Mediterranean-type bauxite deposits in Sardinia formed during the Upper Cretaceous (Cenomanian–Turonian) due to emergence of south European margin Alpine Tethys an area affected by monsoonal climate. The were controlled structural frame a transpressive tectonic regime and unconformably overlie carbonate rocks different age composition, which led formation types. In general, Sardinian deposits, boehmite is main Al-phase, kaolinite Si-rich mineral, hematite as well goethite are Fe-rich phases....
Around 30 million tonnes of bauxite residues (red muds), resulting from aluminium extraction via Bayer process, are stored at the Porto Vesme disposal site in southern Sardinia, Italy. The primary crystalline components these include iron oxides, hydroxides, titanium silicates, carbonates, and halides, along with several minor phases. Lanthanide-rich phosphate minerals occasionally detected. Na-aluminosilicates results desilication, while hydroxides oxyhydroxides residual alumina minerals,...
Summary: The potential for cardiac arrhythmia was studied in an experimental focal epilepsy induced hemispherectomized rats by topical application of buffered penicillin G onto the thalamus. epileptic burst triggered and hemodynamic responses, as simultaneously monitored arterial pressure, hypothalamic heart activity. During interictal activity, single a short‐latency arrhythmia, characterized sinus bradyarrhythmia junctional rhythm, lengthening intervals between sphygmic waves with...
Bauxite deposits in Italy mainly distribute Sardinia and Adria regions within Cretaceous carbonate sequences. Parental affinity of Italian bauxite has long been a controversial problem. At least four potential sources have proposed: (1) debris autochthonous marlstones; (2) alluvial sheets from the weathered Variscan basement; (3) weathering materials North Africa (4) bimodal volcanism Dinaric Carpatho-Balkan orogenic belts. In this study, total 374 detrital zircon U-Pb ages 86 Hf isotope...

This study compares, for the first time, mineralogy and geochemistry of two residual-clay deposits in NW Sardinia (Nurra district) that formed at different times tropical sub-tropical climates. Both represent palaeosols with deep-weathered residual profiles overlie Mesozoic carbonate rocks were deposited on south European palaeomargin. The older alterite is Cenomanian–Turonian age grades upward into a horizon karstic bauxite, whereas younger unit occurs within alluvial Late Neogene age....
At S anta F ilitica, a R oman settlement in north‐western ardinia occupied until the ninth century ad , archaeological excavations have found remnants of furnace consisting semi‐circular base made stony slabs and tiles bound with clay. The is attached to wall age. Layers sixth bearing several variously oxidized slags, were close furnace. These findings first testify an ironworks ardinia, within well‐defined context. XRPD SEM – EDS mineralogical textural analyses suggest that slags derive...
Abstract Electrical resistivity tomography (ERT) and ground penetrating radar (GPR) surveys were conducted in the Anghelu Ruju hypogeic necropolis northern Sardinia (Italy). The main purpose was to calibrate both techniques on a known already dug tomb. After calibration survey extended neighbouring unexplored area with aim demonstrate new structures. A comparison of high‐resolution GPR ERT models made, their results are discussed terms providing more complete picture that would not be...
