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...

S U M M A R Y Extreme uplift rates and sea level changes in southern Alaska have been documented by Global Positioning System (GPS) surveys, tide gauge measurements and studies of raised shorelines. The movements detected in a network of 45 GPS survey points describe a broad pattern of rapid regional uplift. The majority of the study area is uplifting at a rate faster than 10 mm yr−1, with seve...

Wind dynamics, on a conventional roofing system, lift the membrane and cause fluttering, introducing stresses at the attachment locations. To identify the component of the system that has the weakest resistance against wind uplift forces, a dynamic method of evaluating roofing systems is beneficial. A recent industry survey predicts significant growth for thermoplastic polyolefin ~TPO! membrane...

[1] Large uplifts and tilts occurred on the Sumatran outer arc islands between 0.5 and 3.3 S during great historical earthquakes in 1797 and 1833, as judged from relative sea level changes recorded by annually banded coral heads. Coral data for these two earthquakes are most complete along a 160-km length of the Mentawai islands between 3.2 and 2 S. Uplift there was as great as 0.8 m in 1797 an...

Recent phylogenetic studies have revealed the major role played by the uplift of the Andes in the extraordinary diversification of the Neotropical flora. These studies, however, have typically considered the Andean uplift as a single, time-limited event fostering the evolution of highland elements. This contrasts with geological reconstructions indicating that the uplift occurred in discrete pe...

In their Comment, Zeitler et al. do not challenge our results or interpretation. Our study does not disprove coupling between tectonic uplift and erosion but suggests that this coupling cannot be the sole explanation of rapid uplift in the Himalayan syntaxes.

Conventional wisdom holds that the southern Appalachian Mountains have not experienced a significant phase of tectonic forcing for >200 myr; yet, they share many characteristics with tectonically active settings, including locally high topographic relief, steep slopes, incised river gorges, and frequent mass-wasting events. Two competing hypotheses are commonly used to explain their modern topo...

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...
