Granitic pegmatite veins occur in clusters at distances of 0–5000 m from the Ke’eryin rock mass, and these veins show horizontal and vertical compositional zoning, In the horizontal direction, outwards from the granitic body, the following are successively exposed: (I) a microcline pegmatite zone (0–800 m from the Ke’eryin rock mass), (II) a microcline albite pegmatite zone (800–1500 m), (III) an albite pegmatite zone (1500–2300 m), (IV) an albite spodumene pegmatite zone (2300–5000 m), and (V) lepidolite pegmatite veins and quartz veins (>5000 m).
The deposit is a Li-Cs-Ta (LCT) [18] spodumene-type pegmatite deposit with proven Li2O resources of 512,185 tons and 15 orebodies in total. Generally, the length of individual orebodies ranges from 220 to 500 m, with a maximum of 2200 m; the thickness of orebodies is typically 5–10 m, up to 124 m. The orebodies are typically in the form of regular veins. Some are lenticular or layered and occur within pegmatite veins with medium length and greater thickness. The internal structure of the ore body does not exhibit distinct zonation, and there is a gradual transition between the ore-rich and ore-poor sections. Over 95% of rare metal ores are of the albite spodumene granite pegmatite type, with the remaining 5% being the albite lepidolite granite pegmatite type.
