RAMAN STUDY OF SECONDARY MINERALS IN A RECENT LAVA TUBE

Abstract

International audienceIn this paper, we present first the technical adaptations made for a field use of the laboratory in situ spectrometer, its capabilities and limits as well.Secondly, we present identification of secondary mineral phases growing in the lava tube with a particular emphasis on the study of white speleothems and dendrites by mean of XRD, SEM-EDX and Raman spectroscopy
