Geochemistry and U–Pb Geochronology of Garnet From the Somerset and Arab Gold Deposits, Vumba Greenstone Belt, Northeastern Botswana: Implications for the Timing of Gold Mineralization

Resource Geology, Volume 75, Issue 1, January/December 2025.
A syn‐ to post‐peak amphibolite facies gold mineralization event has been identified in the Vumba Greenstone Belt (VGB) of northeastern Botswana. The garnet U–Pb dating yields three overlapping ages of sulfide‐bearing garnets: garnet 1 (2655 ± 58 Ma), garnet 2 (2680 ± 113 Ma) and garnet 3 (2679 ± 41 Ma).

Quantifying the effects of different hydrocarbon charging periods on reservoir quality: A case study of the Upper Wuerhe Formation, Junggar Basin, NW China

Energy Exploration & Exploitation
Mineral dissolution and precipitation is an important factor affecting pore genesis and hydrocarbon accumulation in sedimentary basins. Differential diagenetic processes at different hydrocarbon charging periods generally cause disparate effects on ...

Gold Mineralization Triggered by Contact Metamorphism at Mano Deposit in the South Kitakami Belt, Japan

Resource Geology, Volume 75, Issue 1, January/December 2025.
Genetic model of the Mano deposit. The magmatic intrusion metamorphosed the calcsilicate sedimentary rock to pyroxene hornfels. During the contact metamorphism, supercritical metamorphic fluid separated H2O, H2S and CO2 into the vapor phase, and the remaining hydrothermal fluid containing LMCEs melts transported Au to form Bi‐Te metal alloy‐enriched ...

Deformation and Failure Characteristics of Uniaxial Compression Prestressed Red Sandstone Under Short‐Term Immersion Conditions

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
To study the impact of short‐term water immersion on rock structures during water inrush or storage, a series of water immersion uniaxial compression (UC) tests were conducted on prestressed red sandstone. The effects of prestress levels (0, 0.5σc0, 0.7σc0, and 0.8σc0; σc0 is the uniaxial compressive strength) and immersion heights (0, 1/8H, 1/4H, 1/2H,

The Origin of the Matter Matters: The Influence of Terrestrial Inputs on Coastal Benthic Microeukaryote Communities Revealed by eDNA

Environmental DNA, Volume 6, Issue 6, November–December 2024.
Changes in the matter origin are reflected in estuarine benthic microeukaryote diversity. Specific taxa are associated with different metal inputs, which are linked to the geological characteristics of watersheds. The study of New Caledonian ecosystems can lead to the development of marine bioindicators of metallic inputs from land.

Diagenetic differences controlled by sediment composition and their implications for reservoir quality in the deep-buried Permian Urho Formation, Fukang Sag, Junggar basin

Natural Gas Industry B
Deeply buried coarse clastic reservoirs of the Permian Upper Urho Formation in the Fukang Sag, Junggar Basin, exhibit pronounced reservoir-quality heterogeneity in pore systems and lithofacies architecture.
