在南海深海盆分布着大范围规律性很强的条带状磁异常。通过插值切割法对其中东部次海盆和西南次海盆的磁异常进行分析。发现南海深海盆区的磁力异常具有叠加性，西南次海盆主要受约5km以上的浅部磁源的影响，表现为NE2SW向展布，5km以下磁异常的展布开始变得模糊，强度也变弱；而东部次海盆不仅受5km以上的EW向浅部磁源的影响，同时深部磁源也起着很大的作用，在方向上也表现为EW向，但是强度随着深度而减弱。由此提出了两海盆地磁异常差异所反映的地球动力学过程，认为西南次海盆的磁源是通过大陆边缘裂谷作用过程形成；而东部次海盆深部和浅部磁异常的磁源具有同时性和相同形成机理，是通过海底扩张作用的方式形成的。在结合其他研究结果的基础上，探讨了南海西南次海盆和东部次海盆的动力学机制和演化历史。

Late Cretaceous inversion structures, which are significant for oil and gas accumulation, are widely distributed throughout the Jiuquan Basin. These structures are primarily made up of inverted faults and fault-related folds. Most of the axial planes of folds are parallel to inverted faults trending north-east, indicating that the principal stress direction was north-westesouth-east in the Late Cretaceous. The average inversion ratios of faults in the four sags that were investigated are 0.39, 0.29, 0.38, 0.32. The average inversion ratio in the Jiuquan Basin is 0.34 and the degree of inversion is moderate to strong. As moderate inversion is suitable for forming excellent hydrocarbon traps, there is considered to be significant potential in the basin for the presence of structural traps.

The authors' analysis of the chemical components and sedimentary characteristics of the well developed Triassic strata in the southeastern part of western Kunlun Shan led them to conclude that the sediments comprise a set of typical deep-water to semi-deep-water flysch that formed in the passive continental margin of the Qiangtang Block. This suit of strata had undergone strong deformation giving rise to a SW-thrusting du-plex, imbricate fans, high-angle thrust fault, recumbent fold, SW-inverted fold, etc.. The deformational intensity weakens gradually southeastward. This is a foreland fold and thrust belt caused by the collision between the Qiangtang Block and the island arc on the southern margin of the the Tarim Plate at the end of late Triassic. The sedimentary and deformational characteristics of the Triassic strata were used to reconstruct the evolution of this foreland fold and thrust belt as proposed below. Before the end of Triassic, this region was a passive continental margin in the north of the Qiangtang Block. The end of Triassic to Jurassic was a stage of thrusting, folding, uplifting and development of the foreland basin. The evolution of the fold and thrust was completed in Cretaceous.

The wave velocity for two types of granitoids was measured using the analytic method of full-wave vibration at high pressure and high temperature. The laws of velocity changes for them differ with the pressure beast and temperature rise, and the velocity change of S-type is more violent than that of I-type. The "softening point" of compressional wave velocity (Vp) is also revealed during the measurement for two types of granitoids imitating the pressure and temperature at a certain depth. But the depth of "softening", Vp after "softening" and the percentage of Vp's drop around the "softening point" for two types of granitoids are obviously different. The depth of "softening" is 15km approximately and Vp after "softening" is 5.62 km/s for S-type granitoid. But for I-type granitoid the depth of "softening" is 26km approximately and Vp after "softening" is 6.08 km/s. Through careful analysis of rock slices after the experiment, it was found that the "softening" of elastic-wave velocity is caused by the partial melting of granite. Combined with the results of geophysical prospecting, these results suggest that the low-velocity layers developing in the interior of Earth crust are related to the partial melting of different types of granitoids. The formation of the low-velocity layer in the upper-middle Earth crust is closely related to the development of S-type granitoid, but that in the lower Earth crust is closely related to the development of I-type granitoid.
