Summary

A hitherto unknown TI-sulfosalt, containing antimony and arsenic, was discovered by ore microscopy (including quantitative reflectance measurements) and electron microprobe analysis in samples from the Allchar TI-Sb-As sulfide ore deposit (Macedonia). The chemical formula is TI5Sb9(As,Sb)4S22, X-ray single crystal and powder diffration data gave the lattice parametersαo = 7.393(4) Å, b0 = 8.707(2) Å, co = 17.584(3) Å,α = 103.81(1)°,β = 91.79(1)°,γ = 109.50(1)°; space group\(P\bar 1\), Z = 1. The new mineral and the new mineral naine “jankoviéite” have been approved by the IMA/CNMMN.

Jankovićit, Tl5Sb9(As,Sb)4S22, ein neues TI-Sulfosalz aus Allehar, Macedonien

Zusammenfassung

Ein bislang unbekanntes Thallium-Antimon-Arsen-Sulfosalz wurde mittels Erzmikroskopie (inklusive quantitativer Reflexionsmessungen) und Elektronenstrahl-Mikrosonde in Proben aus der TI-Sb-As-Sulfid-Lagerstätte Allchar in Macedonien entdeckt. Die chemische Formel lautet Tl5Sb9(As,Sb)4S22, aus Röntgen-Einkristallaufnahmen und Pulverdiffraktogrammen konnten folgende Gitterkonstanten bestimmt werden: ao = 7.393(4) Å, bo = 8.707(2) _Å, co = 17.584(3) Å, a = 103.81(1)°, β = 91.79(1)°, γ = 109.50(1)°; Raumgruppe\(P\bar 1\), Z = 1. Das neue Mineral, sowie der neue Mineralname “Jankovićit” wurden durch die IMA/CNMMN anerkannt.
