Abstract

Dunje i Čanište pegmatitska su ležišta nastala u Pelagonijskom masivu Sjeverne Makedonije. Na lokalitetima je pronađen mineral epidota. Uzorci sa lokaliteta Dunje su epidot kemijske formule: (Ca1.84-1.92 )(Fe0.71-0.83 Al2.15-2.18)(SiO4 Si2O7)O(OH) te parametara jedinične ćelije: a= 8.8870(4) Å, b=5.6291(4) Å, c=10.1505(4) Å, β =115.34(2)° i V=458.93(2) Å3. Kristali pokazuju zonalnost okomito na kristalografsku os b. Nastali su iz kiselije magme te umjereno slanih fluida 17,05 wt. % NaCl eq. Uzorci sa lokaliteta Čanište su epidot kemijske formule: (Ca1.83-1.90)(Fe0.72-0.75 Al2.15-2.30)(SiO4 Si2O7)O(OH), te parametara jedinične čelije: a=8.9014(3) Å, b=5.6135(4) Å, c=10.1540(4) Å, β =115.423(3)° i V=458.24(2) Å3. Nastali su iz bazičnije magme te umjereno slanih fluida 8,22 wt. % NaCl eq.

Abstract (english)

Dunje and Čanište are pegmatite deposits in Pelagonian masiff of North Macedonia. Epidote crystals are found on the localties. Samples from Dunje locality are epidote of chemical formula: (Ca1.84-1.92 )(Fe0.71-0.83 Al2.15-2.18)(SiO4 Si2O7)O(OH) and unite cell parameters: a= 8.8870(4) Å, b=5.6291(4) Å, c=10.1505(4) Å, β =115.34(2)° i V=458.93(2) Å3. Crystals show zoning vertical on axis b. They originated from more acidic magma and moderately saline fluids 17,05 wt. % NaCl eq. Samples from Čanište locality are epidote of chemical formula: (Ca1.83-1.90)(Fe0.72-0.75 Al2.15-2.30)(SiO4 Si2O7)O(OH) and unit cell parameters: a=8.9014(3) Å, b=5.6135(4) Å, c=10.1540(4) Å, β =115.423(3)° i V=458.24(2) Å3. They originated from more mafic magma and moderately saline fluids 8,22 wt. % NaCl eq.
