Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane [PDF]

, 2015
The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand collision process is a Middle?

Geochronology of sillimanite-cordierite gneiss Atamanovo series of the South Yenisei Ridge (Russia)

Литосфера, 2017
The paper provides justification of Paleo Archaean age (3221 ± 15 Ma) of the granulite plutonic metamorphism that formed the Kan metamorphic complex of the Archaean crust in the Angara-Kan block of the Siberian craton. The age was defined on the basis of

Catalysts for change: Museum gardens in a planetary emergency

PLANTS, PEOPLE, PLANET, EarlyView.
Natural history museums are often seen as places with indoor galleries full of dry‐dusty specimens, usually of animals. But if they have gardens associated with them, museums can use living plants to create narratives that link outside spaces to inside galleries, bringing to life the challenges facing biodiversity.

Phase equilibria modelling and geochemistry of high‐grade gneiss from the Chhotanagpur Granite Gneiss Complex, eastern India: Implications for tectono‐metamorphic evolution

Geosystems and Geoenvironment, 2022
We investigated high-grade gneiss from the Daltonganj region of the Chhotanagpur Granite Gneiss Complex (CGGC) in eastern India. EPMA monazite dating from the Daltonganj region revealed three age domains at ca. 1434, ca. 978, and ca.

Metals' Adsorption Onto Environmental Microplastics at Shoreline Sediments

X-Ray Spectrometry, EarlyView.
ABSTRACT This study assessed trace element concentrations and microplastic (MP) contamination in three sandy beaches on the southern coast of Ilha Grande (Rio de Janeiro, Brazil). Environmental MPs were manually extracted from sand samples, and beaches were classified using the microplastic pollution index (MPPI).

Eye makeup in Northwestern Iran at the time of the Assyrian Empire: a new kohl recipe based on manganese and graphite from Kani Koter (Iron Age III)

Archaeometry, EarlyView.
Abstract Kohl was ubiquitous in ancient Egypt and the Middle East, and routinely included among the toiletries deposited in burials. For Egypt, kohl recipes are increasingly well‐studied and known to use a range of inorganic and organic ingredients. Although these are often lead‐based, manganese‐ and silicon‐rich compounds are also attested.
