Geological Journal, EarlyView.The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...

Geology and petrology of the margin of the Rhum ultrabasic intrusion, Inner Hebrides, Scotland
, 2015 Country rocks surrounding the Rhum Tertiary ultrabasic complex have experienced severe thermal metamorphism, partial melting and mobilization resulting in the formation of extensive areas of intrusion breccia.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Late Cretaceous lithospheric extension in SE China: Constraints from volcanic rocks in Hainan Island
, 2015 Petrological, geochemical and in-situ zircon U-Pb dating and Hf-isotope analyses have been carried out on a suite of basalt-andesite-rhyolite volcanic rocks exposed in the Liuluocun area, Hainan Island, SE China.

Journal of Quaternary Science, EarlyView.ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

, 2023 The mercury (Hg) budget outgassed in the atmosphere from active volcanoes is genetically related to the underlying magmatic plumbing system. However, the source, distribution, and transport of Hg in magmas remain uncertain. Differentiation and/or crustal

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone
Journal of Quaternary Science, EarlyView.ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Journal of Quaternary Science, EarlyView.ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and
