Integrated analyses of Calcareous Nannofossils and Radiolarians were carried out in the Monte Kumeta (Sicily) to better define the age of the siliceous sediments (Membro Radiolaritico Intermedio = MRI), which results to be early-middle Bathonian to early

Electrical (ER) corrosion sensors made of AISI 1010 carbon steel are tested under gamma irradiation (0.25–1.00 MGy) for deep geological radioactive waste disposal applications. Despite the high dose rates of this study, ER sensors remain reliable, showing no significant loss in measurement performances.

On the peritidal cycles and their diagenetic evolution in the Lower Jurassic carbonates of the Calcare Massiccio Formation (Central Apennines) [PDF]
This paper shows the environmental changes and high-frequency cyclicity recorded by Lower Jurassic shallow- water carbonates known as the Calcare Massiccio Formation which crop out in the central Apennines of Italy.

Abstract We describe the Hettangian Caenogastropoda and Heterobranchia of the Luxembourg Sandstone Formation, a wedge of clastic sediments deposited along the eastern margin of Paris Basin during the Early Jurassic. Five new genera and 11 new species are erected: Bourguetia bipartita sp. nov., Globularia delsatei sp. nov., Oonia feidtorum sp.

Jurassic tracks and HS2: a twenty‐first century journey
The biggest UK railway construction site since the nineteenth century has exposed a near‐complete time slice through the entire Jurassic succession of central England. This is yielding a wealth of stratigraphical, palaeobiological and palaeoenvironmental data that is otherwise generally poorly exposed at the present day.

Time-dependent behaviour of the Callovo-Oxfordian claystone-concrete interface
In the context of the Cigéo project, the French National Radioactive Waste Management Agency (Andra) is studying the behaviour of a deep geological facility for radioactive waste deposit in the Callovo-Oxfordian (COx) claystone.

Investigating the swelling pressure of compacted crushed-Callovo-Oxfordian claystone [PDF]
Abstract This paper presents an experimental study on the swelling pressure of heavily compacted crushed Callovo-Oxfordian (COx) claystone at a dry unit mass ρd = 2.0 Mg/m3 using four different methods: constant-volume, swell-reload, zero-swell and adjusted constant-volume method. Results show that the swelling pressure varies in the range of 1–5 MPa

Oxford: W.J. Arkell’s coral city
The city of Oxford, in south‐central England, is partly surrounded by hills on which coral‐rich limestones crop out. The coral developments constitute small reefs and formed during a widely documented Late Jurassic (mid‐Oxfordian) warming episode, near the northern limit of reef growth at that time.

Coupled THM analysis of long-term anisotropic convergence in the full-scale micro tunnel excavated in the Callovo-Oxfordian argillite [PDF]
The main purpose of this paper is to analyse the convergence measurements of the ALC1604 in situ heating test carried out in the Callovo-Oxfordian claystone formation (COx) in the Meuse/Haute-Marne underground research laboratory (MHM URL).
