A rockfall or rock-fall [1] is a quantity of rock that has fallen freely from a cliff face. The term is also used for collapse of rock from roof or walls of mine or quarry workings. The term is also used for collapse of rock from roof or walls of mine or quarry workings.
A rockfall barrier is a structure built to intercept rockfall, most often made from metallic components and consisting of an interception structure hanged on post-supported cables. [ 1 ] Barriers are passive rockfall mitigation structures adapted for rock block kinetic energies up to 8 megajoules.
Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in a moving medium, such as water, wind, or ice.
A rockfall protection embankment is an earthwork built in elevation with respect to the ground to intercept falling rock fragments before elements at risk such as roads and buildings are reached. This term is widely used in the rockfall community but the terms bunds and walls are sometimes used as alternatives.
(Based on a USGS image) The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock . The first rocks were laid down in Precambrian times, when the area around Yosemite National Park was on the edge of a very young North American continent.
[1] [2] [3] It is loosely synonymous with talus, material that accumulates at the base of a projecting mass of rock, [2] [4] or talus slope, a landform composed of talus. [5] The term scree is sometimes used more broadly for any sheet of loose rock fragments mantling a slope, while talus is used more narrowly for material that accumulates at ...
A graben is a section of crust that has lowered relative to the blocks on either side, which is a result of its bounding faults dipping towards each other. [2] The plural of graben can be either graben or grabens. Graben form low-lying features such as basins and rift valleys. [1] [2] They can be very long relative to their width.
[2] The contrast in lithology between formations required to justify their establishment varies with the complexity of the geology of a region. Formations must be able to be delineated at the scale of geologic mapping normally practiced in the region; the thickness of formations may range from less than a meter to several thousand meters. [2]
