Chronostratigraphy and tectono‐sedimentary history of the Eastern South Pyrenean foreland basin (Ripoll Syncline, North‐East Spain)

open access: yesThe Depositional Record
This paper contributes to an understanding of the tectono‐sedimentary evolution of the South Pyrenean foreland system by reviewing the chronostratigraphic framework of the basin infill in its eastern sector. Six sections are analysed and cross‐correlated

Plio-Pleistocene changes in water mass exchange and erosional inputs in the Fram Strait [PDF]

open access: yes, 2011
We determined the isotopic composition of neodymium (Nd) and lead (Pb) of past seawater to reconstruct water mass exchange and erosional input between the Arctic Ocean and the Norwegian-Greenland Seas over the past 5 Ma.

Late Holocene Abrupt Changes in the Fluvial Dynamics of the Tiber Valley Catchment (Rome, Italy): An Impact of the 4.2 Event?

open access: yesQuaternary
In the present work, we investigate the post-glacial aggradation of three tributary valleys draining the left hydrographic basin of the Tiber River in central Rome: the Murcia, Caffarella, and Grottaperfetta valleys.

Integrated chronostratigraphy of Proterozoic-Cambrian boundary beds in the western Anabar region, northern Siberia [PDF]

open access: yes, 1996
Carbonate-rich sedimentary rocks of the western Anabar region, northern Siberia, preserve an exceptional record of evolutionary and biogeochemical events near the Proterozoic/Cambrian boundary. Sedimentologically, the boundary succession can be divided
