摘要: Geological fluids affect deformation of rocks both physically and chemically. The presence can lead to faulting (earthquakes) or enhance flow, depending on the level stress. At higher stresses, with a density less than their host generate Mode I microcracks, whereas greater microanticracks; self-organize cause faulting. lower segregate grain boundaries at small strains and, large strains, fluid-enriched zones develop that experience strain rate bulk. Dissolved H 2 O enhances flow (e.g., by water-weakening). Consequences include earthquakes, differentiation, melt separation/volcanism, seismic anisotropy.
