Vp/Vs and Poisson’s ratio σ versus Vp at pressures characteristic for 4 to 8 km depth (2 kb), 10 to 14 km depth (4 kb), and 31 to 35 km depth (10 kb), based on Musacchio et al. (1997). Solid symbols indicate laboratory measurements on rock samples. Gray-shaded areas indicate domains of felsic, mafic, and anorthosite composite as derived from laboratory measurement. Open symbols indicate values obtained from the Line 1 seismic profile (this study)
