Ifl›k Da¤› (K›z›lcahamam-Ankara) Yak›n›nda Bulunan Bulanjerit, Jeokronit ve Yenerit ‹le ‹lgili Bir Mineralojik Not

Mikroprob çal›flmalar›n›n yard›m›yla, Ifl›k Da¤› (Ankara, Türkiye) yak›n›nda bulunan jeokronitin varl›¤› ilk kez saptanm›flt›r. Yenerit, PbS-Sb2S3 bileflimsel çizgisi üzerinde ayr› bir mineral türü olarak kabul edilemezse bile, orijinal analizlerin gösterdi¤i gibi bu çal›flmada sunulan analizler de arsenik elementinin önemli miktarda var oldu¤unu göstermektedir. Dolay›s›yla arsenikçe zengin bulanjeritler için yenerit ad› tavsiye edilebilmektedir.

A Mineralogical Note on Boulangerite, Geocronite and Yenerite From Near Ifl›k Da¤› (K›z›lcahamam-Ankara), Turkey

Microprobe studies have facilitated recognition of the first documented occurrence of geocronite from Işık Dağı (Ankara, Turkey). While yenerite remains a discredited species along the PbS-Sb2S3 compositional join, our analyses show significant arsenic as did the original analyses for yenerite; thus, this name might be retained for arsenic-bearing varieties of boulangerite.
