Recipe Details
Ingredients
Lazurite, Calcite, Pyrite, Hematite, Sodalite, Diopside, Wollastonite
Preparation Steps
Identified by SSE Raman bands at 544, 584, and 808 cm-1 representing signals from admixtures in the rock. FORS spectra show reflectance maximum/minimum at 474 and 600 nm and IP at 714 nm (Table 2).

Evidence
"SSE Raman (b) spectra recorded on blue areas of MEK-MS-6LP. (La): Lazurite, (Ca): Calcite, (Py): Pyrite, (He): Hematite, (So) Sodalite, (Di): Diopside and (Wo): Wollastonite."
Remarks
Found in blue areas of MEK-MS-6LP. XRF efficiency was poor for this material (Table 2).
