Abstract: Abstract The 87Sr/86Sr, REE and Mo U systematics were investigated in Miocene seep carbonates formed on accretionary ridges at the front of the northern Apennine wedge. Here we evaluate fluid sources, seepage intensity and redox… read more here.

DOI: 10.1016/j.chemgeo.2020.119857
Abstract: Abstract Rare earth element and yttrium (REY) systematics of authigenic seep carbonates can provide insights into the physico-chemical characteristics of seep systems and allow discrimination of carbonate precipitation under seawater- or porewater-dominated fluid regimes. However,… read more here.

DOI: 10.1016/j.chemgeo.2021.120101
Abstract: Abstract The magnesium (Mg) isotopic composition of marine carbonate has been used as a proxy to constrain the geochemical composition of seawater and to trace the global Mg cycle. Sulfate-driven anaerobic oxidation of methane (SD-AOM)… read more here.

DOI: 10.1016/j.jseaes.2018.04.037
Abstract: Abstract Authigenic carbonates and pyrite associated with sulfate-driven anaerobic oxidation of methane (AOM) at methane seeps provide archives to explore the biogeochemical processes involved and seepage dynamics over time. The wide range and extremely high… read more here.

DOI: 10.1306/06192019025
Abstract: Despite the obvious link between hydrocarbon seepage at the surface and the activity of petroleum systems at depth, the majority of studies on seep carbonates concentrate on shallow aspects, whereas they are rarely oriented toward… read more here.
