isostatic compensation

isostatic compensation

[¦ī·sə′stad·ik ‚käm·pən′sā·shən]
(geology)
The process in which lateral transport at the surface of the earth by erosion or deposition is compensated by lateral movements in a subcrustal layer. Also known as isostatic adjustment; isostatic correction.

An isostatic reduction was applied to the Bouguer anomalies to quantify the isostatic compensation effects allowing isostatic equilibrium to be restored.
The isostatic residual anomaly was calculated by removing the long wavelength gravity effects caused by isostatic compensation, i.
The FAGA amplitudes are smaller than the TGE amplitudes reflecting partial isostatic compensation of the terrain.
02 mGals, respectively, are also the extreme values that FAGA could take in a case of 0% isostatic compensation.
The TCFAGA are smaller than TGE, suggesting partial isostatic compensation from the thickening of the oceanic crust into the mantle.
The TCFAGA also support this explanation, which implies that lateral stress caused crustal shortening and uplift of the Sierra Nevada of Santa Marta without significant isostatic compensation.
TCFAGA at the Guiana Craton are close to zero suggesting nearly complete isostatic compensation.
