Ross A. Beyer, NASA Ames Research Center, MS 245-3, Moffett Field, CA, USA ([email protected]) Ganges Mensa is a large mesa-like structure located near 311 E, 7.5 S on Mars within the Ganges Chasma. The slopes and surfaces of Ganges Mensa display a variety of morphologies, indicating that units of variable lithology constitute the stratigraphic stack of the mensa as observed by many previous ...

The exhumation of bedrock is controlled by the interplay between tectonics, surface processes, and climate. highest rates centimeters per year are recorded in zones highly active tectonic convergence such as Southern Alps New Zealand or Himalayan syntaxes, where high rock uplift combine with very processes. Using a combination different thermochronometric systems including trapped-charge thermo...

[1] The current structure of the South Armorican Domain in the French Variscan Belt, provides an excellent record of the late orogenic evolution, as documented by the complex interactions between extensional structures and partial melting. In the Golfe du Morbihan, the South Brittany Migmatite Belt (SBMB), tectonically overlain by non‐melted metamorphic units, was studied by combined structural...
