海洋山花岗岩体位于华南加里东花岗岩带内。岩体中岩石具有较低的应变结构；奥陶系围岩受到的变形变质作用较低，但作用时间较长。各种构造型式表明：该岩体的侵位机制是以同构造穹窿为主，并兼具有某些气球膨胀特征。
Ocean Hill granite body is located in South China Caledonian granite belt. The rocks in the rock mass have a lower strain structure. The Ordovician rock mass has lower deformation and metamorphism, but its action time is longer. Various structural types show that the emplacement mechanism of this rock mass is dominated by domes with the same structure with certain balloon expansion characteristics.
