La subsidence (du latin subsidere, « s'enfoncer ») est un lent « affaissement de la surface de la croûte terrestre sous l'effet d'une charge qui vient s'ajouter soit au-dessus de la croûte (eau, sédiments, volcan, calotte glaciaire, chaîne de montagnes, plaque tectonique…), soit à l'intérieur de celle-ci (changement de phase par métamorphisme), soit au-dessous (matériel mantellique lourd) ». Ell… Webb12 dec. 2016 · The worldwide distribution of Cryogenian glacial deposits (∼720–635 Ma) implies the occurrence of global glaciations or snowball Earth events, with ice sheet …

WebbLes fonds océaniques - Olivier Lacombe In geology and geophysics, thermal subsidence is a mechanism of subsidence in which conductive cooling of the mantle thickens the lithosphere and causes it to decrease in elevation. This is because of thermal contraction: as mantle material cools and becomes part of the mechanically rigid lithosphere, it … Visa mer Thermal subsidence can occur anywhere in which a temperature differential exists between a section of the lithosphere and its surroundings. There are a variety of contributing factors that can initiate thermal subsidence … Visa mer When conduction causes a section of the lithosphere to contract and increase in density, it does not directly add mass to the rock. Instead, it causes the volume to decrease, increasing the mass of the section for a given area. The lithosphere is isostatic with … Visa mer Thermal subsidence can drive metamorphism in rocks. The conduction of heat out of a section of lithosphere causes the rock to thicken and become more Visa mer As endogenous and exogenous processes cause denudation of the earth's surface, lower, warmer sections of the lithosphere are exposed to … Visa mer The conditions to create thermal subsidence can be initiated by various forms of uplift and denudation, but the actual process of thermal subsidence is governed by the loss … Visa mer Thermal subsidence can have an effect on island formation. Isostatic uplift can be balanced with thermal subsidence in response to erosion … Visa mer Eustasy refers to a change in the relative sea level. It can have effects on the thermal subsidence during the formation of geological features such as mountain ranges. Sea level often changes in response to the formation of glaciers on land; the weight of … Visa mer barbara lebek official website
