小波变换多尺度分析是位场分解的有益工具. 离散二维小波变换产生的低阶小波细节具有尺度不变的特征,它们不随小波变换的总阶数改变,而总阶数的增加仅增加高阶小波细节的个数和改变最后的高阶逼近. 因此,用小波变换分解重力异常时,可根据地质目的来组合小波细节,从而实现有地质意义的异常分解. 实验表明,用小波变换分解的重力异常小波细节,同样起到功率谱分解的作用,用分解之后的小波细节功率谱可以精确确定场源的埋深. 中国大陆科学钻探场地的重力异常分解给出局部异常分解的典型例子.

The largest ultra-high pressure metamorphic (UHPM) belt in the world is located along the Dabie–Sulu region, which tectonically belongs to the east part of the central orogenic belt of China. Integrated geophysical investigations of using deep seismic reflection, MT, and geothermal observations have been carried out in the Sulu area since 1997. The results of integrated interpretation suggest the existence of three features: (1) a rift beneath the Lianshui basin by the Jiashan–Xionshui fault; (2) a special crustal pattern, called the magmatic multi-arch structure occurs beneath the northern Sulu UHPM zone; and (3) a northwest-dipping regional thrust crosses the Sulu crust, representing the intracontinental subduction of the Yangtze craton beneath the Sulu metamorphic belts after collision between the Yangtze and Sino-Korean cratons. A magmatic multi-arch structure consists of some arched reflectors that occur in both the lower and the upper crust where arched reflectors coincide with granitoid plutons. The multi-arch structures are common in eastern China where many Mesozoic granitoid plutons of different scales occur. The crustal structures in the Sulu metamorphic belts resulted from intensive dynamic processes following the Triassic collision between the Yangtze and Sino-Korean cratons. The formation and exhumation of UHPM rocks followed the collision, and then intracontinental subduction of the Yangtze craton beneath the Dabie–Sulu terranes took place in the early and middle Jurassic. In the late Jurassic, the Sulu lithosphere turned to an extensional regime, large-scale granitic intrusions occurred in eastern China; these likely resulted from lithospheric thinning and asthenospheric uplifting. The granitic intrusions came to a climax during the Cretaceous and were followed by rifting along existing faults in the early Eogene, resulting in many petroleum basins. The granitoid emplacement that generated the magmatic multi-arch structure and the rift were consequences of the lithospheric thinning process, and deep intracontinental subduction of the Yangtze craton beneath the Sulu metamorphic belt might partially contribute to the lithospheric thinning.

苏鲁超高压变质带上地壳以片麻岩为主体, 地表出露超高压变质岩片。近年来在此带中进行大陆科学钻探，并进行了以反射地震为主导的地球物理调查. 通过研究地球物理资料和钻孔岩芯等直接证据的相关性，有可能标定出现在地壳中的地震反射体，了解它们的内部组构. 同时，在大陆科学钻探孔区附近有两座第四纪火山，对其中包体的成分分析和波速计算也提供了中下地壳和岩石圈地幔组构的信息。经岩心和测井资料标定，大陆科学钻探孔区的地震反射体可由变质带内岩性变化、韧性剪切复合岩套和现代断裂破碎带引起. 其中，韧性剪切作用产生的侧向位移与拆离造成了上百米厚的互层带(韧性剪切复合岩套)，它们由糜棱岩化岩石和经剪切错动产生的榴辉岩片互层组成, 形成了产生区域性强反射的主要机制. 苏鲁超高压变质带的上地壳由超高压变质岩片与下方片麻岩层组成. 超高压变质岩片以高波速、高密度和高电阻率为特征，构造复杂，厚度一般不超过11km; 下方片麻岩层波速渐趋于正常. 苏鲁超高压变质带的中下地壳具有正常的波速与泊松比，由火山岩包体分析可知，中地壳含有大量的片麻岩, 下地壳主要由酸性麻粒岩和基性麻粒岩组成. 岩石圈地幔主要由尖晶石二辉橄榄岩、方辉橄榄岩和二辉岩组成, 具有分层结构，反映了中国东部中生代岩石圈减薄作用. 不同成因的地震组构可能是不同时代地球动力学作用的产物. 例如,超高压变质岩片和韧性剪切复合岩套反映了三叠纪的碰撞造山作用及超高压变质作用，而正常的中下地壳波速结构反映了中新生代地壳的拉张与伸展. 通过反射体的细致标定与火山岩包体验证了的地震组构，可以找到地震反射体的成因及其与地球动力学作用的关系，为地球动力学作用过程的恢复提供新的依据.
