[1] The reason for the survival of mountainous topography in ancient orogenic belts is a long-standing problem in geomorphology and geodynamics. We explore the geomorphologic controls on the timescale for the postorogenic decay of topography to address the question of whether there is a viable geomorphologic explanation for the persistence of topography in ancient orogenic belts or whether alte...

The Dobroe deposit with 10 t gold reserves is one of the mines located within Yenisei Ridge Orogenic Belt. ore-forming conditions orogenic deposits are have recently been widely discussed. A comprehensive study fluid inclusions revealed that was formed by water–carbon dioxide and carbon dioxide–hydrocarbon fluids a temperature range 180 to 360 °C, pressure 0.8 1.3 kbar, salinity 1.5 15.0 wt.% (...

between the lower and upper cretaceous there were some diastrophic movements, belonging to the austrain phase. these movements, which can be traced in many parts of north and central iran, caused extensive precenomanian erosion. even in southwest iran a wide spread discontinuity is reported at the base of the kazhdumi formation, which is possibly related to these movements. in the kopet - dagh ...

In convergent systems, the interplay between tectonics, erosion, and sedimentation controls orogenic evolution. The nature of interactions these factors is still elusive due to complex feedbacks that operate across different temporal spatial scales. Here, we investigate with analog models landscape evolution designed account for both tectonic forcing surface processes, using a water-saturated g...

The 500,000 km Saharan Metacraton in northern Africa (metacraton refers to a craton that has been mobilized during an orogenic event but that is still recognisable through its rheological, geochronological and isotopic characteristics) is an Archean–Paleoproterozoic cratonic lithosphere that has been destabilized during the Neoproterozoic. It extends from the Arabian–Nubian Shield in the east t...
