Evolution of continental crust in the Proterozoic : growth and reworking in orogenic systems
… on three different Palaeo- to Meso-Proterozoic orogenic belts; in Fennoscandia, in North American Grenville and in the Birimian terrane of the West African craton. The eastern part of the Sveconorwegian Province, located in the southwestern part of the Fennoscandian Shield, is made up of …

The thermal and metamorphic evolution of the Northern Highlands Terrane, Scotland
… and convergent deformation related to several orogenic events that occurred from Neoproterozoic to Devonian time. Deconvolving the signatures of multiple tectonic events and determining the rates of metamorphism in settings like the NHT are important parts of better understanding the thermal …

Thermo-tectonic record of hyperextension, structural inversion, and foreland basin evolution of the eastern and central Pyrenees
… and structural evolution of continental rift systems, and the role of pre-existing crustal architecture on orogenesis and foreland basin development. This work constrains the Early Cretaceous hyperextension history along the Iberia-European margin and how rift inheritance affected the …

A Thermochronological Investigation of Orogenic Architecture, Kinematics, and Tectonic-Climatic Interactions within the St. Elias Orogen, Alaska
The kinematics and architecture of orogenic systems may be heavily influenced by climate, but little research has focused on the long-term effects of glacial erosion on orogenesis. Low-temperature thermochronometry and subsidiary structural, earthquake relocation, and offshore seismic reflection …

The architecture and evolution of intracontinental orogens: a structural, metamorphic and geochemical characterisation.
… alone. However, the comparative rarity of such orogenic systems in the geological record means that their architecture and evolution are poorly understood. In order to address this deficiency, this thesis presents an integrated framework that characterises the structural, metamorphic and …

Behavior of Hybrid Thick- and Thin-Skinned Orogenic Wedges in the Western Interior USA and South-Central Andes
… convergence and the construction of Cordilleran orogenic systems. These systems are at dramatically different stages in their tectonic evolution, enabling a comparison of the actively forming Andes with their ancient counterpart in North America. Despite this advantageous geologic situation, …

Tectonic and climatic controls on orogenic processes : the Northwest Himalaya, India
… these domes is accommodated by extensional fault systems.Along the Indian-Tibetan border the poorly described Leo Pargil metamorphic-igneous gneiss dome (31-34°N/77-78°E) is located within the Tethyan Himalaya. New field mapping, structural, and geochronologic data document that the western flank …

Tectonics and kinematics of curved mountain belts: examples from the Andes and the Alps
… mechanisms of formation. The need of studying orogenic bends arises from the numerous questions to which geologists and geophysicists have tried to answer to during the last two decades, such as: what are the mechanisms governing orogenic bends formation? Why do they form? Do they develop in …
