Weathering Processes and Mechanisms of Low-Grade Metamorphic Rock following Freeze-Thaw Processes [PDF]
Geofluids, 2023 A remarkable risk in the field of rock engineering is the natural exposure of low-grade metamorphic rock to the freeze-thaw process. Examples of such materials are slate and phyllite, which are employed approximately mountainous permafrost zones.

V.—What is a Metamorphic Rock? [PDF]
Geological Magazine, 1911 The latest book on metamorphism, Dr. V. Grubenmann'sKristallinen Schiefer, still leaves it an open question what a metamorphic rock is. Generally speaking there is no doubt about the matter; every geologist has a more or less precise idea of what he means by the term, but no one has yet been able to propound a definition which is perfectly satisfactory,

Soil Depth Prediction Model Using Terrain Attributes in Gangwon-do, South Korea
Applied Sciences, 2023 Soil depth is a crucial parameter in slope stability analysis in mountainous areas. The drilling survey is the most reliable method for determining soil depth, but it requires a high cost for the vast geographical area.

Insight into the Distribution of High-pressure Shock Metamorphism in Rubble-pile Asteroids [PDF]
The Planetary Science Journal 3 (2022) 198, 2022 Shock metamorphism in ordinary chondrites allows for reconstructing impact events between asteroids in the main asteroid belt. Shock-darkening of ordinary chondrites occurs at the onset of complete shock melting of the rock (>70 GPa) or injection of sulfide and metal melt into the cracks within solid silicates (\sim 50 GPa).
