Short summary
In the Liaodong Peninsula, the widely exposed Jurassic high-Sr / Y rocks are generally considered to be derived from the thickened mafic crust. However, research on the Zhoujiapuzi granite in this study shows that there is at least one pluton with a high Sr / Y signature inherited from the source. Zircon growth in Zhoujiapuzi granite can be divided into two stages. The light-CL core was formed in a deeper, hotter magma chamber. The dark-CL rim formed from later, more evolved magma.
