New Constraints For Convergent Margin Plate Tectonic Reconstructions From Imaged And Predicted Mantle Structure
… margins, where tectonic plates are lost due to subduction. Our aim is to develop new, non-traditional constraints for convergent margin plate reconstructions from imaged and predicted mantle structure using seismic tomography and forward geodynamic models, respectively. We apply …

Volcano-tectonic history and volcanic hazard assessment of the 22.5-29°S segment of the Central Volcanic Zone of the Andes
… response time of ~10-12 Myr is estimated between ridge subduction and the onset of high-flux magmatism at 22.5-24°S (~9 Ma) and 25-26°S (~5.5 Ma). If this trend continues, the 26.5-27.5°S segment, which hosted the Cerro Blanco eruption, is likely to experience a magmatic flare-up in the next few …

Die neogene Hebungsgeschichte der Patagonischen Anden im Kontext der Subduktion eines aktiven Spreizungszentrums
Das Phänomen der Subduktion eines aktiven Spreizungszentrums an der Südspitze Südamerikas ist seit langem bekannt. Eine Vielzahl von geologischen Beobachtungen wurden mit diesem Phänomen in Verbindung gebracht, trotzdem ist der genaue Mechanismus der Beeinflussung des aktiven Kontinentalrandes …

THERMOTECTONIC EVOLUTION OF THE ALASKA RANGE: LOW-TEMPERATURE THERMOCHRONOLOGIC CONSTRAINTS
… margin is a complex boundary defined by active subduction and accretion of numerous terranes including the Yakutat microplate, the formation of a distinct volcanic arc system, and the development of major intracontinental strike-slip fault systems. The Alaska Range is located ~500 km inland of …
