Phosphates are a group of complex minerals widespread on Earth that can crystallize in several environments. Changes in environmental conditions during crystallization are reflected in the formation of a sequence of phosphate minerals, termed paragenesis. Accordingly, analyses of textural and chemical properties of complex mineral assemblages are essential to reconstruct the history of rocks and solid...
The nondestructive micro‐Raman technique and the infrared spectroscopy are used to investigate sincosite mineral. Sincosite [Ca (VO)2(PO4)2·4H2O] exhibits the characteristic vibrational modes of PO4 tetrahedra, V(O,H2O)6 octahedra, H2O groups, and further external modes. The PO4 Raman and infrared stretching and bending vibrations of sincosite occur between 1,200 and 900 cm−1 and between 600 and 400...
