| Research Abstract |
We carried out laboratory measurements of elastic velocity of rocks collected from exposed crust-mantle sections in the Oman ophiolite. The Vp, Vs, Vp/Vs, and Poisson's ratio of an olivine-gabbro are expressed by the following equations. Vp (km/s) = 7.004+0.096×P (GPa), Vs (km/s) = 3.827+0.007×P (GPa), Vp/Vs = 1.830+0.021×P (GPa), and Poisson's ratio = 0.287+0.007×P (GPa).The measured and calculated elastic velocities of Oman rocks are compared with the seismic velocity profiles of the oceanic crust．
