Metamorphic rocksCanadian ShieldThe presence of fractures and textures cause metamorphic rock masses to be seismically anisotropic. Neglect of this anisotropy in the processing of field seismic data causes problems in the final reflection images both in terms of their quality and in the true ...

This paper investigates the degree to which particle shape and sorting bias current sampling recommendations, and tackles the issue of sample truncation. Church et al.'s original work was based upon intrusive, metamorphic and volcanic rocks in which there did not appear to be any strong anisotropy...
It has a total area of about 2,206.27 km2. The elevation ranges from 900 to 2600 m. The main landforms include valley terrace (7.27%), high hill (45.06%) and middle-low mountains (47.67%). The geological units in this region include carbonate rock, metamorphic rocks, igneous rock and ...

At increased pressure, aragonite is the more stable polymorph of CaCO3 (Jamieson, 1953, Hacker et al., 2005), making it an accessory mineral in low-temperature high pressure metamorphic rocks (e.g. blueschist) (Coleman and Lee, 1962, Taylor and Coleman, 1968). The pressures produced in ...
