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

open access: yesSedimentology, 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 ...

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

open access: yesSedimentology, 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

To the question of the intensification of the processes of uranium extraction from refractory raw materials

open access: yesMetalurgija, 2019
Recently, one of the main directions for increasing the extraction of uranium from difficult-to-hide ores is the use of intensifiers, which allow the most complete transfer of uranium from one valence state to another. In the article, the catalyst “M-1”,

Solvent Extraction of Uranium Using Alkylamines

open access: yesJournal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1963
The new conversion refining process using high molecular weight alkylamines was developed in order to obtain directly highly purified UF4 or UO3 from ore leaching solution without the precipitation process of yellow cake. Suitable conditions for each of the extraction, conversion and stripping process were described, and also the flow diagram of this ...
