A large scale experimental program using vertical and batter model piles in sand subjected to pull out loads has been carried out in a model tank of size 1m x 1m x 1m. Mild steel pipes of varying diameters, lengths, and shapes are used as model piles. A poorly graded river sand having specific gravity G= 2.67, Uniformity coefficient= 3.53, emax = 0.81, emin = 0.54 has been used as foundation me...

[1] Floor-Fractured Craters (FFCs) are a class of lunar craters characterized by anomalously shallow floors cut by radial, concentric, and/or polygonal fractures; additional interior features are moats, ridges, and patches of mare material. Two formation mechanisms have been hypothesized—floor uplift in response to shallow magmatic intrusion and sill formation, and floor shallowing in response ...

The Lower Cretaceous Cedar Mountain Formation of Eastern Utah: a Comparison with the Coeval Burro Canyon Formation, Including New Measured Sections on the Uncompahgre Uplift

Glacial isostatic adjustment explains topographic change in formerly and currently glaciated regions, but the role of small (?100s km) regions unusually low-viscosity mantle is poorly understood. We developed viscoelastic models with upper mantle, measured effect these on solid earth uplift resulting from contemporary surface ice melt. found viscous occurring decadal timescales above region, at...

Thermomechanical models of mantle lithosphere removal from beneath the southern Sierra Nevada region, California (USA), predict a complex spatiotemporal pattern of vertical surface displacements. We evaluate these models by using (U-Th)/He thermochronometry, together with other paleothermometry estimates, to investigate such topographic transients. We target Tertiary strata from the Kern arch, ...

4 He/ 3 He apatite thermochronometry and the 13 C-18 O carbonate paleothermometry

We examine the tectonic geomorphology of La Sila, Calabria, southern Italy, a high-standing (1500 m) plateau surrounded by crustal extension, with map, DEM, and field data. These data are used to constrain a simple geodynamic model that describes short-wavelength deformation of the plateau rim. Topographic metrics including drainage patterns, river longitudinal profiles, and swath profiles are ...

[1] Fold deformation in three dimensions involves shortening, uplift, and lateral growth. Fluvial terraces represent strain markers that have been widely applied to constrain a fold’s shortening and uplift. For the lateral growth, however, the utility of fluvial terraces has been commonly ignored. Situated along northern margin of Chinese Pamir, the Mushi anticline preserves, along its northern...

Low groundwater flow is essential in impeding radionuclide migration the geological disposal of high-level radioactive waste (HLW). In deep subsurface thick marine sediments, may actually be ancient seawater altered during deposition and burial, termed “fossil seawater” this study. such cases, extremely slow because it not affected by infiltration meteoric water, even after uplift erosion strat...
