Recent thrust faulting in southeastern Connecticut

Geology, 1979
Since precolonial times, low-magnitude seismic activity has been noted in southeastern Connecticut. South of Colchester, drill holes made in 1970 for roadcut blasting soon developed offsets that provide evidence for recently active thrust faulting.

Alternative model of thrust-fault propagation

Geology, 1987
A widely accepted explanation for the geometry of thrust faults is that initial failures occur on deeply buried planes of weak rock and that thrust faults propagate toward the surface along a staircase trajectory. We propose an alternative model that applies Gretener's beam-failure mechanism to a multilayered sequence. Invoking compatibility conditions,

Scaling properties of thrust fault traces in the Himalayas and inferences on thrust fault growth

Journal of Structural Geology, 2006
Abstract Map traces of thrust faults in the Himalaya show a conspicuous cuspate–lobate pattern, i.e. broad lobes joined by sharp angular cusps. For each lobe, we can draw a chord by joining the apices of two adjacent cusps, and define amplitude (A) by perpendicular distance of apex of the lobe from its chord.

The Study of the Thrust Fault

Advanced Materials Research, 2014
The thrust fault plays an important role in the migration of oil and gas, etc. It can either block the oil and gas lateral migration, or become a good migration pathway. In order to have a more intuitive observation on forming process and study on the vital influential factors of it, the thick and extrusion stress of layers, such as laboratory with ...

Thrust Faults of Ventura Basin: ABSTRACT

AAPG Bulletin, 1953
When examining the over-all picture of the Ventura basin, one is impressed by the number of large thrust faults which occur. These east-west faults are among the most predominant structural features of the area. Much of the present topography is controlled by these faults. There is good evidence that much of the movement of these faults occurred during

Thrust faults in inverted extensional basins

1992
Thrust faults in inverted extensional basins may not exhibit the simple low-angle, ramp-flat thrust trajectories that are characteristic of many foreland fold and thrust belts, but are expected to show more complex geometries controlled by the architecture of the earlier extensional fault system.

Earth Tides Can Trigger Shallow Thrust Fault Earthquakes

Science, 2004
We show a correlation between the occurrence of shallow thrust earthquakes and the occurrence of the strongest tides. The rate of earthquakes varies from the background rate by a factor of 3 with the tidal stress. The highest correlation is found when we assume a coefficient of friction of μ = 0.4 for the crust, although we see good correlation for μ ...

Sierra Madre thrust fault, Arcadia, California

1987
Abstract One of the best exposures of the Sierra Madre thrust fault can be seen in the west wall of Santa Anita Canyon in Wilderness Park, city of Arcadia, 15 mi (25 km) northeast of downtown Los Angeles. Figure 1 shows how one can drive to the fault exposure by turning left into the first available parking area in Wilderness Park.

Thrust Faulting and Hydrocarbon Generation: DISCUSSION

AAPG Bulletin, 1987
Following the discovery of large volumes of hydrocarbons in the Cordilleran thrust belt of southwestern Wyoming and northern Utah, Angevine and Turcotte (1983), Edman and Surdam (1984), and Furlong and Edman (1984) discussed the role of thrust faulting in hydrocarbon generation.
