Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract Understanding dissolved organic carbon (DOC) fluxes in boreal freshwater systems is critical for constraining high‐latitude carbon budgets and anticipating climate‐driven changes. Here, we present a retrospective assessment (2000–2024) of DOC fluxes in the Upper Mackenzie River watershed, focusing on Great Slave Lake (GSL), a key hydrological ...

Facies and sequence stratigraphic implications of the Statfjord formation (upper triassic-lower Jurassic), northern north sea, UK [PDF]
, 1996 Detailed sedimentological logging of core, and interpretation of wireline logs from the Brent Oil Field, northern North Sea, have allowed for the identification of sedimentary facies and environments of the Upper Triassic-Lower Jurassic Statfjord ...

Lower Devonian Tortilicaulis is an early tracheophyte and not a bryophyte
Fossil ImprintTortilicaulis D.Edwards is a genus of long-standing unknown affinity in which there are two species: the holotype T. transwalliensis D.Edwards, known only from coalified compressions and T. offaeus D.Edwards, Fanning et J.B.Richardson, known from an assemblage of minute, exceptionally well preserved charcoalified fossils from a Lochkovian deposit in ...

Tectonics, Volume 45, Issue 6, June 2026.Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

Tectonics, Volume 45, Issue 6, June 2026.Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...
