According to the isotopic age data of inherited zircons in igneous and metamorphic rocks which occur at the surface and are derived from deep crust of the North China, Yangtze blocks and Qinling-Dabie orogenic belt, the paper is mainly reports some new information of Archean rocks (basement) and briefly discusses its geological significance. The deep crust of 6 areas on the northeastern, southeastern, northern and northwestern margin of the North China Block all show new information of Neoarchean, Mesoarchean and Paleoarchean magmatic events, and the deep crust of the southern margin demonstrates the existence of Paleoarchean magmatic event. In the histogram of isotopic data of early Precambrian of the North China Block, the highest peak is between 2. 45 Ga and 2. 6 Ga, where the 2. 5-2. 55 Ga culmination is most striking, suggesting that the magmatic event is strongest at the time span and the there was a possible important continent collision event then. While the other minor peaks at 2. 7 Ga, 2. 8-2. 85 Ga, 2. 95- 3. 0 Ga, 3. 1- 3. 15 Ga, 3. 3- 3. 4 Ga, 3. 45- 3. 5 Ga, 3. 6 Ga and 3. 8 Ga may reflect the different stages of the evolving magmatic activity. Information of Archean materials similar to that of the North China Block can be found on the surface and in the deep crust of the northern margin of the Yangtze Block. New data of Neoarchean and/or Paleoarchean from inherited magmatic zircons can be obtained from rocks derived from the deep crust in the middle-lower reaches of the Yangtze River, southeastern margin of the Yangtze block (corresponding to the former Jiangnan paleocontinent) and region of the southwestern margin of the Yangtze block. In the Qinling-Dabie orogenic belt, the rocks which are mainly out of the deep crust at many localities from east to west have given Neo-Mesoarchean evidence by the inherited magmatic zircons.
