• Description: Ba-feldspars of pyrrhotite ore from Bušín in Zábřeh unit were studied. Ba-rich feldspars form grains and porphyroblasts in pyrrhotite ore. According to WDX-analyses there are older celsiane (with 85-95 mol.% of celsiane endmember) and younger hyalophane (with 29-55 mol.% of celsiane endmember). It indicates two metamorphic stages of ore protolith formation.
