Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...

And then there was us Et puis nous sommes apparus

Journal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

Journal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

Acta Geologica Sinica - English Edition, EarlyView.
High‐grade orebodies are controlled by stress field with σ1 oriented NE‐SW during the main mineralization stage.Inferred NEE‐trending strike‐slip fault control another orebody distribution. ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt.

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

Acta Geologica Sinica - English Edition, EarlyView.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo
