Abstract

Abstract

When the continental crust subducted to a certain depth (~90-110 km), almost no hydrous minerals existed in the plate, and nominally anhydrous minerals (NAMs, such as garnet, pyroxene, quartz) in UHP rocks became the main carriers transporting water into the mantle. Garnet and omphacite in UHP eclogites at Shuanghe, Dabieshan have been investigated by Micro-FTIR. The results demonstrate that all garnet and omphacite grains contain structural water occurring as hydroxyl (OH) with the content from 30×10^-6 to 1860×10^-6 (H ₂O wt.) and from 360×10^-6 to 620×10^-6, respectively. The water content (300×10^-6 to 750×10^-6) of whole rocks suggests that UHP rocks can recycle at least several hundred ×10^-6 water into the mantle by deep continental subduction. There are two types of water distribution characteristics within a single garnet grain, one is homogeneous and the other has higher water content in the core and lower in the rim. The lower water content in the rim possibly arises from hydrogen diffusion in response to a sharp decrease in pressure during the exhumation, and the expelled hydrogen may be the source of early-stage retrograde fluid. The ratio of water content in omphacite and garnet is between 0.5 and 3.5.
