Production rate calibration for cosmogenic 10Be in pyroxene by applying a rapid fusion method to 10Be-saturated samples from the Transantarctic Mountains, Antarctica [PDF]
GeochronologyMeasurements of multiple cosmogenic nuclides in a single sample are valuable for various applications of cosmogenic nuclide exposure dating and allow for correcting exposure ages for surface weathering and erosion and establishing exposure–burial history.

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?
Geological Journal, Volume 61, Issue 4, Page 1029-1040, April 2026.The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

Optimization of performance and composition for glass ceramics prepared from mixing molten slags
工程科学学报, 2019 The direct preparation of materials from high-temperature slag is an effective way for the integrated utilization of slags and their thermal energy. In this paper, with ferronickel slags and blast furnace slags as the main raw materials, glass ceramics ...

Davisite, CaScAlSiO_6, a new pyroxene from the Allende meteorite [PDF]
, 2009 Davisite, ideally CaScAlSiO_6, is a new member of the Ca clinopyroxene group, where Sc^(3+) is dominant in the M1 site. It occurs as micro-sized crystals along with perovskite and spinel in an ultra-refractory inclusion from the Allende meteorite.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

The Effects of Carbonate Precipitation on the Physical Properties of Basalt
AGU Advances, Volume 7, Issue 2, April 2026.Abstract To avoid the negative consequences of climate change, there is an urgent need to remove carbon dioxide from the atmosphere. Carbon mineralization—the conversion of injected CO2 into stable carbonate minerals—offers a promising pathway for large‐scale, permanent geologic storage. While projects such as CarbFix have demonstrated its feasibility,

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The Wyoming Craton is often cited as an example of decratonization, implying the removal of its lithospheric keel. However, numerous geophysical imaging studies indicate the presence of thick mantle lithosphere beneath much of the Wyoming Craton.

Reflectance spectra of Mesosiderites: Implications for asteroid 4 Vesta [PDF]
, 2007 Oxygen isotopic data argues that HEDs and mesosiderites may be from the same parent body. A spectral survey of mesosiderites was done to determine their spectral properties in the visible and near-infrared and compare to ...
