Trace element and Sr-Nd-Pb isotope geochemistry of Rungwe Volcanic Province, Tanzania: Implications for a superplume source for East Africa Rift magmatism

Frontiers in Earth Science, 2014
The recently discovered high, plume-like 3He/4He ratios at Rungwe Volcanic Province (RVP) in southern Tanzania, similar to those at the Main Ethiopian Rift in Ethiopia, strongly suggest that magmatism associated with continental rifting along the entire ...

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Sequence stratigraphy in Proterozoic successions

Geology, 1988
Sedimentological logging and facies mapping have been used to identify depositional sequences bounded by subtle but regionally persistent unconformities in rocks of Proterozoic age in the western United States, South Australia, and northwestern Canada. We conclude from these studies that the sequence stratigraphic approach is of considerable importance

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2855-2879, September 2026.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.
