In mountain ranges, neotectonics can be considered as the main factor contributing to tectonic-geomorphological features being the result of the competition between tectonics and erosion. Several tectonic-geomorphological indicators such as drainage basin based (asymmetry factor of drainage basin (Af), hypsometric integral (Hi)) and mountain front...
Inversion tectonics has a major impact on distribution of fault-controlled hydrocarbon traps in the fold-and-thrust belts.
