apatite deposits, Central Iran: a fluid inclusion approach

Journal of Economic Geology
The Bafq metallogenic district in the Kashmar-Kerman zone, or Posht-Badam block, in the Central Iran structural zone, hosts large iron oxide-apatite deposits hosted in Early Cambrian volcanic, subvolcanic, and sedimentary rocks, as well as in Precambrian

FLUID INCLUSION PETROGRAPHY AND MICROTHERMOMETRY ANALYSIS OF QUARTZITES OF GHATTIHOSAHALLI SCHIST BELT, DHARWAR CRATON, KARNATAKA, INDIA

Abstract Fluid inclusions both in quartz of fuchsite quartzite and quartzite rocks from the Ghattihosahalli Schist Belt area were examined with microthermometric methods. The study focuses on analysis of primary and secondary fluid inclusions present in quartz hosted in the quartzites to explore the stress and temperature conditions at the time of ...
