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.

Characterising fractured basement using the Lewisian Gneiss Complex, NW Scotland: Implications for fracture systems in the Clair Field basement [PDF]

open access: yes, 2012
1-, 2- and 3-dimensional fracture network characteristics of the mainland Lewisian Gneiss Complex (LGC) have been used assess if the LGC is a suitable onshore analogue for the fracture networks within the offshore Clair basement.

Seismic analysis of the Niger Delta gravitational detachment system [PDF]

open access: yes, 2011
Ductile deformation of overpressured, fine-grained, argillaceous sediments (“mobile shale”) is commonly invoked to explain the deformation style at the base of thin-skinned, gravitational detachment systems.

Oligocene chronostratigraphy and planktonic foraminiferal biostratigraphy: Historical review and current state-of-the-art [PDF]

open access: yes, 2018
We review past and recent advances in Oligocene chronostratigraphy (and its internal subdivisions) and geochronology, the so-called “missing” Oligocene debate of the 1960s, and planktonic foraminiferal biostratigraphies of (sub)tropical and austral ...

Towards an improved Arctic Ocean chronostratigraphy

open access: yes, 2004
Concrete planning continues for launching the IODP Arctic Ocean expedition in summer 2004. The two major objectives are (1) to understand the long-term (50 Ma) and short-term (Neogene) paleoceanographic history and (2) the tectonic evolution of the ...

Planktonic foraminiferal biostratigraphy of the Miocene Arakawa Group in central Japan

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
We examined a planktonic foraminiferal biostratigraphy in the middle to upper Miocene Arakawa Group in central Japan. Chronostratigraphy has been already established for this sequence based on K-Ar ages of intercalated volcaniclastic layers. The studied
