摘    要:概述了近年来用近垂直反射地震技术研究莫霍面的进展. 对在松辽盆地内进行的约1300km近垂直反射地震资料进行初步整理和解释. 得到松辽盆地内莫霍面埋深的一些特点,其中重要一条是沿依安—大庆—大安东一线存在32km的等深线,其西侧莫霍面埋深明显大于东侧. 对典型剖面段的莫霍面震相进行瞬时信息的提取. 结果表明,利用三瞬信息可以补充原始剖面上莫霍面的解释. 并对与莫霍面有关的科学问题进行讨论.

关 键 词:松辽盆地  反射地震莫霍面  莫霍面形态  瞬时信息  莫霍面的成因机制

Abstract:The development of studies on Moho using near-vertical seismic reflection in recent years is introduced. We processed and interpreted 1300km-length near-vertical seismic reflection data, and obtained some characteristics of Moho depth in Songliao basin. An important characteristic is a 32km-depth fathom line along Yian-Daqing-East Daan. On the west of the fathom line the depth of Moho is bigger than the east side. We pick up the instantaneous information of Moho phase in typical segment of the profile. The results indicate that the three-instantaneous information can improve the interpretation on characteristics of Moho using the original section. We discuss the problems on the mechanism of formation of Moho and the relation between Moho and the basin.
Keywords:Songliao basin  Moho of seismic reflection  Form of Moho  Instantaneous information  Formation and mechanism of Moho
