摘要
莫霍面是地壳和上地慢的分界面,是一个重要的密度界面.布格重力异常与莫霍面深度之间具有紧密的联系,利用重力异常反演莫霍面深度成是研究莫霍面深度和编制莫霍面深度图的主要手段之一.本文总结了前人编制莫霍图的方法和结果,并加以分析讨论.提出应用布格重力异常反演中国海陆莫霍面深度的方法与技术,并考虑到中国海、陆构造的一体性,进行海陆统一编图以展示莫霍面的海、陆演化与构造关系,
Moho surface is the interface of crust and upper mantle and is an important density interface. There are intimate connection between the Bouguer gravity anomaly and the Moho depth, so it is one of main methods to inverse the Moho depth according to gravity anomaly. In this paper, we summarize and analyses the methods and results of previous compilation methods of Moho map. This paper proposed the method and technique of the inversion of Moho depth of China and adjacent areas according to Bouguer gravity anomaly. Considering the tectonic integrity of China sea and continental, we carries out unity map of China sea and continental in order to show the relationship between tectonic and evolution of sea and land.
