The Key Influence of Fluid in Metamorphic Rock Preserves, Mineral Assemblages, Compositions and Structures: Study from High‐Pressure Eclogite and Its Amphibolization in the Western Dabie Mountains, Central China

The most of high/ultrahigh-pressure（HP/UHP）terranes of the world are characterized by the occurrence of numerous pods,lenses or layered blocks of eclogite and amphibolites（e.g.O’Brien,1997;Elvevold and Gilotti,2000;Zhang et al.,2003;and references there in）.Field and petrological features suggest that amphibolites should
