Abstract

Gold as a strategic element has a strong exploration potential in KurdistanCounty. This investigation for gold has carried out in N.W. Sanandaj- Siirjan geological zone. 351 samples has been taken from drainages and analyzed by ICP-MS in Canada for 22 elements. Based on results, anomaly map and enrichment ratio for gold and related paragenetic elements have been prepared.  The result indicate an enrichment factor of 1-99 times for gold and 1-3, 1-19, 1-3, 1-3, 1-6, 1-2, 1-7, and 1-4 for elements Ag, As, Pb, Zn, B, Ba, Bi and W, respectively. Data resulted to a distribution pattern for Au and other elements such as. Gold anomaly is recognize in 36 Km2 associated up to 19 times enrichment for As.  Therefore As is a good indicator element for Au her and in similar environments. Tectonically gold showed a very strong relation with breccias zones and par genetic minerals.
