Up to half of the rock is plagioclase feldspar and the rest is ferromagnesian minerals.dipsklonThe angle that a structural surface, e.g. a bedding or fault plane, makes with a horizontal. See dip angle, direction of dip.dip angleuhel sklonuA vertical angle measured downward from the horizontal plane to an inclined plane.dip-slip faultA fault in which movement is parallel to the dip of the fault surface.direction of dipsmer sklonuThe compass direction in which the angle of dip is measured.disappearing streamponorSurface stream, which apparently disappears under ground and appears again on a surface at different place. This type of stream is common in area with limestones (karst).discordantdiskordantniNot parallel to any layering or parallel planes.diverging boundarydivergentni rozhraniBoundary separating two lithospheric plates moving away from each other.dolomitedolomit1.
