New investigations on Dunje pegmatite, Macedonia I: the contribution to the knowledge about alkali feldspars and its mineral paragenesis

Selečka Mountain was thoroughly investigated in the past mostly because of the interesting mineral paragenesis presented in granites, gneisses, amphibolites, different schists and pegmatite bodies. In the valley Smilevski Dol, around 3 km SW from the village of Dunje (Mariovo plateau), in the vicinity of small spring Šohlehov Kladenec hydrothermal pegmatite vein was found containing well-formed crystals of albite, microcline, amphibole, epidote, titanite, quartz, muscovite, chlorite, stilbite, heulandite, pyrite, apatite and rutile. Recent investigations brought out some more information about morphological and chemical characteristics of feldspars, namely albite and microcline and their oriented growth and confirmed garnet as new mineral in the paragenesis.
