TYPES AND STRUCTURAL CONTROL OF GOLD DEPOSITS IN THE TONGGUANSHAN ORE FIELD,ANHUI PROVINCE

Tongguanshan is a famous copper ore field and one of copper-producing areas of China. Recently a number of gold deposits have been found, which belong to the sulfide type and gossan type and are genetically related to copper deposits in the ore field. The paper mainly deals with the types, geological characteristics and structural controls of gold deposits, The author considers that both the two types of gold deposit belong to the magmatic hydrothermal type genetically related to Yanshanian intermediate and intermediate-acid intrusive rocks, and its outcropping as different types of ore deposit is just due to the differences in oxidation-denudation and preservation conditions. The attitude of gold ore bodies are strictly controlled by that of the strata in different parts of the Tongguanshan overturned anticline and interlayer faults.
