The top of the Querales Formation is well exposed at the Quebrada Corralito section, 17 m thick, in northern Venezuela. The section, dominated by siliciclastic accumulations of fine-grained sediments, preserves one cycle of transgressive-regressive phases of the deltaic environments facing the marine platform. An X-ray analysis revealed kaolinite as the main clay mineral. The age ranges from late Early Miocene to early Middle Miocenezones N8 to N9, Late Burdigalian to Langhian. The section shows low biodiversity, including eleven macroinvertebrate taxa and two ichnotaxa; at its base, it contains mostly plant debris and amber from the continent, thus revealing a continental source near the littoral zone. Its middle portion preserves macroinvertebrates from the littoral zone, but also including the cephalopod Aturia sp., transported by a hydraulic flow to an area of greater depth; these macroinvertebrates are absent from overlying sections, at a time in which the basin was flooded most. The X-ray diffraction on six rock samples revealed mainly the presence of quartz with calcite, subordinated plagioclase and traces of potassium feldspar. Other minerals that compose this stratigraphic section are pyrite, dolomite and siderite, but they are disseminated in a siltstone. The section is dominated by mudstone sediments. The succession is kaolinite in the most pure fraction, and in lesser proportion smectite and illite; the stratified illite-smectite, chlorite and chlorite-smectite are present in low quantity. The mineralogical components of a molluscan valve were also examined, showing abundant pyrite, and moderate amounts of siderite and dolomite. In a part of the section, we recorded a rich assemblage of calcareous microfossils with foraminifers, nannofossils and marine ostracods. In the
<p><strong>Abstract.</strong> The area of the “Foro Emiliano”, the current “Piazza del Municipio” in the coastal town of Terracina in southern Latium, consists of an articulated group of building belonging to different historical moments. On the roman pavement of the forensic square stand out: a Roman theatre, the urban cathedral, medieval houses, a roman temple and recent buildings dating from the first half of the 20th century. Thanks to recent funding the “Soprintendenza Archeologia, Belle Arti e Paesaggio per le province di Frosinone, Latina e Rieti” has undertaken the demolition of some modern houses insisting on the theatre’s porticus post scaenam and began an excavation of the entirely preserved cavea of the Roman theatre building. These interventions of urban archaeology were taken as an opportunity to plan an impressive 3D survey of the historic center, aiming: on one side at monitoring demolition and excavation work, offering a cartographic base for valorization projects, and on the other at the investigation of a vast monumental area. This paper analyses in detail the phases of integration, alignment, filtering and post processing of the acquired data, showing with evidence how the integration of active and passive sensors is the best approach in similar scenario.</p>
