A spectacular field of columnar carbonates has been discovered on the Montenegrin margin
in the southern Adriatic Sea at a depth of about 450 m. The site exposes many columnar …

Abstract The Stirone River section in the Italian Northern Apennines hosts a rare example of
Pliocene age hydrocarbon-imprinted carbonates in the Mediterranean Basin associated with …

Paola Ridge, along the NW Calabrian margin (southern Tyrrhenian Sea), is one of the few
reported deep sea sites of precipitation of authigenic carbonates in the Tyrrhenian Sea …

Cold seep carbonates are remarkable fossil records of hydrocarbon seepage and related
conduits. In the present research, we analysed the carbon and oxygen isotopes, rare earth …

Abstract Methane Derived Authigenic Carbonate (MDAC) concretions have been recently
exposed in the Pleistocene Argille Azzurre Fm. outcrop** along the Enza riverbanks …

At a Pliocene methane seep site in Taiwan characterized by numerous tubular carbonate
bodies and bivalves, a half meter-long dolomitic concretion containing a lucinid bivalve …

Carbonates are widespread at methane and petroleum seeps and are often precipitated as
consequence of an alkalinity increase due to the anaerobic oxidation of methane (AOM) or …

Authigenic carbonates are frequently associated with methane cold-seep systems, which
extensively occur in various geologic settings worldwide. Of interest is the relation between …

Peculiar carbonate bodies occur in distinct marl layers of the Marnes Bleues Formation
(Aptian–Albian, Vocontian Basin, Southern France). The carbonate conduits exhibit pipe-or …

The gas-productive Bonaccia area located at ca. 80–90 m below sea level offshore Ancona
(Central Adriatic Sea) is site of hydrocarbon-derived carbonate production. The carbonates …
