Microbeam X-ray analysis of Ce3+/Ce4+ in Ti-rich minerals: A case study with titanite (sphene) with implications for multivalent trace element substitution in minerals

Abstract

Cerium L3 absorption edge (L3-edge) X-ray absorption near edge structure (XANES) spectra were obtained from ∼7 × 5 μm areas on green titanite and brown titanite (both with total Ce ∼ 0.6 wt%) using the X-ray microprobe at the Pacific Northwest Conso Show more
