Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Magnetic‐lens‐generated polarized neutron beam with enhanced intensity and Q resolution for small‐angle neutron scattering

Journal of Applied Crystallography, Volume 59, Issue 1, Page 69-79, February 2026.
While maintaining or even improving Q resolution, a long array of short‐focal‐length magnetic lenses, with zero transmission loss and no diffuse scattering, successfully polarized and enhanced the intensity of neutron beams for small‐angle neutron scattering at momentum transfer Q > 0.1 nm−1.We installed a 30 mm‐bore 3.2 m‐long magnetic lens in the ...

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

GATHERING THE HARVEST: THE COLLECTION AND TRANSPORTATION OF AGRICULTURAL PRODUCE IN ROMAN CAMBRIDGESHIRE AND PETERBOROUGH

Oxford Journal of Archaeology, Volume 45, Issue 1, Page 68-92, February 2026.
Summary When Rome colonized Britain, it created a transport network spanning the province. This transformed the Iron Age economy, creating large new markets which in turn supported specialized manufacturing. This article explores the impact of transportation on Roman agriculture – the core of the Romano‐British economy.
