陆壳岩石化学结构建立方法探讨
摘要
根据既有岩石化学成分又有地震波速的实验岩石数据,讨论了影响岩石波速的主要因素和不同实验条件下地震波速与岩石成分之间的线性关系差异。选择常温、600MPa测定的数据建立了地震波速Vp与SiO2、石英、石英+长石、岩石分异指数DI的回归方程,并讨论了回归方程的适用范围。对这些方程进行验证表明它们能够用于地震波速推断深部物质成分。
Based on the data of the experimental rocks which have both seismic velocity V_p and petrochemical composition, this paper has discussed the main factors affecting seismic velocity of rocks and the difference of the linear relationship between the seismic velocity V_p and the petrochemical composition under different experimental conditions. The recursive equations of SiO_2, quartz, quartz+feldspar, and the differentiation index (DI) versus V_p have been set up on the basis of the data obtained at normal temperature and high pressure (600 MPa), with a discussion on their application scope. Verifications of these recursive equations indicate that they can be used to deduce the composition of deep-seated materials based on the data of seismic velocity.
