Tuzla City (BiH): an example of geohazard induced by salt extraction
… 400-500 m. The mining operation changed the hydrogeological conditions enabling the downward flow of fresh water causing additional salt dissolution. This process induced severe ground subsidence during the last 60 years reaching up to 10 meters of sinking in the most affected area. Stress and …

Dinamica sedimentaria torbiditica in bacini confinati: margine orientale della Sardegna
… uno dei principali argomenti della ricerca sedimentologica sia in ambito puramente accademico che in ambito petrolifero-industriale. Gli studi recenti hanno enfatizzato l'influenza fondamentale della topografia preesistente del fondo marino sulla crescita e la morfologia sui fan di mare …

Mass-transport deposits on Mediterranean continental margins
… fill the basins with characteristic signatures. Geomorphological, seismo-stratigraphic, sedimentological and biostratigraphic data provide clues to: 1) define distinct failure mechanisms investigating on factors that determine dissimilar organization of coeval displaced masses, 2) reconstruct …

High-frequency Quaternary climate changes: a key to understanding present and future coastal scenarios
… low-lying coastal areas (e.g., Calvin et al., 2023). Placing current trends in the context of high-resolution past variability is therefore essential for informing effective adaptation strategies.

Stratigraphy and Palaeontology of the Late Cretaceous Wapiti Formation, west-central Alberta, Canada
… have been documented integrating several geological disciplines, including sequence stratigraphic methods, well-log signatures, facies analysis, and fossil associations. On the whole, particular attention has been given to 1) age and nature of both basal and upper contacts of the Wapiti …

NETWORK THEORY IN ICHNOLOGY: FROM BEHAVIOURAL TOPOLOGY TO THE DEPOSITIONAL ENVIRONMENT
This study aims to (1) develop quantitative approaches for the study of ichnological systems; (2) model, for the first time, ichnosites as networks; (3) analyze the response of ichnological systems to global dynamics, with particular regard to Late Paleozoic fluvial-influenced settings. In this …

FROM EAST TO NORTH-WEST AFRICA: MAGNETOCHRONOLOGY OF THE OLDEST AFRICAN ACHEULEAN SITES
… (Morocco), magnetostratigraphy coupled with geochemistry provided a chronostratigraphic framework extending from the Brunhes Chron (<0.773 Ma) to the Matuyama pre-Cobb Mountain (>1.210 Ma) subchron. Research conducted in the last decade revealed that the Acheulean emergence in East Africa …

I sedimenti superficiali della piattaforma interna del golfo di Cagliari. Relazioni tra moto ondoso, correnti indotte e processi di sedimentazione su sistemi di spiaggia campione
La presente tesi di dottorato ha come fine principale l’approfondimento delle conoscenze sedimentologiche sui fondali marini dell’area compresa tra Capo Spartivento e Capo Carbonara e dei meccanismi di apporto, ridistribuzione e sedimentazione attuale nella piattaforma interna. Particolare …

MISSISSIPPIAN MUD MOUNDS OF DERBYSHIRE (ENGLAND, UK): FACIES ARCHITECTURE AND BIOTIC EVOLUTION
Mud mounds are carbonate buildups, part of the reef spectrum, consisting dominantly of carbonate mud, with no or minor skeletal framework. The carbonate mud commonly shows texture (clotted peloidal, homogeneous with primary cavities), indicative of an origin through in-situ precipitation by …
