“…Thus, the occurrence of Pliocene should be expected. In neighbouring basins, clay deposits seem to record a steady, although often discontinuous, offshore sedimentation from the Zanclean to the Piacenzian, or more feasibly, to the Calabrian [8][9][10][11][12]45,70,71,89]: the top of the deposits, indeed, records a similar situation such as the one described for Valdichiana.…”

“…The Neogene-Quaternary geological evolution of the wider area between western Umbria, southeastern Tuscany, and northeastern Latium (Figures 1 and 2) appears well outlined, from the onset of a marine basin (the Valdichiana Basin) during the Early Pliocene to the continental-shallow coastal marine phase (Early Pliocene-Early Pleistocene), and finally to the wide continentalization, with volcanic episodes, and the setup of lacustrine basins, from the early-middle Pleistocene onwards, that led to the current river valley setup [1][2][3][4][5][6]. In fact, geological and stratigraphic reconstruction throughout the Pliocene and Pleistocene deposits in western Umbria resumes more than one hundred years of study, and it fits in the comprehensive geological evolution of Neogene extensional basins in northern Apennines [4,[7][8][9][10][11][12].…”

“…[9]): nonetheless, the high local variability indicates that each basin, or macro-area, had its own geological evolution [6,7]. In fact, this evolution results from a complex interaction between extensional and compressional tectonic regimes during the eastward migration of the Apennines, and between tectonics and sea-level change [4,[7][8][9][10][11][12].…”

Through time, the wide area between southeastern Tuscany, northeastern Latium, and western Umbria has been revealed as a crucial area for understanding the evolution of Neogene basins in northern Apennine. In this study, the results of twenty years of research on the marine early Pleistocene deposits are summarized, and the biological and physical events are presented and discussed in order to propose an integrated stratigraphic scheme. The proposed reconstruction is also included in a wider context, taking into account both the local and regional geological evolution.

“…In southern Tuscany these are, from top to bottom ( Figure 2): (a) the Ligurian and Sub-Ligurian Units, consisting of remnants of Jurassic oceanic and transitional crust and their related Cretaceous-Oligocene sedimentary cover; (b) the Tuscan Units including the Triassic-early Miocene sedimentary (Tuscan Nappe) and Palaeozoic-Triassic metamorphic succession. According to [29,30], this metamorphic succession can be broadly subdivided in (i) a late Cambrian?-Mississippian basement (affected by deformation during the Variscan orogenesis) and (ii) a Late Pennsylvanian to Triassic sedimentary cover, deposited during the Variscan post-collisional events. Figure 2.…”

Reconsidering the Variscan Basement of Southern Tuscany (Inner Northern Apennines)

The Pre-Mesozoic units exposed in the inner Northern Apennines mostly consist of Pennsylvanian-Permian successions unconformably deposited on a continental crust consolidated at the end of the Variscan orogenic cycle (Silurian-Carboniferous). In the inner Northern Apennines, exposures of this continental crust, Cambrian?-Devonian in age, have been described in Northern Tuscany, Elba Island (Tuscan Archipelago) and, partly, in scattered and isolated outcrops of southern Tuscany. This paper reappraises the most significant succession (i.e., Risanguigno Formation) exposed in southern Tuscany and considered by most authors as part of the Variscan Basement. New stratigraphic and structural studies, coupled with analyses of the organic matter content, allow us to refine the age of the Risanguigno Fm and its geological setting and evolution. Based on the low diversification of palynoflora, the content of sporomorphs, the structural setting and the new field study, this formation is dated as late Tournaisian to Visean (Middle Mississippian) and is not affected by pre-Alpine deformation. This conclusion, together with the already existing data, clearly indicate that no exposures of rocks involved in the Variscan orogenesis occur in southern Tuscany.

“…The mean annual air temperature is 11.3 • C; July and August are the warmest months and January is the coldest. The IR farm is situated on deposits formed after multiple landslides in the surrounding mountains, where there is a marly-shaly-sandstone sedimentary succession of the early Miocene age outcrops [25,26] (Figure 1b). The IR farm specializes in the production of small fruits, in particular raspberries.…”

Soil Carbon Investigation in Three Pedoclimatic and Agronomic Settings of Northern Italy

et al. 2020

Sustainable agricultural management is needed to promote carbon (C) sequestration in soil, prevent loss of soil fertility, and reduce the release of greenhouse gases. However, the influence of agronomic practices on soil C sequestration depends on the existing pedoclimatic features. We characterized the soils of three farms far away each other in the Emilia-Romagna region (Northern Italy): an organic farm in the Northern Apennines, a biodynamic farm, and a conventional farm on the Po Plain. The total, inorganic, and organic carbon in soil, as well as the distinct humic fractions were investigated, analyzing both the elemental and isotopic (13C/12C) composition. In soils, organic matter appears to be variously affected by mineralization processes induced by microorganisms that consume organic carbon. In particular, organic carbon declined in farms located in the plain (e.g., organic carbon down to 0.75 wt%; carbon stock0-30 cm down to 33 Mg/ha), because of the warmer climate and moderately alkaline environment that enhance soil microbial activity. On the other hand, at the mountain farm, the minimum soil disturbance, the cold climate, and the neutral conditions favored soil C sequestration (organic carbon up to 4.42 wt%; carbon stock0-30 cm up to 160 Mg/ha) in humified organic compounds with long turnover, which can limit greenhouse gas emissions into the atmosphere. This work shows the need for thorough soil investigations, to propose tailored best-practices that can reconcile productivity and soil sustainability.
