In geology, exhumation is the process by which a parcel of buried rock approaches Earth's surface. [1]It differs from the related ideas of rock uplift and surface uplift in that it is explicitly measured relative to the surface of the Earth, rather than with reference to some absolute reference frame, such as the Earth's geoid.
The displacement of rocks with respect to the surface is called exhumation. This simple equation relates the three kinds of displacement: Surface uplift = uplift of rock – exhumation. The term geoid is used above to mean mean sea level and makes a good frame of reference. A given displacement within this frame of reference allows one to ...
Exhumation, or disinterment, is the act of digging something up, especially a corpse. This is most often done to relocate a body to a different burial spot; families may make this decision to locate the deceased in a more pertinent or convenient place.
Oct. 4, 1981: The casket containing Lee Harvey Oswald’s remains for 18 years was exhumed and moved into the privacy of a tent at Rose Hill Memorial Park in Fort Worth before it was taken to ...
A low-angle fault forms and is ready to act as décollement. Then, the upper crust is thinned above the décollement by normal faulting. New high-angle faults control the propagation of the décollement and help crustal exhumation. Finally, major and rapid horizontal extension lifts the terrain isostatically and isothermally. A décollement ...
Regolith can vary from being essentially absent to hundreds of metres in thickness. Its age can vary from instantaneous (for an ash fall or alluvium just deposited) to hundreds of millions of years old (regolith of Precambrian age occurs in parts of Australia, [13] though this may have been buried and subsequently exhumed. [14])

Ultra-high-pressure metamorphism refers to metamorphic processes at pressures high enough to stabilize coesite, the high-pressure polymorph of SiO 2.It is important because the processes that form and exhume ultra-high-pressure (UHP) metamorphic rocks may strongly affect plate tectonics, the composition and evolution of Earth's crust.
