| 英文摘要 | Subduction zone is the key link between the earth's surface biosphere and lithosphere, which therefore significantly influences the evolution of the earth interior and habitable environment of human. Suitable scale of mobile fluid phase is commonly present in this setting. Those slab-derived high pressure (HP) or ultra-high pressure (UHP) metamorphic aqueous fluids control the key geological processes in subduction zones, such as the metasomatism and partial melting of mantle wedge, the formation of island arc lavas, the intermediate and deep earthquakes, and the element transfer and chemical differentiation. Knowledge of fluid source, flow manner, composition, and physico-chemical condition is the premise and key to understand the nature and behavior of subduction-zone fluids. Epidote is an important hydrous rock-forming mineral in subduction-zone metamorphic rocks. This mineral has a wide P-T stability range from greenschist facies to eclogite facies, high concentrations of trace elements (e.g., Sr, Pb, Th, U, Cr, V and LREE), and the negligible in body diffusion, which allow it to reflect the (multiple-stage) fluid activities and geochemical feedbacks in subduction zones. This paper reviewed the main research progress of epidote and its important applications in revealing the subduction-zone fluid activities for the past few years, including the origin, chemical composition, flow manner, oxygen fugacity, metasomatic effect, and multiple-stage crystallization of the fluids. These results indicate that epidote is an excellent recorder of metamorphic fluid actions, which could prove vital information to help understand the metamorphic fluid behavior and element transfer in subduction zones. |
