The role of ocean anoxia as a cause the end-Triassic marine mass extinction is widely debated. Here, we present carbonate-associated sulfate δ
Pressure solution processes taking place during diagenesis deeply modify the hydraulic properties of carbonates, affecting their mechanical layering and hence dimension, distribution, connectivity high-angle fractures. The formation stylolites is controlled by texture host rock therefore depositional environment diagenetic that involve it. This study reports results a multidisciplinary carried out on Jurassic–Cretaceous carbonate platform in southern Italy. goal to unravel control exerted...
The end-Triassic mass extinction (ETME) was associated with intensified deep-water anoxia in epicontinental seas and mid-depth waters, yet the absolute oxygenation state shallow ocean is uncharacterized. Here we report carbonate-associated iodine data from peritidal Mount Sparagio section (Southern Italy) that documents ETME (~ 200 Ma) western Tethys. We find a sharp drop carbonate I/(Ca + Mg) ratios across horizon persisting into Early Jurassic. This records local dissolved oxygen iodate...
The results of an integrated stratigraphic, structural, geophysical, and geochemical study reveal the presence a crustal discontinuity in western Sicily that, at present, runs roughly N-S along band from San Vito Lo Capo to Sciacca. boundary between two zones this is nearly orthogonal main thrust propagation Sicilian thrust-and-fold belt. different Permian Tertiary sedimentary evolution recorded by appears related discontinuity, with thick carbonate platforms sector facing deepwater...
Changes in firing practice have been suggested as representing a revolution ceramic technology at the beginning of Bronze Age Crete. The introduction kiln structures has held responsible for such change, perhaps by newcomers to island, along with other innovative technologies. However, these hypotheses were often based on limited analytical data and mostly macroscopic examination. This paper re-examines suggestion transformation presenting analyses rich assemblage from site Phaistos...
Abstract. Because of its high seismic hazard the urban area Oliveri has been subject first level microzonation. The town develops on a large coastal plain made mixed fluvial/marine sediments, overlapping complexly deformed substrate. In order to identify points probably suffering relevant site effects and define preliminary Vs subsurface model for microzonation, we performed 23 HVSR measurements. A clustering technique continuous signals used optimize calculation curves. 42 reliable peaks...
Estimating the accurate position of shoreline over time can be challenging. We propose a new approach to delimit from remotely sensed images simply and accurately. This treats pixels as simultaneous radiometric measurements and, by examining distance between iso-radiometry lines, assumes in where behavior changes more suddenly. The analyses conducted applying this coastline extraction underscore its significant flexibility. Specifically, yields promising outcomes even if applied variety...
Abstract Tectonic processes are widely considered as a mechanism causing carbonate platform margin instabilities leading to the emplacement of mass transport deposits and calciturbidites. However, only few examples establishing clear link between tectonics re‐sedimentation known from literature. The two‐dimensional three‐dimensional wire‐cut walls hundreds quarries extracting ornamental limestones (for example, Perlato di Sicilia ) Western Sicily Cretaceous Escarpment in Italy expose series...
Abstract The Viggiano Mt. platform carbonates form a layered succession cross-cut by dense array of pressure solution seams, and five sets fractures veins, which together sub-seismic structural network associated with polyphasic tectonic evolution. To assess the influence exerted depositional diagenetic heterogeneities on fracture geometry, distribution multiscale properties, we present results stratigraphic, petrographic, mineralogical mesoscale analyses conducted at Mountain, southern...
Xyloglucan is a natural polysaccharide having cellulose-like backbone and hydroxyl groups-rich side-chains. In its native form the polymer water-soluble forms gel only in presence of selected co-solutes. When given fraction galactosyl residues are removed by enzymatic reaction, acquires ability to aqueous solution at physiological temperatures, property great interest for biomedical/pharmaceutical applications. This work presents data on effect temperature increase degalactosylated...
