Raman Study of the Slobodka Ordinary Chondrite

open access: yesJournal 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

open access: yesJournal 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.

Low‐Frequency Raman Spectra of Natural Pyrrhotites: Polarization Dependence for Its Lattice Modes

open access: yesJournal of Raman Spectroscopy, EarlyView.
The present study found low‐wavenumber Raman modes of pyrrhotite Fe1‐xS at ~68, ~87, ~117, and ~230 cm−1 for the first time, thanks to a lab‐built Raman spectrometer, in which the optical path of the incident laser was purged by Ar gas. The sufficiently high signal‐to‐noise and signal‐to‐base ratios enabled us to obtain the polarization dependence of ...
