Looking at fault reactivation matching structural geology and seismological data

Journal of Structural Geology, 2005
Abstract We investigate fault reactivation that occurred during the 1997 Colfiorito seismic sequence (central Italy), matching detailed structural geology, precise earthquake locations and mechanical models of fault interaction. The Colfiorito area, within the Northern Apennines, is characterised by a relatively recent inversion of the tectonic ...

Geology of the Thrust Fault near Gardiner, Montana

The Journal of Geology, 1934
The Gardiner thrust fault has been mapped in detail from the west side of Cinnabar Mountain, Montana, where it appears from under a cover of Tertiary volcanics, southeastward to a point 3 miles east of Mount Everts, Yellowstone National Park, where it passes under the volcanics.

Structural Geology of Shawneetown Fault Zone, Southeastern Illinois: ABSTRACT

AAPG Bulletin, 1983
Vertical movements of crustal blocks along the narrow east-west-trending Shawneetown fault zone in southeastern Illinois occurred between Early Permian and Late Cretaceous. The main blocks moved vertically and returned to roughly their original positions so that strata now show little relative offset across the fault zone.

Polygonal faulting in the Tertiary of the central North Sea: implications for reservoir geology [PDF]

Geological Society, London, Special Publications, 1998
Abstract Interpretation of regional two-dimensional seismic surveys and three-dimensional seismic surveys in the central North Sea has demonstrated the existence of a pervasive polygonal network of normal faults affecting Tertiary shale-dominated slope and basin-floor depositional systems.

Contributions to the Geology of the Mere Fault and the Vale of Wardour Anticline

Proceedings of the Geologists' Association, 1961
Abstract Detailed mapping of the western end of the northern limb of the asymmetrical Tertiary Wardour Anticline around East Knoyle and the Mere Fault from West Knoyle to Bayford, a distance of nine miles, is described. The Mere Fault downthrows north bringing Jurassic rocks on the upthrown side against Cretaceous Beds on the downthrown side.

From geology to seismic parameters in slow faults: new challenges

2021
Paleoseismology allows the characterization of seismogenic faults in high strain rates regions but also in areas with moderate rates of deformation like the Iberian Peninsula. There, an important amount of paleoseismic information has been obtained that have allowed the detection of a number of seismic sources and to estimate their seismic potential by

The Geology of a Portion of the Redlands Quadrangle, California : a Study in Faulting

1931
The San Andreas Rift after passing through the Cajon Pass in Southern California proceeds approximately S 60° E along the base of the San Bernardino Mountains which rise to the north. About eight miles east of the city of Redlands, Mill Creek issues from the San Bernardino Mountains south-west on to the alluvium covered flood plain. Four miles to the

Frictional-viscous flow, seismicity and the geology of weak faults: a review and future directions

Geological Society, London, Special Publications, 2008
Abstract Previously hypothesized fault weakening mechanisms include faults lined by low-friction clay gouges, elevated pore pressures within fault cores and/or the operation of dynamic weakening during seismic slip. Geological studies to support dynamic weakening are still in their infancy and there is little geological evidence for the ...
