Archaeometry, EarlyView.ABSTRACT This study investigates technological evolution in 16th–18th century Catalan tin glazes and cobalt blue decorations. Analysis reveals three glaze strategies, highlighting shifts in tin oxide use and cobalt pigment composition. In the 16th century, tin oxide acted as an opacifier and cobalt pigments exhibit low arsenic content with CoO/NiO and ...

Analysis of pyroxene absorptions observed in Martian dark regions [PDF]
, 1993 We have investigated the mineralogy of the Martian dark regions by analysis of the pyroxene Fe(2+) absorption band near 1.0 micron in a set of VIS/NIR reflectance spectral images.

In situ cosmogenic ¹⁰Be in pyroxene with an application to surface exposure dating
, 2015 Cosmogenic nuclides are an important tool in quantifying many Earth-surface processes. Beryllium-10 (¹⁰Be) is commonly extracted out of the mineral quartz; however many landscapes lack quartz bearing rocks.

Coloration Technology, EarlyView.Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Geostandards and Geoanalytical Research, EarlyView.Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.

Applied SciencesThis study presents the first detailed investigation of pyroxene zoning within polymetallic skarn zones of the Elazığ region. Skarns develop along contacts between plutonic rocks (diorite and granite) and carbonate rocks, forming two main zones ...

P‐T Uncertainty in Subsolidus Metamorphic Systems: Sources, Patterns and Controls
Journal of Metamorphic Geology, EarlyView.ABSTRACT Phase equilibrium modelling of metamorphic rocks is subject to multiple, superimposed sources of uncertainty that affect pressure–temperature (P$$ P $$‐T$$ T $$) estimates, making it difficult to independently distinguish and evaluate the contribution of each source.

Biotite composition constrains Tongling skarn Cu–Au mineralization, eastern China
Solid Earth SciencesSkarn Cu, Au deposits are most important deposit-type in the Tongling region, eastern China, where skarn Au deposits are closely associated with pyroxene monzodiorite, and skarn Cu deposits are genetically related to quartz monzodiorite and granodiorite.

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids
Meteoritics &Planetary Science, EarlyView.Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...
