Mineralogy and geochemistry of trace elements from Tsrven dol- Alshar deposit (Republic of Macedonia)

The results of new mineralogical study by the X-ray diffractions and the results of the analysis of the trace elements and rare earth elements (REE) in the ore mineralization of Tsrven Dol by the ICP-MS are presented in this paper. Mineralogical study suggested very interesting mineral associations presented by lorandite, realgar, orpiment, vrbaite, bernardite, jankovichite, fangite, rosenite, farmacolite, marcasite, pyrite, sulfur, gypsum, dorallcharite, dolomite, quartz. The content of trace elements and REE in the surrounding rocks and in the ore mineralization suggested the idea of influence of the ultramafic rocks from the western flank of the Vardar zone in the hydrothermal activity in the Alshar deposit, especial y in the ore body Tsrven Dol.
