Abstract：The skarn type of copper-gold deposit occured in the contact zone of Salakoukeshen granitoid complex and Lower Cambrian Series volcanic sedimentary rock. Hydrothermal gold mineralization(360-130℃)mostly superimposed on skarn rock(400℃).Gold mineralization mostly distributed in garnet-wollastonite skarn rock.Oxidation resulted enrichment of secondary sulphide and the reducing of native gold,the reason for the latter was that the gold is more active than silver.At the same time,part of silver seperated out from native gold during oxidation,so the fractional percentage points of gold is similar to native gold in endogenetic ore;Because of the fractional percentage points of native gold in oxidized zone has widly discretation, we should pay more attention to it in evaluating deep seated ore.
