A mineralogical note on boulangerite, geocronite and yenerite from near Işık Dağı Kızılcahamam-Ankara), Turkey

Mikroprob çalışmalarının yardımıyla, Işık Dağı (Ankara, Türkiye) yakınında bulunan jeokronitin varlığı ilk kez saptanmıştır. Yenerit, PbS-Sb2S3 bileşimsel çizgisi üzerinde ayrı bir mineral türü olarak kabul edilemezse bile, orijinal analizlerin gösterdiği gibi bu çalışmada sunulan analizler de arsenik elementinin önemli miktarda var olduğunu göstermektedir. Dolayısıyla arsenikçe zengin bulanjeritler için yenerit adı tavsiye edilebilmektedir.

Işık Dağı (Kızılcahamam-Ankara) yakında bulunan bulanjerit, jeokronit ve yenerit ile ilgili bir mineralojik not

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.
