General context: Shock barometry via petrographic analysis helps to understand cratering mechanics, especially mass movements in the central uplift, including its collapse in the late stage of cratering. Shock pressures recorded in lithologies of the central uplift may exceed 45 GPa, e.g., in the Vorotilovo core drilled into the center of the Puchezh-Katunki structure [1]. In other craters, sho...
Spatial and temporal patterns of exhumation are inextricably linked to patterns of crustal deformation because crustal deformation drives rock uplift. A new interpretation of a segment of the Pacific-North America transpressional plate boundary in southern California is analyzed in the context of crustal shortening, rock uplift, and exhumation. Deformation is partitioned between two structural ...
Following the last glacial maximum (LGM), the demise of continental ice sheets induced crustal rebound in tectonically stable regions of North America and Scandinavia that is still ongoing. Unlike the ice sheets, the Alpine ice cap developed in an orogen where the measured uplift is potentially attributed to tectonic shortening, lithospheric delamination and unloading due to deglaciation and er...
We define uplift and denudation, then review the basic principles underlying the mechanisms for producing uplift, and the methodologies used to quantify the geological timescale denudation history of uplifted regions. Uplift is represents work done against gravity, and does not necessarily lead immediately to rapid denudation. The causes of uplift can be categorised according to the principal d...
The recogmuon and dating of corals that have been killed by tectonic uplift allow us to date paleoseismic uplifts in the Vanuatu island arc. We recognize corals that record paleouplifts by their similarity to those known to have died during contemporary sudden uplifts and date them (1) by counting annual coral growth bands (only if f:rt of the coral is alive at the time of collection) or (2) by...

[1] The response of glaciated landscapes to rapid rock uplift, driven by tectonic convergence, is an important, often neglected, aspect of proposed interactions between plate tectonic processes and climate change. Rivers typically respond to more rapid rock uplift in part through increasing channel gradients. In contrast, the ‘‘glacial buzzsaw’’ hypothesis suggests that glaciers can erode as qu...
[1] Images from satellite interferometric synthetic aperture radar (InSAR) reveal uplift of a broad 10 km by 20 km area in the Three Sisters volcanic center of the central Oregon Cascade Range, 130 km south of Mt. St. Helens. The last eruption in the volcanic center occurred 1500 years ago. Multiple satellite images from 1992 through 2000 indicate that most if not all of 100 mm of observed upli...
