Abstract
Detail study on carbonate-type ores in the Shuiyindong gold deposit shows that auriferous pyrite is characterized by three-floor pattern,the gold is hosted in arsenic-bearing pyrite zone generating along hypidiomorphic and automorphic sedimentary pyrite kernel,which high content amount to 600×10-6~1800×10-6 in arsenic-bearing pyrite zone is in content equivalent to arsenic of 3 to 6 percent,antimony of 0.025 to 0.075 percent,copper of 0.025 to 0.075 percent and sulfide of 48 to 53 percent.Thallium content is lower than detection limit that is not obviously related to gold mineralization
