Late Miocene – Early Pleistocene paleogeography of the onshore central Hawke’s Bay sector of the forearc basin, eastern North Island, New Zealand, and some implications for hydrocarbon prospectivity [PDF]

, 2008
The timing of trap formation in relation to the timing of source rock burial and maturation are important considerations in evaluating the hydrocarbon prospectivity of onshore parts of the forearc basin in central Hawke’s Bay.

Detrital heavy minerals constraints on the Triassic tectonic evolution of the West Qinling terrane, NW China: implications for understanding subduction of the Paleotethyan Ocean [PDF]

, 2014
We have examined the Triassic sediments in the west Qinling terrane, northeastern Tibet. These sediments consist mainly of flysch and shallow-sea and fluvial deposits with abundant lithic and heavy mineral detritus, sandwiched between and overlying Late ...

Crustal Architecture and Low‐Temperature Geochronology of an Apparent Cycladic Tectonic Window (NE Attica, Greece): Insights Into Imbrication in Subduction Settings

Tectonics, Volume 44, Issue 11, November 2025.
Abstract Understanding the timing and configuration of tectonic nappes in collapsed orogens is integral to reconstructing its geodynamic evolution. Northeastern Attica lies between bivergent Miocene detachment systems and has historically been interpreted as a tectonic window exposing the lowest nappe of the Hellenides, the Basal Unit.

Alternative interpretation of the Bystrica Unit in Klanečnica KLK-1 borehole (Magura Nappe)

Mineralia Slovaca
In 1986, the KLK-1 (Klanečnica) borehole was drilled northwest of Moravské Lieskové as part of a regional oil and gas exploration programme. The well reached a total depth of 662 m and was intended to verify the occurrence and potential accumulation of ...

Precambrian Greenstone Belts of North Baffin Island, Canadian Arctic: Geochronological Constraints on Magmatism and Stratigraphy in the Rae Craton

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Supracrustal greenstone belts of the Rae craton of north Baffin Island have been historically attributed to the Mary River Group (MRG), a key tectonostratigraphic unit of economic significance. Best‐preserved exposures of supracrustal rocks occur within the Eqe Bay Greenstone Belt.

The Middle Jurassic succession in the central sector of the Pieniny Klippen Belt (Sprzycne Creek): implications for the timing of the Czorsztyn Ridge development

Geologica Carpathica, 2015
In this study, we revisit the stratigraphic age and discuss sedimentary characteristics of the lower Middle Jurassic turbidite deposits (“black flysch”) of the Szlachtowa Formation, as well as the under- and overlying members of the Sprzycne Creek ...

Implications of Hydrocarbon and Helium Gas Analyses of Springs from the Ouachita Mountains, Arkansas [PDF]

, 1984
One hundred and three ground water samples (predominantly springs) were analyzed for headspace light hydrocarbon gases and helium. Four of the formations (Arkansas Novaculite, Bigfork Chert, Stanley Shale, and Womble) having the highest mean methane ...

Reconstructing Early Cenozoic Paleodrainage and Tectonic Evolution in the Southeastern Tibetan Plateau: Evidence From Detrital Zircon and Tourmaline Provenance

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Paleogene sedimentary basins of southeastern Tibet record sediment dispersal patterns associated with crustal deformation during the early stages of the India–Asia collision. We present detrital zircon U–Pb geochronology, tourmaline geochemistry, and petrographic data from the Gonjo and Mangkang basins that suggest a reginal interconnected

Fate of the Late Triassic Songpan-Ganzi Basin in the eastern Paleo-Tethys Ocean: Geochemical and geochronological constraints in the NE Tibetan Plateau

Journal of Asian Earth Sciences: X
The Songpan-Ganzi Basin in the northeastern Tibetan Plateau preserves well-developed Late Triassic flysch sequences, making it an ideal region for investigating the provenance and tectonic evolution of the basin.

Praesphaerammina, a new genus of Cenozoic deep-water agglutinated foraminifera from the Carpathian flysch deposits [PDF]

, 2000
The genus Praesphaerammina Kaminski and Filipcscu is newly described based on a revision of the type species Cystammina subgaleata Vasicek 1947. The genus differs from the Holocene genus Sphaerammina Cushman 1910 emend.
