Revisiting the Jurassic Geomagnetic Reversal recorded in the Lesotho Basalt (Southern Africa)

, 2003
We carried out a detailed and continuous paleomagnetic sampling of the reversed to normal geomagnetic transition recorded by some 60 consecutive flow units near the base of the Lesotho Basalt (183  1 Ma).

Liebig Review: Legume–Rhizobium Symbiosis Under Selenium Fertilization: A Unique Dual Function in the Plant–Soil System

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Selenium (Se) plays a vital role as a beneficial element in promoting the production of leguminous plants. It influences legume quality by improving crop nutritive value and contributing to human and animal health. Literature Review This review is timely, as there are gaps in understanding Se–rhizobia interactions in legumes, which ...

Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England

Journal of Quaternary Science, EarlyView.
ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,

Raman Analysis of Roman Mosaics From the Upper Guadalquivir Valley (Spain)

Journal of Raman Spectroscopy, EarlyView.
This work is focused on the Raman analysis of two Roman mosaics from Jaén (Spain) using portable and benchtop equipment, complemented by elemental analysis using EDXRF and petrographic analysis. The results obtained have provided a detailed characterisation of the tesserae.

Thermally Optimised Raman Spectroscopy for Safe Analysis of Wall Paintings and Application to Lorenzetti's Masterpiece

Journal of Raman Spectroscopy, EarlyView.
A portable dual‐wavelength Raman system (exc. 785 and 1064 nm) based on a four‐channel innovative probe for safe characterisation of artworks is presented. This instrument enables non‐contact real‐time monitoring of the temperature rise and laser power modulation to prevent overheating during Raman spectroscopy, through direct emissivity and ...

Raman Study of the Slobodka Ordinary Chondrite

Journal of Raman Spectroscopy, EarlyView.
The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.

Assessing Thermal Maturity of the Pendência Formation (Potiguar Basin) Using Vitrinite Reflectance and Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Palynofacies assemblages from the onshore Potiguar Basin display a wide thermal maturity range, with vitrinite reflectance (%Ro) values of 0.46–2.72 measured from nine samples at depths of 1059–4443 m. A strong correlation exists between %Ro and Raman parameters, specifically the G‐band's full width at half maximum.
