The Atlas-Meseta intracontinental orographic system of Morocco experienced recent, large-scale surface uplift as documented by elevated late Miocene, shallow-water marine deposits exposed in the Middle Atlas Mountains. Anti-Atlas Mountains do not present any stratigraphic records that document regional vertical movements, however, presence a high-standing, erosional surface, and transient state...

[1] The role of channel width and slope adjustments to differential uplift in rivers within actively deforming terrains remains contentious. Here high-resolution topographic surveying of formerly antecedent outwash channels demonstrates marked changes in channel width as a primary response to differential uplift. For five Late Quaternary alluvial paleochannels crossing small folds along the act...

Topographic change in regions of active deformation is a function of rates of uplift and denudation. The rate of topographic development and change of an actively uplifting mountain range, the Santa Monica Mountains, southern California, was assessed using landscape attributes of the present topography, uplift rates and denudation rates. Landscape features were characterized through analysis of...

Companies tend to produce over optimistic forecasts of demand. Psychologists have suggested that optimism, at least in part, results from selective bias in processing information. When high demand is more desirable than low demand information favouring high demand may carry more weight than information that suggests the opposite. To test this, participants in an experiment used a prototypical f...

The Southern Oklahoma Aulacogen (SOA) is a northwest-trending failed arm of a Cambrian triple junction. Significant structures along the SOA include the Wichita Uplift and the Anadarko Basin in southwest Oklahoma. The rift underwent a complex geologic history of bimodal volcanism, faulting, and subsidence before Pennsylvanian compression inverted and uplifted the structure as part of the format...

L. Fengquan 7 B. Jianmin College of Environment and Construction Engineering Changchun University of Science and Technology, Changchun City. 130026. P.R. China Abstract The Qinghai–Tibet Plateau uplifted 13000 m in the Quaternary period. The average rate of uplift was 1–1.1 mm/year. The uplifting has remolded the geomorphology of China. The landform in China was changed from west-low and east-h...

In order to determine the pattern and timing of exhumation and uplift in the Teton Range, fission-track analysis of apatites has been applied to three sections encompassing ~ 2 km of vertical relief along the Teton escarpment. The resulting data provide new insights on the doming of the Precambrian-Cambrian unconformity and on the Teton exhumation/uplift history prior to the Miocene initiation ...

[1] Fold topography preserves a potentially accessible record of the structure and evolution of an underlying thrust fault system, provided we understand the factors that shape that topography. Here we examine the morphology and fault geometry of two active folds at the northwest Himalayan front. The Chandigarh and Mohand anticlines show the following patterns: (1) most (∼60%–70%) growth in cat...
