“…This result is comparable to the cumulic soil described at the top of the Val Sorda loess sequence [ Cremaschi et al ., ; Ferraro , ], not far from Monte Netto. The dating CAP03 indicates a period almost contemporaneous with dust sedimentation recorded in other loess sequences along the northern margin of the Po Plain Loess Basin [ Cremaschi and Lanzinger , ; Cremaschi et al ., ; Ferraro , ; Wacha et al ., ; Cremaschi et al ., ]. Samples CAP01 and CAP02 gave Holocene ages for the upper part of the sequence (7483–7287 and 5574–5094 cal years B.P.).…”

Here we present, for the first time in the Po Plain foredeep (Northern Italy), the middle to late Pleistocene growth history of an outcropping secondary fold and related faults, whose progressive deformation over an intermediate time window (10 5 years) is driven by an underlying seismogenic blind thrust. We trenched and logged an outcropping decametric secondary anticline, related to a deeper blind compressional structure, which deforms fluvial sediments and an overlying loess-paleosol sequence. Folded units were dated, using radiocarbon and optically stimulated luminescence methods, to the late Pleistocene-Holocene and tentatively correlated with glacial-interglacial phases occurring during the time interval from marine isotope stage 6 to the present. A multistep retrodeformation of the fold allowed us to calculate uplift rates for this secondary and shallow anticline, varying between 0.02 and 0.1 mm/yr since circa 200 kyr. Trishear forward deformation modeling of the fold indicates that the amplification of the observed fold could be caused by two shallow thrusts formed through a break-backward activation. This generated a decametric surface fold whose most recent growth was associated with bending-moment normal faulting in the crestal and forelimb region. Our observations demonstrate that near-surface compressive tectonics can be caused by blind thrusting, via a complex array of fault and folds: upward strain propagation and generation of shallow low-angle thrust and related folding seem to be mainly due to secondary fold-related faulting, according to an out-of-syncline thrusting mechanism.

International audiencehe Land Use and Cover Area frame Statistical survey (LUCAS) database on topsoil properties inEurope was used to map aeolian deposits. The points which satisfy the grain-size criteria of coversands, loess andtransitional facies were extracted from the rasters of predicted soil texture established by kriging of the LUCAS databy Ballabio et al. (2016). A comparison with already available maps, derived from a conventional ﬁeld approach,shows a good ﬁt in most of the tested areas. The new map, however, suggests a greater extension of loess, whichseems related to the inclusion of thin loess covers, usually omitted by conventional mapping, and the presence ofpreviously unmapped areas due to lack of survey or misinterpretation. The main source of aeolian particlescorresponds to glacio-ﬂuvial sediments at the margin of the Scandinavian and Alpine ice sheets. Coversands andloess form a broad band across northern Europe, and in the Rh^one, Rhine and Danube valleys. Large areas on theoutskirts of these deposits also received a signiﬁcant loess contribution, which has been reworked in slope deposits.Conversely, southern Europe is characterized by much less loess accumulation. The Atlantic coast has transgressivedune ﬁelds that penetrate inland to varying degre

“…The fresh aspect of these knapped stones indicates that no post-depositional movements took place, and the glossy surface of the fine-grained products can be ascribed to wind abrasion from quartz grains. Comparable alterations have been observed at the Ghiardo site and related to the loess depositional environment (Cremaschi et al, 2015(Cremaschi et al, , 2016. The Levallois technical system is present and well testified by at least 7 blanks ( Fig.…”

“…Key: 1 Pre-Quaternary rocks; 2 Late Pleistocene and Holocene alluvial plain; 3 present-day coast-line; 4 present-day 100m bathymetric line; 5 moraine systems; 6 loess deposits on fluvial and fluvioglacial deposits, moraine ridges and isolated hills; 7 loess on karst plateau; 8 direction of dominant winds during loess sedimentation. (Cremaschi et al, 2015), and for some sites near to the southern Alpine margin (Cremaschi et al, 1990). Therefore, the chrono-cultural context of open-air sites is, in most cases, partial and sketchy, often insufficient for the purpose of an inclusion in a global northern Italian perspective of the Late Middle Palaeolithic, known mostly on the basis of sheltered sites or caves in the Veneto and Friuli regions (Peresani, 2011(Peresani, , 2012Jéquier et al, 2015;Delpiano et al, 2018).…”

The final Middle Palaeolithic of northern Italy is almost exclusively known based on pluristratified sites in caves or rock shelter, which attest a certain technological variability within the Mousterian through the adoption of different knapping methods focused on the production of flakes or blades. The almost total lack of specialized and/or short-term open-air sites framed at this stage contributes to create a fragmentary and incomplete picture with regard to the last Neanderthal occupation of the area. For this reason, the Monte Netto site, an isolated hill at the northern margin of the Po Plain and at the foot of the Prealps, represents a key deposit to investigate this phase. Along the loess-palaeosoil sequence, investigated from a geochronological and pedological point of view, frequentations by Mousterian Neanderthal groups are attested at two different times, of which the most consistent is: associated to sediments dated to 44,400 ± 5.4 ky BP. The findings confirm the sporadic frequentation of marginal open areas during the cold, arid and highly fluctuating climate of the MIS 3, providing a more complete picture of the human occupation along the Po Plain Loess Basin (PPLB). An interregional comparison points out the clear intention, by the last Neanderthal groups of the Po Plain, of producing elongated supports by applying different methods, within a varied and organized system of resources exploitation evidenced by the selection of raw materials coming from more than 60 km.
