Outcropping area is about 30 km2.
There are three types of mineralization in the Lalong Dome: albite granite-type Be–Nb–Ta rare metal mineralization, skarn-type Be–Nb–Ta rare metal mineralization, and hydrothermal structure-type W–Pb–Zn polymetallic mineralization. Albite granite-type Be–Nb–Ta rare metal mineralization is the focus of this contribution, and the other two types of mineralization will be reported in other papers. Lalong albite granite-type Be–Nb–Ta rare metal mineralization is mainly hosted by albite granite and pegmatite. The controlled strike length of the rare metal ore bodies is ca. 1500 m. The average thickness of orebody is 5 m, the average grades of BeO, Rb2O, Nb2O5, and Ta2O5 are 0.0785%, 0.0556%, 0.0087%, 0.0208%, respectively. The ore structure is generally a massive structure, and the ore texture is mostly euhedral–granular and metasomatic. The main rare metal minerals are columbite, tantalite, pyrochlore, teshirogilite, tapiolite, beryl, uraninite, microlite, Nb-Ta-bearing rutile, and fergusonite. In addition, molybdenite is mainly scattered in pegmatite. The main gangue minerals are quartz, albite, K-feldspar, muscovite, with minor garnet, tourmaline, and biotite. Both the albitization and greisenization occur in the Lalong albite granite-type rare metal deposit.
