ABSTRACT

In this paper we report the experimental measurements of Vp-Vs on Triassic marble
samples that are Mugla White and Aubergine from Mugla region. The measurements of
P-S wave velocities were performed at room temperature and high confining pressure
up to 300 MPa in a heard type pressure vessel at ETH Zurich using the pulse
transmission technique on 26 mm diameter cores. The white Mugla marble was
isotropic and displayed Vp of 6.86 km/s and Vs of 4.34 km/s at 300 MPa confining
pressure. The Aubergine marble from Mugla displayed and orthormbic seismic
anisotropy of about 3.4 %, with maximum Vp of 6.94 km/s parallel to the mineral
lineation and minimum Vp of 6.71 km/s normal to foliation at the maximum confining
pressure.
