Redox states of thirteen shergottites as inferred from iron micro X-ray absorption near edge structure of maskelynite
shergottite X-ray Absorption Near Edge Structure Mars maskelynite redox stat
2017/4/10
We used synchrotron radiation Fe micro-XANES (X-ray Absorption Near Edge Structure) analysis to determine the
iron valence of maskelynite (shocked-plagioclase glass) in thirteen shergottites, and we ...
Determination of the host phase of rare earth elements in natural carbonate using X-ray absorption near-edge structure
