Regional Deformation and Dynamic Processes of the Southern Puna Plateau, Central Andes
The southern Puna Plateau of the central Andes offers an excellent opportunity to (1) advance our understanding in orogenic models for non-collisional mountain belts, (2) test Earth’s upper-crustal responses to lower lithospheric processes, and (3) explore uses of low-temperature thermochronology …

Origin and evolution of parental magmas associated with Pliocene-Quaternary low-silica volcanism within the Altiplano-Puna Volcanic Complex of northern Chile
… marginal to the partially molten Altiplano-Puna Magma Body (APMB) in the Altiplano-Puna Volcanic Complex of northern Chile, between 21º10'S and 22º50'S. To unravel the petrogenesis of these less evolved eruptives and their spatiotemporal assessment, this work makes use of new major and trace …

The petrogenesis of the Pliocene Araral stratovolcano in the Andean Central Volcanic Zone, Northern Chile
The Altiplano-Puna Volcanic Complex (APVC) is a silicic volcanic complex in the Central Andean Volcanic Zone (CVZ). The APVC is underlain by the thickest known crust in a continental arc setting and the largest known magma body – the Altiplano-Puna Magma Body (APMB). Lavas of the APVC and CVZ are …

Tectonics and kinematics of curved mountain belts: examples from the Andes and the Alps
… Cordillera at the border with the Altiplano-Puna plateau induced up to ~40° counterclockwise rotations along the fault zone, locally annulling the regional clockwise rotation. We proposed that mid-Miocene strike-slip activity developed in response of a compressive stress (related to body …

Examining the Impact of social media engagement on students’ motivation in MOOCs
The rapid development of Massive Online Open Courses (MOOCs) has attracted significant attention. Despite the publicity, one of the major problems is the high dropout of MOOC learners. Many MOOCs attract thousands of learners; thus, it is inevitable that they will have diverse motivations for …
