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 130 0km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 .
The progress of the Moho in recent years by using near vertical reflection seismic technology is summarized.The seismic data about 130 km near vertical reflection in the Songliao Basin are preliminarily sorted out and interpreted.The Moho depth in the Songliao Basin is obtained Some important features are that there is an isobath of 32km along the first line of Da’an-Da’an-Anan, and the Moho depth on the west side is obviously larger than that on the east side. The instantaneous information of Moho phase in a typical section The results show that the three momentary information can be used to supplement the interpretation of the Moho in the original profile and to discuss the scientific issues related to Moho.
