Geochronologic, structural, and metamorphic data obtained from the hinter-land of the Canadian Cordillera indicate that middle-crust ductile deformation was diachronous and coincided temporally with thrust propagation in the Rocky Mountain Thrust-and-fold Belt. Rocks currently at the highest structural level were deeply buried and then exhumed to upper-crust levels during the Middle Jurassic, when the orogenic wedge was in its early stages of evolution. However, structurally deeper rocks were buried and then exhumed at progressively more recent times, such that the deepest exposed level was not buried until the Eocene. This late stage of burial coincided with the final stages...

Thrust Tectonics and Hydrocarbon Systems
Thrust Tectonics and Hydrocarbon Systems resulted from an international conference at Royal Holloway University in London. The volume contains 33 chapters divided into four sections:Geodynamics of Thrust Systems, Analog Modeling of Thrust Systems, Fault-Related Folds in Thrust Systems,and Case Studies. These papers summarize recent advances in thrust studies and their application to hydrocarbon exploration and production.Key topics addressed include the application of the critically tapered Coulomb wedge model to thrust systems both in nature and in experiments, the interaction of surface proceses with thrust systems, basement-involved thrust systems and inversion, fault-related folds in thrust belts, and growth stratal development in thrust belts. Fold-and thrust belts described and discussed in this volume include the Alps, the Andes, the Apennines, the Appalacians, the Alice Springs Orogen in Australia, the Albanides, the Atlas in Morocco, the Canadian Cordillera and the Canadian Rocky Mountains, Kutei Basin, Kalimantan, the Himalayas, the New England Orogen, Papua New Guinea, and the Spanish Pyrenees, as well as depwater fold and thrust belts such as the Niger Delta and the Gulf of Mexico. Memoir 82 provides an in-depth look at thrust tectonics and hydrocarbon systems, and is a milestone publication as a major new examination of thrust fault systems.
