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.

One Billion Years of Stability in the North American Midcontinent Following Two‐Stage Grenvillian Structural Inversion

Tectonics, Volume 43, Issue 9, September 2024.
Abstract The North American craton interior preserves a >1 Ga history of near surface processes that inform ongoing debates regarding timing and drivers of continental‐scale deformation and erosion associated with far‐field orogenesis. We tested various models of structural inversion on a major segment of the Midcontinent Rift along the Douglas Fault ...

Frictional Properties of Feldspar‐Chlorite Gouges and Implications for Fault Reactivation in Hydrothermal Systems

Earth and Space Science, Volume 11, Issue 7, July 2024.
Abstract As a particularly common mineral in granites, the presence of feldspar and feldspar‐chlorite gouges at hydrothermal conditions has important implications in fault strength and reactivation. We present laboratory observations of frictional strength and stability of feldspar (K‐feldspar and albite) and feldspar‐chlorite gouges under conditions ...

The Geochemical and Mineralogical Signature of Glaciovolcanism Near Þórisjökull, Iceland, and Its Implications for Glaciovolcanism on Mars

Journal of Geophysical Research: Planets, Volume 129, Issue 7, July 2024.
Abstract Candidate glaciovolcanic landforms have been identified across Mars, suggesting that volcano‐ice interactions may have been relatively widespread in areas that once contained extensive surface and near‐surface ice deposits. To better constrain the detection of glaciovolcanism in Mars' geological record, this study has investigated and ...

Experimental investigation of kinetics and rheology during diagenesis [PDF]

, 1998
Two processes of enormous economic consequence occur within the upper to middle crust: the formation, migration, entrapment, and degradation of hydrocarbons, and hazardous seismicity. Substantial scientific evidence suggests that both these processes are

A Quantitative Provenance Analysis (QPA) Approach to Quantify Controls on Sediment Generation and Sediment Flux in the Upper Reaches of the Magdalena River (Colombia): 2. Lithological Control on Contribution to Silt‐ to Clay‐Sized Fractions

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 5, May 2024.
Abstract The composition of 27 fluvial silt and clay sediments was used in this study to identify and quantify the processes in the upper valley of the Magdalena river in South Colombia. The combination of seismic activity, intense precipitation, and landsliding resulted in limited chemical weathering and a very efficient transfer of weathered products
