对广东从化石岭碱性杂岩体进行了１∶１万地质调查和填图，并进行了详细的岩石学研究。其结果表明：杂岩体由霞石角闪石正长岩、角闪石正长岩、黑云母正长岩等岩性组成，为Ａ－型花岗岩的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。
A 1: 10000 geological survey and mapping of fossil basement complex in Guangdong Province were carried out and detailed petrological studies were carried out. The results show that the complex bodies are composed of lithic syenite, amphibole syenite and biotite syenite, which are formed by the differentiation crystallization of A-type granites. Within the extension of the structural environment, and the deep fault related. The rock mass itself has formed nepheline syenite deposit, which has high industrial utilization and economic value.
