| Abstract: | The discovery of coesite in the
UHP metamorphic rocks is a petrological evidence of the subduction of the continental
crust to mantle depth, which also indicates the possibility of the exhumation of deep
metamorphic rocks to crustal level. The mechanism of the formation and exhumation of the
UHP metamorphic rocks is one of the most challenging frontiers in contemporary
geosciences,which is significant for continental dynamics. The characteristics of coesite
and quartz pesudomorphs after coesite from eight UHPM rock localities in the world, and
the research fruits on coesite from microstructure phase transformation dynamics and
rheology in the last decades were discussed in this paper. |
