Abstract: On the basis of detailed geological investigation and mapping, this paper studies the petrological features of Shiling alkaline complex, Conghua, Guangdong Province. Which is mainly composed of nepheline-hornblende syenite, hornblende syenite and biotite syenite. The alkaline complex is formed by granite fractionation, occurs in intraplate extensional tectonic setting and is related to deep fault. It is significant that the complex itself is a nepheline syenite mineral deposit of industrial and economic values.
