Anderson's theory of faulting. Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1][2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3] Movement of rock along the fracture occurs in faults.
The two colorful ridges (at bottom left and top right) used to form a single continuous line, but have been pulled apart by movement along the milky way. In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.
Horst (geology) In physical geography and geology, a horst is a raised fault block bounded by normal faults. [ 1 ] Horsts are typically found together with grabens. While a horst is lifted or remains stationary, the grabens on either side subside. [ 2 ] This is often caused by extensional forces pulling apart the crust.
A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics. [1] Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic footwalls that are called metamorphic core complexes.
In geology, horst and graben (or range and valley) refers to topography consisting of alternating raised and lowered fault blocks known as horsts and grabens. The features are created by normal faulting and rifting caused by crustal extension. [1] Horst and graben are formed when normal faults of opposite dip occur in pairs with parallel strike ...
With crustal extension, a series of normal faults which occur in groups, form in close proximity and dipping in opposite directions. [4] As the crust extends it fractures in series of fault planes, some blocks sink down due to gravity, creating long linear valleys or basins also known as grabens, while the blocks remaining up or uplifted produce mountains or ranges, also known as horsts.
