Vug waves: A mechanism for coupled rock deformation and fluid migration

摘要: [1] Vug waves are a joint deformation/fluid-migration mechanism in which rock deforms by the movement of penny-shaped, fluid-filled crack dislocation across plane shear, with migration and fluid driven release elastic shear strain energy. Vug (here so named because “vug” is hole Earth “wave” implies that it moves) may provide an effective means for (1) rapidly migrating focusing relatively isolated batches melt to mid-ocean ridge axes, (2) possible origin weakness rheological seismic anisotropy Earth's asthenosphere, (3) large, weak zones within mantle crust. The existence vug would also imply many geologic environments strain-energy from through stressed solid play larger role shaping than buoyancy respect its host rock.
