Deep seismic reprocessing of industrial lines, combined with surface geologic and structural data, provides the basis of a new tectonic interpretation of the northern Sierras Pampeanas at 27°S latitude. These basement mountain blocks, uplifted during an episode of shallowing of the subduction zone, show an active double-wedge thrusting. Deep seismic data indicate the different vergences of the western and eastern sectors of the Sierra de Aconquija, in the western Sierras Pampeanas at this latitude. Neotectonic evidence reveals that both systems are active, although the western sector has been active since at least middle to late Miocene times and recorded...

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.
