Impact of volcanism on the sedimentary record of the Neuquén rift basin, Argentina: towards a cause and effect model [PDF]

open access: yes, 2018
The analysis of volcano-sedimentary infill in sedimentary basins constitutes a challenge for basin analysis and hydrocarbon exploration worldwide. In order to understand the contribution of volcanism to the sedimentary record in rift basins, we study the
