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.

Detachment Fault Control on Hydrothermal Circulation Systems: Interpreting the Subsurface Beneath The Tag Hydrothermal Field Using The Isotopic and Geological Evolution of Oceanic Core Complexes in The Atlantic

, 2013
The geology and alteration history of two well-studied and very similar oceanic core complexes (OCCs) along the Mid-Atlantic Ridge are compared: the Atlantis Massif at 30°N (Integrated Ocean Drilling Program Site U1309) and a dome-like massif at 15°45′N (

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

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.

Normal Fault Growth in Three‐Dimensions in Continental and Oceanic Crust

, 2013
In the past, structural geology and mid-ocean ridge research have been divided disciplines; the former relying on field observations from the continents, the latter being based on remote sensing data from the deep-oceans.

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 ...

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
