The redox of alkaline-earth silicates with iron concentrations ranging from 150 to 5000ppm was measured using X-ray absorption spectroscopy at the K-edge of iron, in fluorescence mode. These measurements were carried out at three beam lines with different characteristics: FAME (BM30) and DUBBLE (BM26) at ESRF (Grenoble, France) and XAFS2 at LNLS (Campinas, Brazil). In those conducted at BM26, we observed...
Microprobe monazite dating has been increasingly used to constrain the timing of deformation and metamorphism because of the potential to date very small monazite domains (down to 5 μm or less) in structural and petrologic context. This paper presents an analytical strategy, presentation format, and error considerations for microprobe monazite dating. The strategy involves high-resolution compositional...
