The occurrence of Getchellite (AsSbS3) at Zarshuran As - Au
deposit

Abstract: The variety of lithologies from Late Precambrian to
Quaternary and suitable
conditions for mineralization caused formation of Zarshuran gold
and arsenic deposit in black
schists, shale, limestone and dolomite. The ore paragenesis include
As, Sb, Fe, Pb, Zn, Hg
sulfides and gold along with fluorite, barite and quartz. The most
important alteration is
silicification which is more obvious in the ore zone and formed
jasperoid. The gold in this
deposit is found as very fine grains and is rarely visible. The
rare Getchellite occurred in
arsenic ore zone of Zarshuran as a red mineral with (001) cleavage.
Paragenetically, this
mineral is intermediate between As and Sb sulfides. Getchellite
found in some epithermal
gold deposits, can be used as a gold tracer.
Keywords: Getchellite, Epithermal gold deposits, Zarshuran,
Takab.
