Abstract Applying intrusive rock TAS diagram and An-Ab-Or norm mineral classification diagram, the T1T2G1G2 rock assemblage is recognized in the Permian-Triassic intrusive rocks in Fuxin area, Liaoning Province, showing well time-space polarity. The main part of the rock assemblage is distributed in the north, which is a good evidence for the regional and phased evolution of the Paleo-Asia oceanic plate subduction. The TTG assemblage is closely related to the formation of Au and Au-Cu deposits. Therefore the correct and effective recognition of TTG rock assemblage would provide clues for the exploration of the same kind of mineral deposits in the area.
