Unraveling the risk of dredging on river bars for mineral sand mining: an engineering geological approach by Md. Shohel Rana, A.T.M. Shakhawat Hossain, Md. Fuad Hasan, Md. Aminur Rahman, Pradip Kumar Biswas, Mohammad Nazim Zaman

“…The study also identifies the risk of localized slumping and soil instability, which exacerbated by micaceous and quartz-rich sands. The CBR results further classify the subgrade as weak to medium-strong, indicating risks of slumping, erosion, and instability. …”

Depth variations as effective indicators for strength variation of Najran granites, Najran region, Saudi Arabia by Ahmed Abd El Aal, Yahya Al Zamana, Turki Dunquwah, Omar Alsalmi, Jabir Hussain, Javed Iqbal, Moustafa Abdulrahim Mohamedsalih, Ahmed E. Radwan, Hezam Al-Awah

“…Analyses of XRF data also considered the mechanical reasons for the strength with burial depth effects; findings suggested a direct relationship between burial depths and UCS values and inverse relationship with quartz content. For a better knowledge of the granites throughout the region, it is advised to carry out comparative studies on other granites in Saudi Arabia and create a comprehension model using numerical simulation.…”

Mineralogy and geochemistry of shale from Shanxi Formation, Southern North China Basin: Implication for organic matter accumulation by Qian Chen, Pei Li, Xiaoliang Wei, Changsheng Chen, Wei Dang, Haikuan Nie, Jinchuan Zhang

“…The Shanxi Shale is primarily composed of clay minerals (34.24 %–75.20 %) and quartz (23.80%–46.39 %), with a notably low carbonate content (<5 %). (2) Illite in the lower sections of the Shanxi Shale is likely sourced from detrital input rather than chemical conversion, while the dissolution of potassium feldspar may account for the elevated kaolinite content. …”

A sedimentological oxymoron: highly evolved glauconite of earliest diagenetic origin by Tribovillard, Nicolas, Bout-Roumazeilles, Viviane, Guillot, François, Baudin, François, Deconinck, Jean-François, Abraham, Romain, Ventalon, Sandra

“…Contrasted grain-size distribution patterns of glauconite and quartz grain populations (isolated after acid digestion and magnetic separation) evidenced that glauconite formed after sediment deposition. …”

The contrasting origins of glauconite in the shallow marine environment highlight this mineral as a marker of paleoenvironmental conditions by Tribovillard, Nicolas, Bout-Roumazeilles, Viviane, Abraham, Romain, Ventalon, Sandra, Delattre, Marion, Baudin, François

“…Being chemically and physically resistant, glauconite is a mineral that is often reworked, like quartz grains. This is frequently the case of the Jurassic deposits of the Boulonnais, where glauconite, almost ubiquitous, either in traces or in significant proportions of the sediments, presents a grain size sorting attesting to its transport and reworking. …”

Hydrogen and hydrogen sulphide in volcanic gases: abundance, processes, and atmospheric fluxes by Aiuppa, Alessandro, Moussallam, Yves

“…The high H$_{2}$ concentrations (and low H$_{2}$S/SO$_{2}$ compositions, of ${\sim }$0.1 on average) in high-temperature (${>}$1000 °C) magmatic gases are overall consistent with those predicted thermodynamically assuming external redox buffering operated by the coexisting silicate melt, at oxygen fugacities ranging from ${\Delta }$FMQ $-$1 to 0 (non-arc volcanoes) to ${\Delta }$FMQ 0 to ${+}$2 (arc volcanoes) (where ${\Delta }$FMQ is oxygen fugacity expresses as a log unit difference relative to the Fayalite–Magnetite–Quartz oxygen fugacity buffer). Lower temperature (${<}$1000 °C) volcanic gases exhibit more oxidizing redox conditions (typically above the Nickel–Nickel Oxide buffer) that are caused by a combination of (i) gas re-equilibration during closed-system (gas-phase only) adiabatic cooling in a gas-buffered system, and (ii) heterogenous (gas–mineral) reactions. …”
