Lithostratigraphy of the Mesoproterozoic Vemork formation, central Telemark, Norway [PDF]

Bulletin of the Geological Society of Finland, 2007
The Vemork formation forms a c. 2 km thick volcanic-sedimentary unit above the 1510 – 1500 Ma old Tuddal felsic volcanite formation, the oldest unit of the Mesoproterozoic Telemark supracrustals in southern Norway.

Lodge moraines: a common yet underreported end‐moraine type—a review

Boreas, EarlyView.
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Review and Inventory of Pedological and Stratigraphical Knowledge for Investigating Shallow Landslides: A Case Study of the Cervinara Area (Central Campanian Apennines, Southern Italy)

Geosciences
Landslides are one of the most serious problems affecting large parts of the world. There are two approaches that are used to study the organization of these land cover features: firstly, an approach utilizing lithostratigraphic tools, where soils are ...

THE VALANGINIAN WEISSERT OCEANIC ANOXIC EVENT RECORDED IN CENTRAL-EASTERN SARDINIA (ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2018
Investigations on the S’Ozzastru section from the northern part of the Mt Albo area (central-eastern Sardinia, Italy) for integrated litho- bio- and chemostratigraphy allowed the identification of the Valanginian Weissert Oceanic Anoxic Event (OAE ...

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Ostracod assemblages indicating a low water level episode of Lake Peipsi at the beginning of the Holocene [PDF]

Estonian Journal of Earth Sciences, 2009
Three sediment cores from the northern part of Lake Peipsi in eastern Estonia were analysed for their ostracod content. The investigated sediments consist of late Weichselian glaciolacustrine varved and homogeneous clay, lake marl, and gyttja. Altogether

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Principal contradictions in the way of West Siberian berrias-aptian deposit’s regional stratigraphic schemes developing

Известия высших учебных заведений: Нефть и газ
The regional stratigraphic schemes of Jurassic and Cretaceous deposits in Western Siberia, approved over the last fifty years, reflect a conflict between the current clinoform concept and an outdated plane-parallel model.

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.
