The Skiddaw Group of Cumbria : early Ordovician Turbidite sedimentation and provenance on an evolving microcontinental margin. [PDF]
During the Early Palaeozoic, the southern British Isles were part of a microcontinent Eastern Avalonia. In the early Ordovician Eastern Avalonia was close to the continent of Gondwana. in high southern latitudes.

Bibliometric analysis of natural lakes and paleolakes origin of natural events [PDF]
This study explores studies on lakes and paleolakes originating from natural effects. The main objective is to perform a bibliometric analysis of research on naturally occurring lake environments worldwide, covering the period from 2014 to 2024.

A practical approach for discriminating tectonic settings of basaltic rocks using machine learning
Elucidating the tectonic setting of unknown rock samples has long attracted the interest of not only igneous petrologists but also a wide range of geoscientists.

Detrital zircon record and tectonic setting [PDF]
Funding: University of St AndrewsDetrital zircon spectra reflect the tectonic setting of the basin in which they are deposited. Convergent plate margins are characterized by a large proportion of zircon ages close to the depositional age of the sediment,

Temporal relations between mineral deposits and global tectonic cycles [PDF]
Natural Environment Research Council (grant NE/J021822/1) supported this research.Mineral deposits are heterogeneously distributed in both space and time, with variations reflecting tectonic setting, evolving environmental conditions, as in the ...

Tectonic discrimination diagrams revisited [PDF]
The decision boundaries of most tectonic discrimination diagrams are drawn by eye. Discriminant analysis is a statistically more rigorous way to determine the tectonic affinity of oceanic basalts based on their bulk-rock chemistry.

Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]
The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

Geochemical characterization of FE-1 well, Onshore Western Niger Delta Basin, Nigeria
Major oxides and trace elements analysis was carried out on ditch cutting samples of FE-1 well, Onshore, Niger Delta Basin, to define their oxygen condition, paleo-climatic conditions, provenance, tectonic setting, sandstone classification and maturity ...
