The Andes : Active Subduction Orogeny
Convergent plate margins and subduction zones are first order features shaping the Earth. Convergent continental margins combine the majority of processes that affect the internal architecture thermal and geochemical character of continental lith- phere. In addition, the close relationships between active deformation and uplift, m- matism and associated crustal growth, ore formation, the release of more than 90% of global seismic energy at convergent margins, make these plate boundaries imp- tant natural laboratories where mass and energy flux rates can be studied at various scales. Since the advent of plate tectonic theory, it has been recognized that all of these phenomena are intimately related and often governed by feedback mechanisms. Accordingly, subduction orogeny has become an international, high-priority theme in process-oriented, earth-system analysis.
Superplumes : Beyond Plate Tectonics
Provides a concise overview of our understanding of the entire mantle, its evolution since early differentiation and the consequences of superplumes for earth surface processes. The balanced, international authorship of the 18 contributions has produced a state-of-the-science report on the emerging concept of superplumes and has documented the potential of superplumes to serve as a testable model for future studies.The topic of superplume dynamics has been treated from different angles covering the sub-disciplines of geology, geochemistry, petrology as well as geophysics (including mineral physics, seismic tomography and mantle dynamics). For instance, it is shown how transport of heat via superplumes, huge stable pipes connecting the high-temperature core with the surface land mass, could have caused mass extinctions and drastic environmental change.
Microearthquake Seismology and Seismotectonics of South Asia
This volume comprehensively deals with plate tectonics and seismic waves in general and earthquake monitoring by permanent and temporary networks for active fault mapping, aftershock, swarm and induced seismicity investigations in interplate collision and subduction zones and in intraplate shield region.
Clays
Here is a comprehensive and up to-do-date presentation of the origins, and properties of clay minerals at the Earths surface. Concluding chapters show that clay minerals can form in variety of different environments: meteorites, lavas, subduction zones, among others.
