AN id=EnChDivSummary name="EnDivSummary">Siwangping copper deposit in Chaoan County, Guangdong Province, is characterized by post-magmatic hydrothermal metasomatism-filling mineralization. Starting with comprehensively studying the data of the deposit, the paper thoroughly analyzed magmatic rocks, fracture belts and trapping condition of surrounding rocks in relation to scale and enrichment degree of ore veins, being aimed to establish an ore-controlling fracture model of the post-volcanic hydrothermal deposit and to offer a theoretical guidance for prospecting deposits of this type in the volcanic rock areas of eastern Guangdong Province based on the thorough analysis on geological environment and genesis of the deposit.
