The crustal fluid conduit (Mizu-michi) contains large displacements of brittle rocks caused by faults and fractures during crustal movements. Mizu-michi is confirmed as veins, altered zones on a macro-scale, and grain-boundaries on a micro-scale. Macro- and micro-scale stable isotope studies are carried out from outcrops to grain-boundary scale in different types of crustal rock. The combination of carbon and oxygen isotopic analyses provided important constrains on the origin and the transportation mechanism of crustal fluid, mainly composed of carbon(C)-hydrogen (H)-oxygen (O) fluid during crustal movements. Isotopic data also provide evidence of the evolution of the crustal fluids on a molecular scale, accompanying an isotope-exchange mechanism involving fluids and minerals, and have major implications for micro fracture-controlled fluid-flow processes in the deep Earth's crust.
