The Imperial Fora are a monumental area that shows all the complexity of the historical stratifications and, at the same time, the damages brought to an archaeological and urban ensemble of great value, because of many operations managed in unembarrassed way, without precise programs nor adequate projects. The campaign of excavations made in 1998-2000, even if was finalized to the certain identification of the imperial structure there buried, has brought again the attention to that building tissue of very high historical interest that during the centuries overlapped to them.

The aim of this work is to reproduce a metre-scale facies heterogeneity 3D model of the Chattian Porto Badisco Calcarenite carbonate ramp outcropping in the Salento Peninsula (southern Italy). However, in shallow-water carbonate systems, capturing metre-scale facies heterogeneity in three-dimensional models remains controversial due to the possibility of facies coexistence and because their association can change through time and space.

The Eocene-Oligocene Transition is a key interval in the evolution of the modern climate, representing the last greenhouse-icehouse transition faced by the Earth. Shallow-water carbonate systems hold essential information of the global changes related to the E-O Transition. In this work, we focus on the Majella Mountain carbonate ramp to identify the shallow-water sedimentary expression of the oceanographic and sea-level changes related to the E-O Transition, and to compare it with the deep-marine records and the coeval shallow-water successions.

Temperature-dependent clay minerals and vitrinite reflectance data, surface and subsurface geological constraints were used to unravel the burial evolution of the Ordovician-Quaternary sedimentary successions from the inner to the outer zones of the Zagros fold-and-thrust belt in the Fars province (Iran). These sedimentary successions were buried to their thermal maxima during early to late diagenesis, achieving temperatures corresponding to the immature to early mature stages of hydrocarbon generation.

Climate evolution of the Mediterranean region during the Holocene exhibits strong spatial and temporal variability, which is notoriously difficult for models to reproduce. We propose here a new proxy-based climate synthesis synthesis and its comparison – at a regional ( ? 100 km) level – with a regional climate model to examine (i) opposing northern and southern precipitation regimes and (ii) an

Central Mediterranean shelves show a large variability in morphology (width, slope, unevenness), stratigraphy (different thickness of depositional bodies resulting from the last climatic/eustatic cycle) and sedimentology (shelf-mud offshore of the main river mouths, bioclastic sediment in under-supplied areas) because of their geologically young age and complex geological setting. To better understand relative sea-level changes during the Holocene, people have to consider that its variations are the sum of eustatic, glacio-hydro-isostatic and tectonic factors.

The Early Bronze IVB (EB IVB, c. 2300-2000 BC) pottery horizon of Western Inland Syria has been object of intense study for decades, and it is well known, being attested at a large number of sites spanning east-west from the Orontes Valley to the Jabbul. However, until less than a decade ago, internal periodization of this period was possible only by referring to Hama, the only site that had provided a long EB IVB stratigraphic and ceramic sequences excavated in the 1930s.

Our study aims to reconstruct climate changes that occurred at Lake Ohrid (south-western Balkan Peninsula), the oldest extant lake in Europe, between 160 and 70?ka (covering part of marine isotope stage 6, MIS 6; all of MIS 5; and the beginning of MIS 4). A multi-method approach, including the "Modern Analog Technique" and the "Weighted Averaging Partial Least-Squares Regression", is applied to the high-resolution pollen sequence of the DEEP site, collected from the central part of Lake Ohrid, to provide quantitative estimates of climate and bioclimate parameters.
