Photomicrographs and Raman spectra of melt inclusions. a Secondary mineral inclusions trail hosted by titanite in sample IJ-9/4 showing calcite. b Melt inclusions in titanite in IJ-9/4 showing the presence of calcite in glass and graphite in shrinkage bubble (Asterisks show the Raman peaks of host titanite). c Calcite and apatite in melt inclusions hosted by clinopyroxene in IJ-9/4. d Presence of rutile in mineral inclusions hosted by clinopyroxene in IJ-9/2. e, f and g Melt inclusions hosted by clinopyroxene in IJ-9/2, IJ-11/1, and IJ-11/2 showing the presence of calcite in Raman spectrum. h Aphthitalite and CO2 in melt inclusions. [All the Raman spectra show Raman shift (cm−1) on x-axis and Intensity (cnt) on y-axis.] Orange circles around the inclusions show mineral inclusions, while the rest of all are the melt inclusions.
