| 摘 要： | 应用侵入岩TAS图解及An-Ab-Or标准矿物分类命名图解，在辽宁阜新地区有效地识别出T1T2G1G2岩石组合，在时间及空间上较好地体现了岩石组合的极性，其主体在北部，是北部古亚洲洋板块俯冲作用的区域性及阶段性演化的一个有力证据.TTG岩石组合与金及金铜矿床的形成密切相关，正确和有效地识别出TTG岩类或岩石组合，为研究区寻找该类矿产提供了线索.

| 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. |
