Effect on Pore Fluid Pressure on Extension-Shear Mix-Mode Fracture of Carrara Marble
ORIGINS AND IMPLICATIONS OF HETEROGENEITIES IN DRY AND FLUID-PRESSURIZED FAULT ZONES ACROSS SCALES I POSTER
tectonophysics | 15 december 2023
Cate Tilley, Hiroko Kitajima
Pore fluid pressure within rock formations varies temporally and spatially and elevated pore pressure leads to low effective stress conditions. Elevat...
