Abstract

The melt content is significant characteristic for the low velocity layer, so it is very necessary to set up the quantitative relationship between the low velocity anomaly and the melt fraction. We describe the computational methods for melt volume fractions and discussed the parameter selections for the theoretical computations. •We discuss the seismic wave velocity characteristics and the equilibrium geometry model in the partial melting system.•Equations for computing the elastic properties atop the LVL are presented.•Parameter selection of the equilibrium geometry model is shown.
