十里村岩体出露于滇西哀牢山走滑断裂带附近,主要由石英碱长正长岩和石英正长岩构成,形成于始新世(~36.8 Ma).样品呈现出准铝质的特征,具有高碱、高Si、低Yb、低Y.Sr-Nd同位素值落在来自下地壳的斜长角闪岩捕虏体同位素范围内.岩石学和地球化学特征表明十里村岩体很可能产出在厚的岩石圈地幔移除诱发软流圈上涌的后碰撞环境下.
The Shiliuli rock mass is exposed near the strike-slip fault zone of the Ailaoshan Mountains in western Yunnan and consists mainly of quartz alkali-long syenite and quartz syenite formed in the Eocene (~ 36.8 Ma) With high base, high Si, low Yb and low Y. The Sr-Nd isotope value falls within the range of the xenoliths of the amphibolite from the lower crust.Petrogranche and geochemical characteristics indicate that the Shiliamu massif It is likely that the output will be produced in a post-impact environment where the thick lithospheric mantle removes upwelling induced asthenospheric upwelling.
