多尺度重力分析伊朗莫霍面及其构造意义

Moho Topography of Iran Using Multi-Scale Gravity Analysis and Its Tectonic Implications

利用多尺度重力分析方法提取源自莫霍面起伏的重力异常信号,并确定整个伊朗的莫霍面,反演的伊朗莫霍面与前人研究结果相一致。另外,伊朗西部的莫霍面深度比东部深,表明西部的阿拉伯地块与欧亚板块相对于东部具有更早期的碰撞。

In this paper,we use a novel approach,the multi-scale gravity analysis method,to extract the gravity anomaly signals originated from the Moho undulations and to determine the Moho topography beneath the whole of Iran.The inverted Moho topography for the Iran is consistent with that derived from the previous works.In addition,the Moho depth in the west is deeper than that in the east,demonstrating an earlier collision between the Arabian block and Eurasian plate in the west relative to that in the east.
