摘要
Multiple stratigraphic division and correlation sequence has been improved during 1∶50 000 regional geological survey in Meizhou, eastern Guangdong Province. The volcanic facies, volcanic apparatus and volcanic activity cycles are identified by dual mapping method. Intrusive rocks of survey area are re-studied, and the Yonghebei-Sanfeng intrusion is divided into ultramafic, intermediate and acid intrusive rocks at the first time. Structural feature of Jiulongzhang multiple syncline and Lianhuashan faulted zone are found out. Metallogenic regularity of survey area is summarized by various exploration methods, such as stream sediment survey.
