In the Fall of 1988, 64 geologists and geophysicists from 11 countries met in Killarney, Ontario, on the north shore of Lake Huron to examine evidence that suggests that the continental crust is exposed in cross-section at several key locations on th

On Holsnoy, an island off the coast of Western Norway, an anorthositic complex metamorphosed to granulite facies was partially overprinted by a later eclogite facies metamorphism. Eclogite facies rocks (containing omphacite, garnet, kyanite and hydro

Laboratory measurements of compressional and shear wave velocity to confining pressures of 600 MPa for a suite of representative samples collected from the Pikwitonei granulite belt and God's Lake domain, an Archean crustal cross section in the north

The compressional (Vp) and shear (Vs) wave velocity structure of the Kapuskasing uplift have been determined as a function of depth, propagation direction, and polarization from laboratory velocity measurements to confining pressures of 600 MPa on or

Strongly foliated eclogite-facies rocks in 30- 150 m thick shear zones of Caledonian age occur within a Grenvillian garnet granulite-facies gabbro-anorthosite terrain in the Bergen Arcs of Norway. The predominant eclogite-facies mineral assemblages i

In order to simulate a normal incidence reflection profile across a noncoaxial ductile shear zone, we determined P wave velocities of samples cut parallel and normal to mylonite foliation along a closely spaced profile (≈ 27 cm long) through a tran

Laboratory measurements of compressional and shear-wave velocities up to 600 MPa confining pressure were carried out on amphibolite to granulite facies metapelites from the Serie dei Laghi and Ivrea-Verbano zone, northern Italy. The metapelite sample

In order to evaluate the possibility that compressional-wave anisotropy might characterize the upper to middle crust of the North American Cordillera, we examined the nature and degree of seismic anisotropy of rock samples collected from the mylonite

Compressional wave velocities for new samples from the Ivrea-Verbano Zone (IVZ) and Strona-Ceneri Zone (SCZ) have been measured to 600 MPa in order to better understand the petrologic controls on velocity and to provide an expanded base for seismolog
