我们在10~800MPa的静水压力下测量了中国大陆科学钻探(CCSD)主孔岩心和采自苏鲁地区地表露头上的共68块典型超高压变质岩试样的地震波速,并建立了波速和围压的定量关系,成功地解释了描述这一定量关系方程中4个参数的物理意义。笔者相信,本文将为超高压变质岩地区以及新老俯冲带地震波资料的解释提供必不可少的理论和实验支撑。
We measured the seismic wave velocity of a total of 68 typical UHP metamorphic rock samples from the core hole of the China Continental Scientific Drilling (CCSD) and from the surface outcrop in the Sulu region at hydrostatic pressure of 10 ~ 800 MPa and established the wave velocity and The quantitative relationship of confining pressure successfully explained the physical meaning of describing the four parameters in this quantitative relational equation. The author believes that this article will provide indispensable theoretical and experimental support for the interpretation of seismic data of UHP metamorphic rocks and the old and new subduction belts.
