Comment on Loreto et al., 2021: Extensional tectonics during the Tyrrhenian back-arc basin formation and a new morpho-tectonic map

The recent article of Loreto et al. (2021) reported new stratigraphic and structural data of the Tyrrhenian backarc basin and used them to propose a new model of crustal architecture of the basin including oceanic sectors. However, we want to open a discussion on the inconsistencies between the interpreted tectonic structures, as well as the age of faults and the data observations. In particular, data analyses and interpretations of the authors do not fully support the structural and isopach maps and models presented. Furthermore, the authors have not discussed previous published data/interpretations on timing and structural style of the rifting of the region.

Automated summary

The recent article by Loreto et al. (2021) presents a new model of crustal architecture for the Tyrrhenian backarc basin based on new stratigraphic and structural data. However, there are inconsistencies in the interpreted tectonic structures, the age of faults, and the data observations. The authors' analyses and interpretations do not fully support the presented structural and isopach maps and models. Additionally, the authors have not discussed previously published data/interpretations on the timing and structural style of the regional rifting.
