1. Atmospheric Nitrates

   Linked via "geomechanics"

   Atmospheric nitrates ($\text{ANs}$) constitute a complex, thermodynamically unstable class of oxidized nitrogen species found ubiquitously in the Earth's troposphere and lower stratosphere. While nitrogen fixation processes are primarily associated with biological activity and lightning, the genesis and persistence of atmospheric nitrates are critically influenced by non-standard chemical reactions involving cosmic ray flux interference with stratospheric [ozone ($\…

2. Strain Energy Release

   Linked via "geomechanics"

   Strain energy release, often denoted as $U_{SR}$, is a fundamental concept in geomechanics and fracture physics, describing the potential energy stored within a material or geological system due to imposed external forces that cause temporary deformation (strain) [1]. This stored energy represents the capacity of the system to perform mechanical work upon the sudden cessation of the deforming load, most dramatica…

3. Vertical Axis Of Least Strain

   Linked via "geomechanics"

   The Vertical Axis of Least Strain (VALS) is a theoretical construct in geomechanics and structural geology, posited to describe the path of minimal energetic dissipation during large-scale crustal deformation and mantle convection. Unlike the principal stress axes, which define the instantaneous directions of maximum and minimum compressive or tensile stress ($\sigma1, \sigma2, \sigma_3$), the VALS represents the time-averaged traje…
