... paleomagnetic data from the latest Cretaceous Whitehorn Granodiorite is presented to assess the effect of possible upper crustal tilting on these transects. These data, in combination with new zircon (U-Th)/He thermochronometry and 40 Ar/ 39 Ar and zircon U-Th-Pb geochronology from the Whitehorn Granodiorite...

... of lake shorelines and rivers, and lava flow morphology to constrain the spatial and temporal evolution of magmatism at Uturuncu and Lazufre. Near Uturuncu, dated lake shorelines show no evidence of tilting since ca. 16 ka, and we find no evidence of deformation in the long-wavelength topography. A lack...

... José), and 46.1° ± 5.9° and −31.0° ± 7.0° (El Potrero). The discordance is best explained by west-down tilt of the crustal block between the Main Mártir thrust and the Rosarito fault, which are major compressional structures parallel to the trend of the Peninsular Ranges. The San Pedro Mártir pluton...

... an alternative to the previously published model that the Gold Butte block is a tilted 15–18-km-thick intact basement crustal section. Mapping of windows of crystalline basement at 1:12,000 scale delineates a bedding-parallel detachment fault system that parallels the Great Unconformity in the Tramp Ridge block...

.... The source for the landslides and debris avalanche deposits is unknown, but it was probably an adjacent scarp along a transverse fault bounding an early part of the Mormon dome. An average 45° of easterly tilt of the entire Tertiary basin-fill succession represents the major post–14 Ma deformation event...

... at mid-crustal depths. The eastern Transverse Ranges thus constitute a tilted, nearly continuously exposed crustal section of the Mesozoic magmatic arc and framework rocks from subvolcanic levels to paleodepths as great as ~22 km. The base of this tilted arc section is a moderately east-dipping sheeted...

... of this subcontinental-scale erosional episode. However, the lack of a well-defined Cenozoic paleoelevation history for the region has hampered our ability to distinguish between the two. A tilt analysis of the Cheyenne Tablelands in the western Great Plains of Wyoming and Nebraska provides us with a datum from which...

The process of toe-cutting can lead to complete fan destruction and may be a response to climate change, tectonic tilting, fault propagation or a combination of these variables. It gives rise to: near horizontal...

Careful chemical studies of both minerals confirm the role of Mg as a minor but essential constituent in the todorokite structure...

...-arc construction. Although tight folds can account for such steep bedding tilts, folds in the metavolcanogenic sections are sparse and small scale. We propose that the high bedding tilts were produced by a combination of thrusting, downward displacement, and ductile deformation of the beds. The last...
