Despite their markedly different structural setting, the northern and southern outer Albanides share a common tectonic evolution from detachment-dominated to ramp-dominated, basement-involved thrusting. The former process (mainly Oligocene Miocene) is essentially related with occurrence of thick décollement level represented by Triassic evaporites, while latter involves basement ramps splaying ...

We investigate the present-day orogenic architecture of Pyrenean-Cantabrian junction corresponding to a boundary between inverted rift segments using seismic interpretation, field data, and borehole information. This was formerly attributed major NNE-SSW striking Pamplona transfer fault segmenting Basque-Cantabrian Mauléon basins during both rifting convergence. Our study shows that results fro...

We explore theoretically the controls on dissolution of salt A, in an under-saturated brine of salts A and B. We show that, as the concentration of B increases, the dissolution rate of A decreases, for brine of given temperature. We also show that there is a sharper decrease in dissolution rate with increasing concentration, for concentrations of B above a critical value, where B limits the equ...

Palaeomagnetism of climatically sensitive sedimentary rock types, such as glacial deposits and evaporites, can test the uniformitarianism of ancient geomagnetic fields and palaeoclimate zones. Proterozoic glacial deposits laid down in near-equatorial palaeomagnetic latitudes can be explained by ‘snowball Earth’ episodes, high orbital obliquity or markedly non-uniformitarian geomagnetic fields. ...

The Archean-Proterozoic transition is characterized by the widespread deposition of organic-rich shale, sedimentary iron formation, glacial diamictite, and marine carbonates recording profound carbon isotope anomalies, but notably lacks bedded evaporites. All deposits refl ect environmental changes in oceanic and atmospheric redox states, in part associated with Earth’s earliest ice ages. Time-...

Abstract The present work is based mainly on core rock samples investigation of CSS-38 well, northwest Gulf Suez, Egypt. cores cover the whole South Gharib Formation (upper Miocene). stratigraphic succession Suez includes three mega units, recorded from old to young as pre-rift, syn-rift, and post-rift sediments. syn-rift sediments are Nukhul, Rudies, Kareem, Belayim Equivalent, Gharib, Zeit. r...
