Geological Journal, EarlyView.In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Geological Journal, EarlyView.New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

A reevaluation of the late quaternary sedimentation in todos os Santos Bay (BA), Brazil
Anais da Academia Brasileira de Ciências, 2000 Todos os Santos Bay is a large ( 1000 km²), structurally controlled tidal bay in northeast Brazil. Three main drainage basins debouch into the bay, providing a mean freshwater discharge of 200 m³/s (prior to 1985), or less than 1% of the spring tidal ...

Ichnology of the Rhätsandstein in the Exter Formation (Triassic), Germany
Geological Journal, EarlyView.Trace fossils from the Rhätsandstein of southern Germany record repeated colonization of high‐energy shallow‐marine substrates before the Triassic–Jurassic transition. The assemblage reflects environmental and preservational controls on ichnodiversity.

Lithostratigraphy and depositional episodes of the Oligocene carbonate-rich Tikorangi Formation, Taranaki Basin, New Zealand [PDF]
, 2003 The subsurface Oligocene Tikorangi Formation is a unique and important oil producer in the onshore Waihapa-Ngaere Field, Taranaki Basin, being the only carbonate and fracture-producing reservoir within the basin. Core sample data from seven onshore wells

Journal of Quaternary Science, EarlyView.ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Modern carbonate sedimentary facies on the outer shelf and slope around New Caledonia [PDF]
, 2015 We investigated surface carbonate sediments at 33 sites on the outer shelf and slope around New Caledonia (163°-167°E, 20°-23°S), at water depths of 75-720m.
