Deep Underground Science and Engineering, EarlyView.The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.

Solidification pipes: from solder pots to igneous rocks [PDF]
arXiv, 1999 When a substance that shrinks in volume as it solidifies (for example, lead) is melted in a container and then cooled, a deep hole is often found in the center after resolidification. We use a simple model to describe the shape of the pipe and compare it with experimental results.

Potential of basalt dust to improve soil fertility and crop nutrition
Journal of Agriculture and Food Research, 2022 The search for higher yields, lower production costs, and increased sustainability in agriculture implies optimizing crop nutritional management. In this sense, basalt dust has shown potential to improve soil fertility and crop nutrition.

Energy Science &Engineering, EarlyView.Experimental evaluation of water phase trap damage in tight sandstone reservoirs ABSTRACT The C‐S reservoir in the YQ district of Ordos basin, China, is located at a relatively shallow depth (240–720 m), with an original pressure coefficient of approximately 0.85 for the oil layer. Calculations indicate that the initial pressure of the oil layer ranges

Prediction of uniaxial compressive strength of rock based on lithology using stacking models
Rock Mechanics Bulletin, 2023 Uniaxial compressive strength (UCS) of rock is an essential parameter in geotechnical engineering. Point load strength (PLS), P-wave velocity, and Schmidt hammer rebound number (SH) are more easily obtained than UCS and are extensively applied for the ...

Energy Science &Engineering, EarlyView.ABSTRACT The multi‐field coupling relationship and temperature evolution mechanism of gas‐containing coal in areas affected by geological structures were investigated, focusing specifically on the engineering aspects of a reverse fault in the No. 3 coal seam at the Xinjing Coal Mine. An analysis was conducted to examine the thermal‐fluid‐solid coupling

Applied Vegetation Science, Volume 25, Issue 4, October/December 2022., 2022 We estimated the future distribution of alpine and subalpine vegetation types under climate change in the Taisetsu Mountains, Daisetsuzan National Park, Hokkaido (northern Japan). Under the RCP2.6 scenario, habitats suitable for snowbeds and alpine heathland/fellfield drastically decreased overall.
