Název v původním jazyce

Enargite, tennantite-(Cu) and tangdanite from the Gápeľ copper deposit near Dobšiná, Spišsko-gemerské rudohorie Mts., Slovakia

Popis výsledku v původním jazyce

A new occurrence of enargite, tennantite-(Cu) and tangdanite was recently discovered at the Gápeľ copper deposit near Dobšiná, Spišsko-gemerské rudohorie Mts., Rožňava Co., Košice Region, Slovakia. Enargite is rare mineral at the studied locality and it occurs as dark-grey, metallic, prismatic crystals up 2.5 mm with perfect cleavage, developed on fractures of quartz-dolomite gangue. Its refined unit-cell parameters (for the orthorhombic space group Pmn21) are: a 7.4031(7) Å, b 6.4321(6) Å, c 6.1466(7) Å and V 292.68(4) Å3. Its chemical composition corresponds to empirical formula Cu3.04As0.98S3.98. Tennantite-(Cu) forms anhedral grains and aggregates replacing crystals of enargite. Its empirical formula is Cu6.00[Cu4.00(Cu1.07Fe0.64Zn0.42)Σ2.13]As3.87S13.04. Tangdanite occurs as turquoise-blue to blue-green radial aggregates up to 3 mm with silky lustre, developed on fractures of quartz gangue with partly weathered aggregates of minerals of the tennantite series. Its chemical composition corresponds to empirical formula Ca2.12(Cu8.77Zn0.19)8.96[(AsO4)3.91(PO4)0.08(SiO2)0.01]4.00(SO4)0.43(OH)9.30.9H2O.
