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.

Integration of Physics‐Based and Data‐Driven Approaches for Landslide Susceptibility Assessment

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Rainfall‐triggered landslides pose a significant threat to communities and infrastructure around the world. Various data‐driven and machine learning (ML) based algorithms have been applied to assess landslide susceptibility. However, purely data‐driven methods are affected by issues such as uncertainty in the selection of landslide ...

Neoproterozoic ultramafic and mafic magmatism in the Eastern Cordillera of the central peruvian Andes: the Tapo Massif [PDF]

, 2010
A highly dismembered assemblage of ultramafic and mafic rocks is exposed in the Eastern Cordillera of the Central Peruvian Andes, extending along a discontinuous NW-SE belt over some 250 km between 12° and 9° S of latitude.

Passiflora quimiana, a new species from the Cordillera del Cóndor: Ecuador's far‐flung frontier

Nordic Journal of Botany, EarlyView.
A new species of Passiflora subgenus Decaloba, supersect. Decaloba, from the Cordillera del Cóndor in Ecuador, is described and illustrated, with its morphological similarities to other species being discussed in this paper. Passiflora quimiana exhibits the unique combination of narrow ovate to long‐oval leaves and small foliaceous bracts ...

U-Pb SHRIMP zircon dating of Grenvillian metamorphism in Western Sierras Pampeanas (Argentina) : correlation with the Arequipa-Antofalla craton and constraints on the extent of the Precordillera Terrane [PDF]

, 2006
The Sierras Pampeanas of Argentina, the largest outcrop of pre-Andean crystalline basement in southern South America, resulted from plate interactions along the proto-Andean margin of Gondwana, from as early as Mesoproterozoic to Late Paleozoic times (e ...

The women honoured in flowering plant genera: From myth to reality

PLANTS, PEOPLE, PLANET, EarlyView.
Many flowering plant genera are named for people, but there is a gender gap in this naming, with only 6% of eponyms honouring women. Here we explore this gap by examining in detail women for whom plant genera are named. Our open shared dataset serves to make women honoured in plant genera more discoverable, resulting in further impact by allowing ...

The Gold‐Maker of Animal Oil and Prussian Blue Fame — The Chemical and Medicinal Science Philosophy of Johann Conrad Dippel

The Chemical Record, EarlyView.
The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...
