In situ and micro‐Raman spectroscopy for the identification of natural Sicilian zeolites

Zeolites are present in numerous outcrops of volcanites different ages Sicily (Italy). Some these important because they constitute the ideal genesis conditions some minerals, which represent geological indicators chemical and geothermal gradients involved during their formation. For this purpose, a group zeolites coming from areas Ionian coast Palagonia village (Eastern Sicily) was investigated by means Raman spectroscopy. In record, have been influenced intense volcanic events that produced mineralization hydrothermal origin. Sicilian zeolite samples were analysed situ using mobile apparatus, directly on Aci Castello nearby Lachea Island, or local collections where preserved. then laboratory micro-Raman to compare results identify types. The strength weakness points each instrument highlighted. Often, spectra affected broad fluorescence, making them difficult interpretation. However, satisfying obtained with portable devices, whose identifications confirmed micro-Raman, discerning groups, such as analcime, chabazite, natrolite phillipsite. use instruments has demonstrated possibility obtain identification related minerals both site laboratory, match setting considered areas.
