Resumen:
A high-resolution seismic survey was performed on the Lagoa dos Patos, southern Brazil. The survey was conducted
aboard the research vessel LARUS of the Fundação Universidade Federal do Rio Grande. The seismic profiles were obtained
using a 3.5 kilohertz frequency, which provided a rather good penetration depth and resolution of the records. Results of the
seismic records allowed the determination and mapping of seismic facies and seismic sequences, as well as related architectural
elements, which were identified basically through the configuration patterns of the seismic reflectors. The analysis of the seismic
records allowed the identification of the architectural elements that build up the sedimentary pile accumulated in the coastal
prism of the State of Rio Grande do Sul, contributing to a better understanding of the geological evolution of the southern
Brazilian coastal plain during the Quaternary period.
