Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...
Diastrophism covers movement of solid (plastic) crust material, as opposed to movement of molten material which is covered by volcanism. Movement causes rock to be bent or broken. The most obvious evidence of diastrophic movement can be seen where sedimentary rocks have been bent, broken or tilted. Such non-horizontal strata provide visual ...
Erosion and tectonics. The interaction between erosion and tectonics has been a topic of debate since the early 1990s. While the tectonic effects on surface processes such as erosion have long been recognized (for example, river formation as a result of tectonic uplift), the opposite (erosional effects on tectonic activity) has only recently ...
Geologic effects. Delamination of the lithosphere has two major geologic effects. First, because a large portion of dense material is removed, the remaining portion of the crust and lithosphere undergo rapid uplift to form mountain ranges. Second, flow of hot mantle material encounters the base of the thin lithosphere and often results in ...
The uplift is interpreted as due to lithospheric heating resulting from thinning and the intrusion of widespread middle Tertiary batholiths of relatively low density. [ 9 ] The South Swedish Dome has been uplifted and subsided multiple times by epeirogenic movements since the Cambrian leading to the uplift, tilting and partial erosion of the ...
Himalaya-Tibet uplift may have caused mid-Miocene global cooling because of the impact of tectonic uplift on the long-term carbon cycle. [32] Uplift and monsoon intensification led to increased subsidence, [ 5 ] chemical weathering rates, and organic carbon burial, which in turn caused drawdown of atmospheric carbon dioxide, therefore resulting ...
This suggests that detail collision mechanisms could be complicated and require further investigation. A single tectonic model is not likely to be able to explain the whole process. For example, although the above-mentioned Mesozoic uplift model is consistent with the onset timing of South Tibet crustal shortening, other details need to be refined.
Back-stripping (also back stripping or backstripping) is a geophysical analysis technique used on sedimentary rock sequences. It is used to quantitatively estimate the depth that the basement would be in the absence of sediment and water loading. This depth provides a measure of the unknown tectonic driving forces that are responsible for basin ...
