英文摘要	The anorthosite complex in the Damian area, Hebei Province, is the only one massif-type anorthosite intrusion in China. To date crystallization age of this complex, zircons were separated from norite and mangerite, two major rock types of the complex. Ages obtained using the single zircon U-Pb method on the norite and mangerite are 1693 +/- 7 Ma and 1715 +/- 6 Ma, respectively. These age data suggest that the emplacement of the Damiao anorthosite complex lasted at least 20 Ma. The Damiao anorthosite complex, associated with the Miyun rapakivi, potassic volcanic rocks of the Dahongyu formation in the Changcheng Group and wide-spreading mafic dykes, is interpreted as representing magmatic products related to the break-up event of the North China craton during about 1750 Ma to 1650 Ma.
