Abstract: 

Molybdenite is the main important carrier of Re. There are some hypotheses that the 3R molybdenite polytype could carry more Re in its structure. This study aims to provide initial data for different polytypes of molybdenite from the Panicherevo molybdenum deposit. There is a negative correlation between polytype formation and chemical content. Samples were characterized by means of powder X-ray diffraction and Raman spectrometry in order to reveal the presence of 2H1 and 3R molybdenite polytypes. LA-ICP-MS analyses reveal that, in the 2H1 polytype, trace elements are more abundant than in the 3R polytype.
