| 摘 要： | 广东石岭碱性杂岩体岩石矿物和岩石化学研究表明，杂岩体以霞石角闪正长岩、角闪正长岩为主，黑云母正长岩等岩石组成，为Ａ－型花岗岩分异结晶作用所形成。产于板内引张构造环境，与深大断裂有关。岩体本身已构成霞石正长岩矿床，具有较高的工业利用和经济价值。

| Abstract: | On the basis of detailed geological investigation and mapping on Shiling alkaline plutonic complex,Conghua,Guangdong Province,this paper studies the petrological features of the complex mainly composed of nepheline hornblende syenite,hornblende syenite and biotite syenite.The alkaline complex was formed from granite fractionation,occuring in intraplate tension setting related to deep fault.It is significant that the complex itself is a nepheline syenite deposit of industrial and economic values. |
