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 ...

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 ...

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
