摘　　要：广东台山铜鼓黑沙湾因黑沙滩而闻名.野外调查发现,台山铜鼓黑沙湾黑沙滩主要是由片状黑云母引起的.此外,黑沙滩的形成与海岸地貌、海岸基岩的物质组成及其海水动力条件密切相关.It is famous for black-sand beach of Tonggu black-sand bay in Taishan, Guangdong province. Based on the field survey, the authors in this paper think the black-sand beach is mostly caused by biotites, not by polluting from cinders and ashes burned in the thermal Power Plant of Taishan nearby. The formation of the black-sand beach is also closely related to the coastal geomollohic environments, the components of the source rock and the hydrodynamic conditions of seawater on the coast.
