Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Tourmalinites of the Brusque Group in the São João Batista-Tijucas area, State of Santa Catarina, Brazil [PDF]

open access: yesGeologia USP. Série Científica, 2013
The Dom Feliciano Belt, in the State of Santa Catarina, is represented by the Itaja and Brusque groups and the Florianpolis Batholith. The basal Rio do Oliveira Formation of the Brusque Group consists of metabasic/calc-silicate, metavolcanic-exhalative ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Emergence of Continents Stabilized the Bioavailability of Boron

open access: yesTerra Nova, Volume 38, Issue 4, Page 278-284, August 2026.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Polymer‐Based Passive Radiative Cooling A Structural Design Perspective

open access: yesEcoMat, Volume 8, Issue 7, July 2026.
This work categorizes structure‐oriented design strategies for polymer‐based passive radiative cooling into fibrous, porous, photonic/meta, and hybrid composite architectures. Each structural motif is shown to regulate solar scattering, infrared emissivity, and heat transport through distinct geometry‐driven mechanisms, offering a systematic pathway to

Effects of Dapagliflozin on Cardiovascular Outcomes in Patients With Type 2 Diabetes at Risk of Liver Fibrosis

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 7, Page 6142-6150, July 2026.
ABSTRACT Aims The fibrosis‐4 (FIB‐4) score is used to identify risk of advanced liver fibrosis. This post hoc analysis investigated its prognostic value for cardiovascular (CV) outcomes and its relevance to the effects of dapagliflozin. Materials and Methods DECLARE‐TIMI 58 was a randomised, placebo‐controlled phase 3 trial investigating dapagliflozin ...

P–T Modelling Constrains the Depth of Emplacement of the Porto Azzurro Pluton and Implies Minor Exhumation Caused by the Zuccale Fault (Island of Elba, Italy)

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 6, Page 440-469, July 2026.
ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

Tourmaline 40Ar/39Ar chronology of tourmaline-rich rocks from Central Iberia dates the main Variscan deformation phases

open access: yesGeologica Acta, 2009
During crustal thickening, metapelites taken to depth release boron-bearing hydrothermal fluids because of progressive heating and dehydration. These fluids swiftly percolate upwards, especially if the crust is being actively deformed, to form tourmaline

Petrography and Geochemistry of tourmaline nodules from Aderba leucogranite (northeast of Golpaygan) [PDF]

open access: yesپترولوژی, 2016
The Aderba leucogranite in the Golpayegan metamorphic core complex (GMC), a part of Sanandaj-Sirjan zone, host lentiform small (2*4 cm)(Type 1) and large (7*14 cm)(Type 2)tourmaline nodules. In terms of mineralogical features, the core of these two types
