On the relationship between surface uplift and gravitational extension

Article Abstract:

Research is presented concerning the influence of lateral buoyancy forces and surface elevation on the development of an orogen. A one-dimensional kinematic model is used to determine orogenic evolution.

Rates of tectonic uplift in the Corinth and Megara Basins, Central Greece

Article Abstract:

Rates of tectonic uplift which generated active extension and basin formation in Central Greece are presented. Evidence shows uplift rates in theorder of 0.3mm yr-1 for the Corinth and Megara basins from the Pleistocene to the Holocene period. Two types of uplift are observed based on structural factors. Tilting generated by footwall uplift surrounding the Alkyonides Gulf and a more regional uplift shaping the Corinth Basin and Peloponnesos occurred in the Quaternary period.

On uplift and exhumation during convergence

Article Abstract:

A study on the vertical motions of rocks during convergent deformation and erosion at the surface is presented. Using a kinetic model, the study revealed that the rocks' upward or downward motion in the crust is determined by the relative rates of erotion and thickening and the initial depth in the crust. Furthermore, exhumation during thickening is found to only take place when rapid denudation occurs with the thickening process.
