â¢The TVC document the Pampean flat-slab-related volcanic activity in the broken foreland.â¢The TVC is an calc-alkaline magmatic complex related to Neogene Arc-magmatism.â¢According to geomorphological, lithofacial and structural evidence, the TVC is interpreted as an aborted caldera.â¢Initial doming, explosive eruptions and effusive stage was controlled by Nw-WNW and NW-NNW structures and NNE-oriented foliations.
The Neogene Tiporco Volcanic Complex (TVC) is located in the Sierras Pampeanas of San Luis, Argentina, at the southeast of the Pampean flat-slab segment. Based on the comprehensive study of lithofacies and structures, the reconstruction of the volcanic architecture has been carried out. The TVC has been modeled in three subsequent stages: 1) initial updoming, 2) ignimbritic eruptive activity and 3) lava dome emplacement. Interplay of magma injection and transtensional tectonic deformation has been invoked to reproduce TVC evolution.
