Structural state of native molybdenum in the lunar regolith

Laser Raman micro-spectroscopy as an effective non-destructive method of detection and identification of various sp2 carbon modifications in industry and in nature

“…The BSE image has revealed that the crust consists of two parts: an internal molybdenium one and an external carbon-rich inclusion. However, the nature of carbonaceous substance detected in the paper [93] could not be elucidated by the methods applied in the study. We have investigated by Raman micro-mapping about 20 fragments of ~50×50 µm size of the Lunar soil probes described in Ref.…”

“…Some fragments of lunar soil extracted by the Russian automatic station "Luna-24" from a deep part of the core in Mare Crisium (at a depth of 1.85 m) were investigated previously by the energy-dispersive X-ray analysis, SEM and back-scattered electron diffraction (BSE) [92,93]. The results have shown that the crust of a large glass splinter contained the peaks of molybdenium, carbon, and oxygen.…”

“…We have investigated by Raman micro-mapping about 20 fragments of ~50×50 µm size of the Lunar soil probes described in Ref. [92,93]. Many spectra obtained contain only the features of the minerals present.…”
