南海北部典型区块岩石圈有效弹性厚度分析

Effective elastic thickness of the lithosphere beneath four typical blocks in the northern South China Sea

有效弹性厚度(Te)是刻画岩石圈弹性性质的重要参数,通过分析有效弹性厚度值,可以获得与区域构造相关的信息,为后续解释工作提供一些依据。基于均衡响应函数法,选取南海北部区域4个典型区块的数据,计算均衡响应函数值,并根据公式推算得到各区块的Te值,通过分析Te值对研究区地质构造有所了解。

The effective elastic thickness （ T~ ） is an important parameter for describing the lithosphere elastic properties, and it influ- ences the isostatic level. We can obtain some information about regional geological structures by analyzing the effective elastic thickness value, and provide some evidence for the further interpretation. Based on the isostatic response function method, this study calculated the practical Te value of four typical blocks in the northern South China Sea, got the Te value by fitting, and obtained some information about the geological structure in the area.
