“…In fact, despite a similar lithological composition (Fig. 6c) and a pre-Alpine common geological history (Alvarez and Shimabukuro, 2009), CPA and SB are characterized by a very different density of polygons (0.3 polygons per squared kilometre for CPA and 1.3 for SB) due to strong differences in drafting geological sheets published almost 100 years apart from each other.…”

Abstract. Lithological maps contain information about the different lithotypes cropping out in an area. At variance with geological maps, portraying geological formations, lithological maps may differ as a function of their purpose. Here, we describe the preparation of a lithological map of Italy at the 1:100 000 scale, obtained from classification of a comprehensive digital database and aimed at describing geomechanical properties. We first obtained the full database, containing about 300 000 georeferenced polygons, from the Italian Geological Survey. We grouped polygons according to a lithological classification by expert analysis of the 5456 original unique descriptions of polygons, following compositional and geomechanical criteria. The procedure resulted in a lithological map with a legend including 19 classes, and it is linked to a database allowing ready interpretation of the classes in geomechanical properties and is amenable to further improvement. The map is mainly intended for statistical and physically based modelling of slope stability assessment and geomorphological and geohydrological modelling. Other possible applications include geoenvironmental studies, evaluation of river chemical composition, and estimation of raw material resources. The dataset is publicly available at https://doi.org/10.1594/PANGAEA.935673 (Bucci et al., 2021).

“…While it is not clear whether the publication year of the geological sheets plays or not a role in controlling the polygon density in the Alpine regions, the impact of the different years of publications in the representation of the regional lithological variability is dramatic comparing CPA and SB. In fact, despite a similar lithological composition (Figure 6c) and a pre-Alpine common geological history (Alvarez and Shimabukuro, 2009), CPA and SB are characterized by a very different density of polygons (0,3 polygons/km2 for CPA, and 1,3 for SB), due to strong differences in drafting geological sheets published almost 100 years apart from each other.…”

Abstract. Lithological maps contain information about the different lithotypes cropping out in an area. At variance with geological maps, portraying geologic formations, lithological maps may differ as a function of their purpose. Here, we describe the preparation of a lithological map of Italy at a scale of 1:100,000, obtained from classification of a comprehensive digital database and aimed at describing geo-mechanical properties. We first obtained the full database, containing about 300,000 geo-referenced polygons, from the Italian geological survey. We grouped polygons according to a lithological classification by expert analysis of the original 5,456 unique descriptions of polygons, following compositional and geo-mechanical criteria. The procedure resulted in a lithological map with a legend including 19 classes, and it is linked to a database allowing ready interpretation of the classes in geo-mechanical properties, and amenable to further improvement. The map is mainly intended for statistical and physically based modelling of slope stability assessment, geo-morphological and geo-hydrological modelling. Other possible applications include geo-environmental studies, evaluation of river chemical composition, estimation of raw material resources.

Since the 1960s, the Tyrrhenian Sea rift system has been the target of several geophysical and geological investigations and surveys (DSDP and ODP drilling projects in the bathyal basins) that focused on the nature of the crust (continental vs. oceanic), timing of rifting and direction of extension, faulting style (symmetrical vs. asymmetrical) (Alvarez & Shimabukuro, 2009; Florio et al, 2011; Kastens & Mascle, 1990; Lymer et al, 2018; Malinverno & Ryan, 1986; Mascle & Rehault, 1990; Milia, Iannace, et al, 2017; Milia & Torrente, 2014, 2015a, 2015b, 2018, 2022; Milia et al, 2013; Milia, Torrente, & Tesauro, 2017; Milia, Valente, et al, 2017; Nicolosi et al, 2006; Prada et al, 2014; Sartori, 1990; Sartori et al, 2001).…”

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.
