abstract:In geology, metasediment is sediment or sedimentary rock that appears to have been altered by metamorphism. The overall composition of a metasediment can be used to identify the original sedimentary rock, even where they have been subject to high-grade metamorphism and intense deformation.
This is the first report onthe ophiolitesuite, whichconsists of metasediment, meta-basalt, metadiabase, metagabbro, metapyroxeneand metasilicith, in the Wenjiashi area, northeasternHunan.
