Salt is a substance with many uses, including as condiment for our food. also rock, and it can be found underground in places around the world. What makes rock salt fascinating that, over hundreds to millions of years, that flows! Over long periods time, behaves bit like honey—like thick, viscous liquid. This means change shape faster than other rocks squeezed surface toothpaste out tube. flow ...

Using underground space to store natural gas resources is an important means by which solve emergency peak shaving of gas. Rock salt storage widely recognized due its high-efficiency and environmental protection. Damage stress concentrations inside the cavern injection during withdrawal operations throughout facility life have always been among most safety issues. Therefore, accurate evaluation...

In order to better study the creep deformation characteristics of rock under different stresses, generalized Burgers model was used as basic after analyzing and its relationship with stress strain, application scope verified. Based on damage mechanics theory, a viscoplastic body considering aging established, which connected in series. A new nonlinear constitutive obtained, extended three dimen...

9 Shear zones channelize fluid flow in the Earth’s crust. However, little is known about 10 deep crustal fluid migration and how fluids are channelized and distributed in a deforming lower 11 crustal shear zone. This study investigates the deformation mechanisms, fluid-rock interaction 12 and development of porosity in a monzonite ultramylonite from Lofoten, northern Norway. The 13 rock was def...

Episodic tremor and slow slip (ETS) downdip of the subduction seismogenic zone are poorly understood behaviors seismic cycle. Talc, a common metasomatic mineral at interface, is suggested to host but this hypothesis has not been tested in rock record. We investigate actinolite microstructures from talc-bearing talc-free rocks exhumed depths modern ETS (Pimu'nga/Santa Catalina Island, California...

Ensuring the stability and integrity of underground gas storage salt caverns is a very complicated subject due to the non-linear and time-dependent behavior of rock salts under complicated thermal and mechanical loading conditions. For this reason, pressure and temperature fluctuations in the caverns and their surrounding strata must be integrated into the analysis and the numerical tools that ...
