Thermal Maturation andd Hydrocarbon Generation

Mountain building processes directly influence thee thermal history of sedimentary basins. Thick akumulations of sediment in foreland basins bury source rocks to depths where temperatures are superient for hydrocarbourn generation.

The same faults andd fractures that form traps can also serve as conduits for fluid movement, allowing oil and gas to travel from deeple buried source rocks to shallower conveyirs.
