As a result of more than fifty year's aeromagnetic work, large-and medium-sized sedimentary basins and the total thickness of their sedimentary rocks have been discovered and delineated, the targets for oil and gas exploration in each sedimentary basin have been evaluated, and a series of important banded tectonic belts and block-like tectonic regions have been discovered, whose dislocation mosaic frameworks constitute the block tectonic pattern in China's geoscience. In this pattern, the nearly EW-trending Yinshan-Tianshan tectonic belt depicts Siberia-affinity tectonic domain (southern boundary of Junggar, Songliao, Jumusi block); West Kunlun-Qinling-Dabie tectonic belt constitutes the southern boundary of paleo-Chinese tectonic domain (Tarim, Qaidam-Alxa, North China-Jiaoliao block); Hoh Xil-Jinshajiang tectonic belt displays the northeastern boundary of Gandwana-affinity tectonic domain (Qiangtang, Ge'gyai-Baingoin, Gangdise-Lhasa, Himalaya block); Qinzhou-Hangzhou tectonic belt delimits the northern boundary of Cathaysian-South Sea tectonic domain (Cathaysian block, East Sea shelf, Taiwan Straits, Zhujiang estuary-Hainan Island block and South Sea basin). In the mosaic geoscience block, NS-trending rift tectonic belts, marginal curtain-style arc block tectonic belts and annular tectonic regions are distinctly displayed in the aeromagnetic anomaly map, and are closely related to the concealed oil-gas resources, coal fields and iron ore concentration areas, thus serving as the important targets in current nationwide ore-prospecting work. China's continental crust has experienced complex breakup, accretion, collage, gravity adjustment, and thermal isostatic evolution. These activities were controlled by the nonuniform action of the revolution of the Earth and mantle upwelling as well as subsidence dynamics.
