Developing Habitat Descriptors for a Threatened Cryptic Worm‐Lizard to Determine Potential Habitat Under the NSW Biodiversity Offset Scheme in Australia

Ecological Management &Restoration, Volume 27, Issue 3, September 2026.
ABSTRACT Understanding the habitat requirements and potential distribution of threatened species is fundamental to mitigating threats and protecting significant populations. In Australia, a range of studies have been undertaken into the ecology and habitat requirements for the nationally threatened pink‐tailed worm‐lizard (Aprasia parapulchella) in the

Multi-analytical characterization and radiation shielding assessment of natural ophiolitic rocks: a combined experimental, mineralogical, and simulation analysis

Scientific Reports
Ophiolitic suites derived from oceanic crust are rich in ferromagnesian and mafic minerals and exhibit relatively high densities, making them promising and economical materials for radiation shielding.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 625-647, September 2026.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Metamorphic Reactivity Influences Amphibole Creep Behaviour

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 611-632, September 2026.
ABSTRACT The rheological behaviour of solid‐solution minerals may play an important role in determining how metamorphic crust accommodates deformation. Whether or not a mineral's deformation is diffusion or dislocation‐mediated depends on a range of extrinsic variables such as stress, strain rate and temperature, as well as intrinsic variables such as ...

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

~990 Ma peak granulitic metamorphism and amalgamation of Oaxaquia, Mexico: U–Pb zircon geochronological and common Pb isotopic data

Revista Mexicana de Ciencias Geológicas, 2018
The ~1 Ga Oaxacan Complex is the largest exposure of the Oaxaquia terrane of Mexico. Microprobe analysis of co-existing ortho- and clino-pyroxene, garnet, ilmenite and plagioclase indicate metamorphic conditions of 735 ± 5° C and 7.7 ± 0.1 kbar in the ...

Architecture of the Patrimonio Fault System and the Miocene Post‐Orogenic Extension in Alpine Corsica (France)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The exhumation of Alpine Corsica is the result of Oligocene‐Miocene lithospheric back‐arc extension in the wake of the eastward migration of Apenninic subduction. Although the geometry, kinematics and timing of ductile detachments are well constrained, the brittle extension leading to final exhumation of Alpine Corsica is less documented.

Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

Evolution in Fluid Composition During Subduction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Fluid‐rock reactions play important roles in seismicity, arc‐magma chemistries, and volatile cycling at convergent plate boundaries. In subduction environments, metamorphic reactions involving hydrous fluids facilitate metasomatic alteration and mass transport.
