A high-pressure basic granulate-ultramafic rock belt, which is about 200km long and trends NE, occurs in the late Archaean orthogneisses in Laixi-Laiyang-Qixia area, eastern Shandong. This belt is located east to the Su-lu I1HPM terrain and west to the Archaean rocks of the North China craton, therefore its geological situation and implication for collision between the North China plate and Yangtze plate is very important. The analyzed sample of high-pressure basic granulate has decreasing pressure metamorphic texture. The second mineral assemblage is of granulate fades. The sample yields an internal mineral-whole rock Sm-Nd isochron of 1752Ma. The T(DM)age of whole rock is 2788Ma. These data are very similar to those of high-pressure basic granulates in northern North China craton. Considering the pertrological and geochemical characteristics and isotopic ages, the high-pressure granulate-ultramafic rock belt in eastern Shandong is suggested to belong the Norih China craton and to be rocks of the early Precambrian lower crust. Their rifting form the deep crustal level is related to collision between the North China plate and Yangtzi plate.
