The technique developed by Watts & Ryan in 1976 allows for the recovery of the basement subsidence and uplift history in the absence of sediment and water loading and, therefore isolate the contribution from the tectonic forces responsible for the formation of a rift basin.

The Late Paleocene to the Early Eocene ( 55 Ma ) saw rift basin formation in the Fuegan Andes which led to crustal extension : the first sign of separation between the two continents and the formation of the South Scotia Sea and South Scotia Ridge.

The coal from this small pit was used to fuel his blacksmith shop on the same property . " Farmville has coal deposits because it sits on the Farmville Basin, one of the Eastern North America Rift Basins west of modern day, Virginia State Route 45.

The basin originated as a rift basin in the context of extensional tectonics and crustal thinning that followed the Paleozoic Gondwanide orogeny . { { refn | name = note 1 | group = note | These tectonics are not related to the break-up of Gondwana later in the Mesozoic.

The Gulf is underlain by the Gulf of California Rift Zone, a series of rift basins and transform fault segments between the northern end of the East Pacific Rise in the mouth of the gulf to the San Andreas Fault system in the vicinity of the Salton Trough rift / Brawley seismic zone.

As the Jeanne d'Arc rift basin subsided, it was gradually in-filled with sediments eroded from adjacent areas of crustal uplift . Characteristics of the sedimentary basin fill and their relationships to the extensional history of the Jeanne d'Arc Basin have been variably described by numerous authors with general agreement on the applicability of rift concepts to the basin.

The "'Niger Delta Basin "', also referred to as the "'Niger Delta province "', is an extensional rift basin located in the Niger Delta and the Gulf of Guinea on the passive continental margin near the western coast of Nigeria with suspected or proven access to Cameroon, Equatorial Guinea and S�o Tom?and Pr�ncipe.

The Ramapo Fault, which marks the western boundary of the Newark rift basin, has been argued to be a major seismically active feature of this region, but it is difficult to discern the extent to which the Ramapo fault ( or any other specific mapped fault in the area ) might be any more of a source of future earthquakes than any other parts of the region.
