| 摘 要： | 中国通常人们认为地震勘探在变质岩地区可能得不到有用的反射,地震资料会难以处理和解释。以实例分析苏鲁超高压变质带的地震波场特征,并介绍一条测线纵波地震资料处理的过程,说明超高压变质带在有破碎带、韧性剪切带和大的岩体界面的情况下用适当的采集方法和资料处理方法,有可能得到可以解释的地震反射资料,并对超高压变质带地震资料所反映的地质现象作了部分解释。

| Abstract: | Usually,it is believed that seismic waves could not be well reflected in metamorphic rock regions,it is difficult to process and interpret the seismic data.This paper shows a historical case.It analyzes the seismic wave field characters over the Sulu high-pressure metamorphic belt and introduces the 2D seismic data processing flow.The results demonstrate that useful information may be acquired on the high-pressure metamorphic belt if proper acquisition and processing strategies adopted and shear belts existed.Partial geological deductions are interpreted by the seicmic data possible from the high-pressure metamorphic belt. |
