- Abstract
The article "U-Pb LA-ICP-MS age in zircons from the sandstones of the San José Formation in Ciudad de Piedra and Mesoproterozoic gneisses in Guaviare, Colombia" by Franco et al. (2022) contributes to the knowledge of geological events in the Amazonian Craton. It describes the presence of karst phenomena in the sandstones of the San José Formation and the presence of detrital zircons from the Proterozoic basement with ages between 1000 and 1800 Ma. However, some ambiguities in the interpretation of the ages obtained in nearby rocks are pointed out, and the lack of citation of other relevant articles on syenites in the region is mentioned.
