Growth faults have great significance for stratigraphy, structural geology and the petroleum industry. They account for relative and eustatic sea level changes and accommodation space left for new sediments. Likewise, growth faults are connected directly to the subsidence in the coastal and continental shelf areas. Moreover, they explain lateral thickness variation of sedimentary sequences across these faults. The updip area on the downthrown block is the main target of o… WebMar 13, 2024 · Growth faults have two blocks. The upthrown block – the footwall – is landward of the fault plane and the downthrown block – the hanging wall – is basinward of the fault plane. Most deformations occur within the hanging wall side. The downthrown block slips downward and basinward relative to the upthrown block.
