New achievements in the mineral studies by use of the Raman microspectroscopy

By the means of the technique of the Raman microspectrometry, the complex history of the Earth can be better understood. That is why the Raman spectra determinations are the object of interest in the present paper. The examples of such experiments are presented based on the analyses performed in last years in different scientific centers (Potsdam, Banská Bystrica, Budapest). The identification of inclusion content is shown and the conclusions are drawn for fluid inclusions in some quartz samples from two different localities in Poland – in the Carpathians and in the Fore-Sudetic Block. The implications of the Raman analyses are discussed. It results from the Raman analyses performed that not fluorescing, gas-filled bubbles of huge fluid inclusions from the Jabłonki and Rabe vicinity (the tectonic mélange zone in the Carpathians) have the complex composition of CH4, CO2 and N2 in different mutual proportions dependent on the sample and locality. In another place, despite the fluorescing background, only methane has been identified by Raman spectra. Similar gas composition was determined in the inclusions in the vein quartz in the Wądroże Wielkie area (the Fore-Sudetic Block).
