Taxonomy and dated molecular phylogeny of Allium oreophilum sensu lato (A. subg. Porphyroprason) uncover a surprising number of cryptic taxa

open access: yesTAXON, EarlyView.
Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.

Geochemical studies, magmatic evolution, microstructures and replacement mechanisms in Jebale-Barez granitoid Complex (East and Southeast Jiroft)

open access: yesJournal of Economic Geology, 2017
Introduction The Jebale-Barez Plutonic Complex (JBPC) is composed of many intrusive bodies and is located in the southeastern province of Kerman on the longitude of the 57◦ 45 ' east to 58◦ 00' and Northern latitudes 28◦ 30' to 29◦ 00'.

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

open access: yesBoreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

open access: yesBoreas, EarlyView.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

Thick-Skinned and Thin-Skinned Tectonics: A Global Perspective

open access: yesGeosciences, 2017
This paper gives an overview of the large-scale tectonic styles encountered in orogens worldwide. Thin-skinned and thick-skinned tectonics represent two end member styles recognized in mountain ranges.

Historical Biogeography of Spiny Lobsters in the Genus Panulirus (Achelata: Palinuridae)

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Panulirus is the spiny lobster genus with the most living species, containing 22 recognised species split into two lineages distinguished by habitat preference. Diversification has been proposed to occur due to geographic events affecting the distribution of adults and the dispersal potential of long‐lived larvae by oceanic currents ...

Onset of double subduction controls plate motion reorganisation

open access: yesNature Communications
Face-to-face double subduction systems, in which two oceanic plates subduct toward each other, are essential elements of plate tectonics. Two subduction zones in such systems are typically uneven in age and their spatially and temporally variable ...

Petrochemical characteristics of late Paleozoic magmatic rocks of the Mandakh area, southeast Mongolia

open access: yesMongolian Geoscientist, 2018
The late Paleozoic magmatic rocks are widely distributed in the Mandakh area which is located in the Gurvansaikhan and Manlai terrains, where porphyry Cu deposits occur.

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

Ophiolites in the Central Asian Orogenic Belt record Cambrian subduction initiation processes

open access: yesCommunications Earth & Environment
Subduction initiation remains elusive because no present example exists. Ophiolites formed over nascent subduction zones in the past provide the key to constraining the processes of subduction initiation.
