Controls of erosional denudation in the orogen on foreland basin evolution: the Oligocene central Swiss Molasse Basin as an example
Article Abstract:
A high-resolution three-dimensional reconstruction of the architecture and the deflection of the 25-million-year-old central Swiss Molasse Basin in central Switzerland was performed to demonstrate the importance of sediment supply as a control on the geometrical and stratigraphical evolution. A collection of published chronological and stratigraphical data and sedimentological and petrographical studies were used in the reconstruction. The combination of deflections due to the orogenic load and due to the load of the basin fill was proposed to account for the deflection of the Swiss basin.

Lower paleozoic relative motion of the Arequipa Block and Gondwana; paleomagnetic evidence from Sierra de Almeida of northern Chile
Article Abstract:
Paleomagnetic data show that during the lower Paleozoic the Gondwana supercontinent moved rapidly northward. Consequently, the Arequipa microplate rotated in a pivotal manner away from the Brazilian and Paraguayan shield areas. In the Silurian, the extensional convergent margin shifted to a compressional one, and this shift caused Gondwana to change its 12 cm per year polar drift to a ten cm per year equatorial drift.

Extension and basin formation in the southern Andes caused by increased convergence rate: a mid-Cenozoic trigger for the Andes
Article Abstract:
Research into the complex basins found in the southern Andes between 33 deg and 45 deg S latitude is presented. It is suggested that the surge in significance of crustal shortening in the Andean orogenic history was sparked off by two linked features. Initially, the rise in convergence rate sparked off lithosphere extension while transient instabilities of the subducting plate continued.
