Subsurface data from the Chacopampean plain, North Argentina

Understanding the evolution of foreland basins provides rich information about present and past orogenies and plate-scale tectonic processes. The Andean foreland basin, also known as the Chacopampean plain, preserves sedimentary records in the subsoil from the late Precambrian to the present day. This region was considered poor in tectonic activity before the Cenozoic. This dataset contributes to the elucidation of the geological evolution of the transitional zone between three distinct basin systems: the Salta Rift, the intracratonic Chacoparanaense, and the Andean foreland basins.
The database consists of 19 seismic lines and data from 18 wells located in the Chacopampean plain, both in the domains of the Chacoparanaense Basin and in the domain of the Salta Rift Basin, and velocity data from seismic headers that allow the correlation of data from time and depth domains.
With these data, we have interpreted a complex tectonic history persisting to the Palaeogene by analysing industry seismic-reflection data and borehole records. This research provides an unprecedented, detailed investigation of a poorly explored region.
