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.
