Failure Mechanism of Anti-Dip Layered Soft Rock Slope under Rainfall and Excavation Conditions
Sustainability, 2023 The phenomenon of toppling deformation and failure is common in slopes with anti-dip structures, especially in soft metamorphic rock slopes. This paper aims to explore the instability mechanism of anti-dip layered soft metamorphic rock landslides. Taking

The spread of non‐native species
Biological Reviews, EarlyView.ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Hydrogen adsorption characteristics of coal rock and its geological significance
Meitan xuebaoHydrogen, as an important clean energy source that can be used as an alternative to fossil energy, can reduce global greenhouse gas emissions. However, the large-scale hydrogen industry requires large reservoirs to store hydrogen, and the use of ...

Petrographic Evidences for the Origin of Iron in IOCG IronDeposits of Kuh-E-Faryadoon and Kouli-Kosh, Southeast Central Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2013 Kuh-E-Faryadoon and Kouli Kosh iron deposits are hosted by regional metamorphic rocks of Sanandaj-Sirjan zone around Deh-Bid area. Plugs and domes of acid rocks protrude these metamorphic rocks.

Biological Reviews, EarlyView.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Interpretation of zircon coronae textures from metapelitic granulites of the Ivrea–Verbano Zone, northern Italy: two-stage decomposition of Fe–Ti oxides [PDF]
Solid Earth, 2017 In this study, we report the occurrence of zircon coronae textures in metapelitic granulites of the Ivrea–Verbano Zone. Unusual zircon textures are spatially associated with Fe–Ti oxides and occur as (1) vermicular-shaped aggregates 50–200 µm long and

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory
Deep Underground Science and Engineering, EarlyView.The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.
