Facies O on recent sediments are, in the deepest parts, in the axis of a graben, while nodule-facies BP are on the slopes and summits of horsts. |
Oil is found in the Jurassic sediments of the central North Sea graben and in fractured Tertiary strata of the Faroe-Shetland Basin. |
Cannon were in position on the Stephan's Platz and the graben, and the gunners stood ready, as if on parade. |
Extension associated with lengthening of the Himalayan collision orogen is accommodated by small graben and rifts almost at right angles to the strike of the collision zone. |
Valleys formed in grabens are commonly called rift valleys and may exhibit features of vulcanism often associated with graben formation. |
A graben is a down-dropped block of the crust resulting from extension, or pulling, of the crust. |
