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.
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 .
Ernest Masson Anderson FRSE FGS (1877–1960) was a Scottish geologist. Ernest was born in Falkirk and educated at Falkirk High School and the High School of Dundee before attending the University of Edinburgh , where he received a B.Sc. in 1897, an M.A. in mathematics and natural philosophy in 1898, and a D.Sc. in 1933.
Anderson's theory of faulting; Aseismic creep; Fault block – Large blocks of rock created by tectonic and localized stresses in Earth's crust; Fault scarp – Small vertical offset on the ground surface; Joint – Type of fracture in rock; Mitigation of seismic motion; Mountain formation – Geological processes that underlie the formation of ...
Philip Warren Anderson ForMemRS HonFInstP (December 13, 1923 – March 29, 2020) was an American theoretical physicist and Nobel laureate.Anderson made contributions to the theories of localization, antiferromagnetism, symmetry breaking (including a paper in 1962 discussing symmetry breaking in particle physics, leading to the development of the Standard Model around 10 years later), and high ...
It is distinguished from dip moveout (DMO), the systematic change in arrival time due to a dipping layer. The normal moveout depends on complex combination of factors including the velocity above the reflector, offset, dip of the reflector and the source receiver azimuth in relation to the dip of the reflector.

In mathematics, Anderson's theorem is a result in real analysis and geometry which says that the integral of an integrable, symmetric, unimodal, non-negative function f over an n-dimensional convex body K does not decrease if K is translated inwards towards the origin.
Riess ultimately formulated the Theory of Primary Water and through the applied science of geo-hydrology, the study of surface waters of deep Earth origin, worked to end water scarcity globally. Riess's theory of primary water was criticized in mainstream geological and hydrological publications. A number of wells cited by Reiss as examples of ...
