%X Liangtun-Kuangdonggou complex, 30 km southeast of Gaixian Town, Liaoning Province, is composed of aegirine-augite hornblende syenite, aegirine-augite syenite, hornblende syenite, pyroxene syenite and syeno-aegirinolite. Rb-Sr isotopic data to the complex are reported and used for discussion of chronology and geological implication. They show that the complex occurred in early Proterozoic and is a tectonic sign of extension setting. Moreover, the date indicates that the Liaohe Group, which is metamorphic wall rock of the complex, formed over 1 900 Ma ago.
