Such endeavor requires well-preserved dynamic evidence of fossil human locomotion we are short of. Physical models of modern human locomotion predict individuals would perform voluntary step length adjustment as a function of slope gradient in order to minimize the energetic costof locomotion while maintaining balance and reasonably comfortable gait. The famous Roccamonfina volcano “Devil’s trails”, which are Middle Pleistocene Homo fossilized trackways, provide unique opportunity to validate such predictions for fossil human individuals. We studied the best-preserved Roccamonfina Devil’s trail to ascertain the dynamic behavior of the individual who left the trackway. We found Roccamonfina’s individual moved in a way which is dynamically equivalent to modern humans, adjusting gait as to minimize energy expenditure. We derived body mass and stature estimates for such individual, which fit perfectly with previously published figures for Middle Pleistocene hominins outside Africa.","PeriodicalId":49317,"journal":{"name":"Italian Journal of Geosciences","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3301/IJG.2019.03","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47645793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A precise lithological characterization was carried on at a macro- and micro-scale. Macrofauna includes, among others, abundant cephalopods and crinoids (loboliths). The biostratigraphic assignment to the uppermost Silurian-lowermost Devonian (Lochkovian) was possible basing on a moderately abundant conodont fauna, that provided thirty-two taxa belonging to thirteen genera, among which the new species Zieglerodina schoenlaubi.

The purpose of this comparison is to assess the homogeneity and provenance of detritus because quartz-rich sandstones of both formations are coeval having Burdigalian p.p. - Early Langhian age.The depositional domain of the Bifurto formation was located on the sinking Campania-Lucania carbonate platform whereas that of Numidian Flysch was within the Lagonegro-Molise Basin east of the Campania-Lucania Platform. The Bifurto sandstones have sub-arkose - quartzarenitic composition with high Fe2O3 contents (Fe2O3 in the range 2.85 wt% - 4.83 wt%), however, the whole composition varies in the same compositional range of the Numidian Flysch sandstones.The U-Pb detrital zircon ages in Bifurto sandstones range from 2551±40 Ma to 425±9 Ma and 93% of these age data is comprised in the same time lapse of detrital zircon ages of Numidian Flysch sandstones (3047±13 to 516±19 Ma). These ages suggest a provenance area consisting of ancient orogens in which Precambrian and Silurian rocks are present. The absence of Paleozoic - Mesozoic ages excludes provenance from Variscan or Alpine rocks. On this basis, the African Craton represents the exclusive source area of Bifurto sandstones as well as of Numidian Flysch sandstones outcropping in Southern Apennines. Similar deductions have been proposed for Numidian sandstones outcropping along the Betic and Maghrebian chains from Spain to Morocco, Algeria and Sicily.","PeriodicalId":49317,"journal":{"name":"Italian Journal of Geosciences","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3301/IJG.2019.02","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48594813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seismic processing and tomographic inversion of the first arrivals of multichannel seismic data were performed, allowing us to define geometries and velocities of the buried structures.Our data indicate the occurrence of a deformed Dinaric foredeep due to the Paleogene south-west migration of the External Dinaric chain and to the Neogene tectonic activity of the S-verging eastern South-Alpine chain. In addition, Plio-Quaternary transpressional fault systems produced structural highs such as the rocky outcrop of the Farra Hills rising from the plain.

The largerforaminiferal assemblage is dominated by Eulepidina, Heterostegina and Spiroclypeus. Nummulites, Operculina and Nephrolepidina make a subordinate but significant contribution. The concurrent range of the larger foraminiferal species present in the Porto Badisco Calcarenite, and in particular the presence of Spiroclypeus margaritatus and of Miogypsinoides complanatus-formosensis, indicates the late Oligocene Shallow Benthic Zone (SBZ) 23. The taxonomic composition of the larger foraminiferal assemblage of the Apulian Carbonate Platform is very similar to coeval assemblages of other localities of the western Tethyan realm (southern France, southern Spain, Malta, Greece), while some typical components of the SBZ 23 assemblages, like Heterostegina assilinoides and Eulepidina dilatata, are missing in more eastern areas (Turkey, India). Strontium isotope stratigraphy gives an age of 23.6 ± 0.5 Ma for the lower part of the Porto Badisco Calcarenite, constraining the chronostratigraphic calibration of the SBZ 23 within the latest Chattian. This calibration further supports the correlation between the SBZ 23 of the European Basins biozonal scheme with the Te 4 stage of the East Indian Letter Classification.","PeriodicalId":49317,"journal":{"name":"Italian Journal of Geosciences","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3301/IJG.2019.04","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49592071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sedimentary succession exposed at the study sites consists of red to grey clay with interbeddedbiodetrital limestone mainly composed by larger foraminiferal tests and resulting from turbidity or debris flows. Since planktonic foraminifers and nannofossils are absent or poorly preserved, the sedimentary successions have been referred to the late Eocene to the early Oligocene by the occurrence of displaced tests of largerforaminifers which are considered coeval to the foraminifers in the clay.Biostratigraphic correlations have been attempted by means of the first occurrence of lepidocyclinids and biometrical mean values of populations of Nephrolepidina praemarginata. Deep water agglutinated foraminifers (DWAF) assemblages in the background clay allowed the reconstruction of environmental variations marking a deepening tendency.Two breccia beds, one of which reaches 2.5 m in thickness, mainly composed of packstone-grainstone with Early and Late Cretaceous larger foraminifers and fragments of rudists, occur in the northern stratigraphic section as a result of the erosion of the paleoslope surface composed of the Upper Cretaceous rudist member of the Crisanti Formation. The lack of these deposits in the other twosections is due to bypassing. The assemblages and the stratigraphic settings are consistent with a deposition along a continental slope deepening northward, suggesting an ‘African’ provenance of the flows which contributed to displace and rework shallow-water material.","PeriodicalId":49317,"journal":{"name":"Italian Journal of Geosciences","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42270645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The landslide occurred along an unsurveyed, approximately 10-cm thick clayey intra-bed layer that mainly consists of smectite-group clayey minerals. Laboratory analyses indicate that it is very active and shows a high capacity to absorb water until reaching a swelling pressure of up to 1200 kPa. Mining activities reduced lithostatic load and facilitated rainwater infiltration down to this bentonitic layer, which led to fully softened conditions with a resulting severe reduction in the shear strength parameters. Under such conditions, the slope stability back-analysis was performed by the limit equilibrium method, considering a planar rock slope failure with tension cracks and with different water level heights. The results show that a small increase of water pressure was sufficient to exceed the factor of safety. Stratigraphically, this layer can be correlated with the Lower Campanian Bentonitic Layer already reported in other sites of Central Italy. Therefore, the potentially great spatial extent of this layer and the possibility that the reported conditions may occur in other similar settings, make it important to identify its presence in order to prevent analogous situations.","PeriodicalId":49317,"journal":{"name":"Italian Journal of Geosciences","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49533379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study supports the existence of a thickMesozoic succession, onlapping the Hercynian basement, preservedbelow the Cenozoic succession in the Asinara Gulf, suggesting that theNurra succession continues northward below the sea. The Mesozoic succession is bordered by a major, east-dipping normal fault, east the Asinara Island ridge. The faults recognized in the seismic profile indicate a prevailing strike slip/transtensional tectonics, questioning the role of compressional tectonics suggested in a previousinterpretation. The obtained results also indicate the potential of reprocessing of existing seismic profiles, whose interpretation can be significantly updated thanks to the development of new processing procedures and to the continuous upgrade of the regional geological knowledge.","PeriodicalId":49317,"journal":{"name":"Italian Journal of Geosciences","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41825931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
