From the samples of soil in Anba ore block of Yangshan gold deposit��we separated and extracted the eight forms (free state��sulfide bound��organic matter bound��carbonate bound��Fe-Mn oxide bound��water- soluble��exchangeable and residual form) of gold��analyzed the contents of the eight forms of gold by the GFAAS�� and found out their distributions�� The results show that gold mainly existed in free state��sulfide bound and organic matter bound��which are 3. 3% ��75. 9%��0 ��37%��3. 3% ��26%��in percentage of the whole contents��respec- tively��and the average content of gold is 105. 5 ×10��9��30. 5 ×10��9��25. 3 ×10��9��accordingly�� The peak of the relative content for free state and the minimum of the relative content for mobile forms both come above the ore-body indicating where the ore-body exists�� Therefore��we can use the gold in the free state or mobile forms as the key to search the carlin-like deposits��
