The mechanics of initiation and development of thrust faults and thrust ramps

Mountain Geologist, 2022
This study integrates the results of numerical modeling analyses based on outcrop studies and structural kinematic restorations to evaluate the mechanics of thrust fault initiation and development in mechanically layered sedimentary rocks. A field-based reconstruction of a mesoscopic thrust fault at Ketobe Knob in central Utah provides evidence of ...

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 ...

Development of Thrust Faults

Geological Society of America Bulletin, 1935
INTRODUCTION The characteristic feature of all faults is displacement. But faults are finite, they must die out downward as well as laterally, and many faults originally failed to reach the surface. Displacement thus becomes zero at the margins of the fault plane, and must, therefore, vary, not only across the direction of movement, but also parallel ...

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.

Faulted craters as indicators for thrust motions on Mercury

Geological Society, London, Special Publications, 2014
Abstract Craters cross-cut by faults are used as markers to obtain fault geometric and kinematic properties. Assuming that the shape of these craters was originally circular, it is possible to measure the horizontal and vertical components of fault displacement as well as the slip trend.

Thermal effects of thrust faulting

Earth and Planetary Science Letters, 1981
Abstract Calculations based on simple models of overthrust sheets in crystalline basement rocks show that significant thermal effects may result from their movements. If rates are sufficiently high (e.g. plate tectonic rates), the thrust sheets sufficiently thick (5, 10 and 15 km are modelled here), the distances moved sufficiently large, and for ...

The Pamir frontal thrust fault

2021
The Pamir Frontal Thrust (PFT) of the Trans-Alai Range in Central Asia is the principal active fault of the intracontinental convergence zone between the Pamir and Tien Shan. Its northward propagation is reflected by frequent seismic activity and ongoing crustal shortening.

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.

The Saltville thrust: investigation of a regional thrust fault in a foreland fold and thrust belt

2020
Thin-skinned models of deformation are currently accepted for the southern Appalachians. The mechanics of this type of deformation are not well understood. The Saltville thrust, a major overthrust in the southern Appalachians, was investigated with respect to deformation mechanics.

Folded thrust faults in the foothills of Alberta

Geological Society of America Bulletin, 1942
This paper describes the stratigraphic and geologic structure of an area in the Rocky Mountain foothills of west-central Alberta. An unusual group of low-angle thrust faults is described and analyzed. At least seven overlapping faults were recognized which range up to 30 miles in length and have an aggregate displacement of about 6 miles.
