Exhumation and Basin Development Related to Formation of the Central Andean Plateau, 21° S
Thermochronological (apatite fission track, AFT) and sedimentological data from the central Andean high plateau and its eastern foreland reflect the Tertiary tectonic evolution of this plateau. AFT data define...

Controls on the Deformation of the Central and Southern Andes (10–35° S): Insight from Thin-Sheet Numerical Modeling
What mechanisms and conditions formed the Central Andean orocline and the neighboring Altiplano Plateau? Why does deformation decrease going from the central to the Southern Andes? To answer these questions, w...

Chapter
The Time-Space Distribution of Cenozoic Volcanism in the South-Central Andes: a New Data Compilation and Some Tectonic Implications
The coincidence of late Paleogene to Neogene shortening and crustal thickening with vigorous volcanic activity in the central Andes has long invited speculation about a causal relationship between magmatism an...

Chapter
Oblique Convergence along the Chilean Margin: Partitioning, Margin-Parallel Faulting and Force Interaction at the Plate Interface
The Chilean fore-arc exhibits margin-parallel strike-slip faulting and associated fore-arc sliver formation. Comparison of the long-term (geologic timescale) and short-term (human timescale) record of margin-p...

Chapter
The Salar de Atacama Basin: a Subsiding Block within the Western Edge of the Altiplano-Puna Plateau
The internally drained Salar de Atacama (SdA) Basin, located in the proximal fore-arc between the present magmatic arc (Western Cordillera) to the east and the North Chilean Precordillera (Cordillera de Domeyk...

Chapter
Central and Southern Andean Tectonic Evolution Inferred from Arc Magmatism
Patterns of spatial distribution, and geochemical and isotopic evolution from subduction-related igneous rocks provide tools for scaling, balancing and predicting orogenic processes and mechanisms. We discuss ...

Chapter
Tectonic Development of the North Chilean Andes in Relation to Plate Convergence and Magmatism Since the Jurassic
Since the early Jurassic the magmatic arc of the north Chilean Andes has been displaced from the Coastal Cordillera to the Western Cordillera. This eastward migration happened stepwise and four successive, ± s...
