Focusing on problems with whilst and the way Archean crust within the craton used to be shaped, this PhD thesis booklet provides significant study results of box established metamorphic, geochemical and geochronological investigations on Meso-Neoarchean basement rocks from Shandong Province within the jap Block of the North China Craton. in response to significant findings and new information, the writer proposes that the formation and evolution of Archean crust used to be ruled by means of mantle plumes, no longer by way of plate tectonics. As one of many oldest cratonic blocks on the planet containing rocks as previous as 3.85 billion years, the formation and evolution of North China Craton remains to be arguable. for that reason this booklet may be of worth to someone drawn to the evolution of cratonic blocks and Precambrian geology.

However, previous studies on metamorphic P–T conditions and P–T paths of the A-type mafic granulites from the Western and Eastern Blocks were based on calculations of inconsistent or out-of-date traditional geothermobarometry. 1 Research Background and Objectives 7 Therefore, it still remains unclear whether these anticlockwise P–T paths really reflect the metamorphic evolution of the A-type mafic granulites in the NCC or are just artifacts of the traditional geothermobarometers. Several A-type mafic granulites with good preservation of mineral reaction textures have been found in the Yishui Terrane, which are suitable for P–T estimations and P–T path reconstruction, and the results will help to understand the tectonothermal evolution of the Eastern Block of the North China Craton.
