چکیده انگلیسی
The aims of our study are detailed spectroscopic investigations of sarcopside and graftonite from the MichaÅkowa site combined with precise chemical analyses. The authors provide a full spectroscopic characterization of these minerals in the ranges from 1400 to 400Â cmâ1 - IR investigations and from 1300 to 250Â cmâ1 - Raman investigations. Spectra of pure sarcopside, pure graftonite and mixture of these minerals are compiled. The results show that Raman microspectroscopy allows discerning sarcopside from graftonite in an easy, non-destructive and fast way. Micro-Raman method is proper to distinguish phases in solid solutions as it allows discerning end-members basing on shifted bands in a spectrum. Spectroscopic characterization is also useful in investigation of the presence of H2O and OH molecules in structure of studied phosphates. Increased content of such molecules can confirm a higher level of phosphate alterations.
