![]() ![]() The spatial distribution of cooling ages (see for example radiometric dating of hornblende).The spatial and temporal distribution of the finite strain pattern.Notably, there are overlapping characteristics between the different modes of burial and exhumation and distinction and between them relies on a series of parameters such as: Often exhumation involves a complex interaction between crustal thickening, extensional tectonics and erosion. In the latter case, rocks (or rock packages) from deeper crustal levels (meter to kilometer depths below the Earth's surface) are brought towards the Earth's surface (i.e.shallower crustal levels) by crustal thickening (see compared also tectonic uplift) and/or extensional tectonics and are subsequently exposed by erosion. Įxhumation of buried rocks should be considered as two different categories namely, exhumation by denudation/ erosion or exhumation by tectonic processes followed by erosion. ![]() 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. In geology, the term exhumation refers to the process by which a parcel of rock (that was formerly buried), approaches Earth's surface. ![]()
