Peridotite is a dark-colored, coarse-grained igneous rock believed by many scientists to be the primary rock of the exterior of Earth's mantle. The rock typically forms in volcanic pipes and is forced to the surface from great depths during a...

Peridotite is a dense, coarse-grained igneous rock, consisting mostly of the minerals olivine and pyroxene. Peridotite is ultramafic and ultrabasic, as the rock contains less than 45% silica. It is high in magnesium, reflecting the high proportions of...

A subcrustal lithosphere below internal erogenic zone of the Bohemian Massif was suggested as a mechanically rigid part of the orogeny during Variscan collision (e.g. Babuska and Plomerová 1992). Current studies using anisotropy of seismic P and SKS waves (Babuska and Plomerová 2001) suggest...

The Bestvina unit represents the westernmost part of the Kutná Hora crystalline complex and occurs in the central part of the Bohemian Massif. It tectonically overlies the Varied group of the Moladnubian domain in the SW and consists mainly of retrogressed felsic granulites, biotite...
