The HREE mineralization locally occurs in the weathering profile of the two-mica granite.
The main REE ore-forming parent rock in the region is the Dabu granitic pluton, which occurs in a batholith with an outcrop area of 515 km2. The Dabu batholith is a multistage complex pluton that was first formed during the Caledonian stage, with a zircon U–Pb age of 393 ± 27 Ma. However, the main part of the Dabu pluton was formed in the early Yanshanian period (161–169 Ma).
A horizon: This layer is yellowish-brown with strong cohesiveness and is mainly composed of clays and quartz at depths of 0–4 m. B horizon: This layer commonly appears light flesh-red with a loose structure, and the content of residual feldspar is noticeably increased at depths of 4–20 m. C horizon: This layer gradually transitions from the B horizon without a distinct boundary. It typically maintains a dense granite structure at depths of 20–24 m. P horizon: Fresh granite at a depth of 27 m.
