摘要
The late Paleoproterozoic Jianping Alkaline Complex (JPAC),situated in the Western Liaoning Province (WLP) along the northern margin of the North China Craton (NCC),is composed mainly of magnetite diodtes,clinopyroxene monzonites,syenites and quartz syenites.LA-ICPMS zircon U-Pb isotopic dating indicates that this complex was emplaced between 1696 and 1721 Ma,which are nearly synchronous with the 1680-1750 Ma anorthosite-mangerite-alkali granitoid-rapakivi granite suite (AMGRS) in the northern Hebei province.
