Thin-layered granite residual weathering crusts covered by high mountain sparse bush and meadow in the subnival lake area belong to the alumino-siliceous weakly acid-acid leaching type, with the leaching of Na₂O, CaO, K₂O, SiO₂ in different degrees. Most weathered parent rocks have relatively high trace elements such as B, Bi, Zn, Nb, La, Be, Sr, F and Ag. Al₂O₃ is basically stable, and TFe, MgO, TiO₂, P₂O₅ and TMn have been somewhat accumulated. There are also high contents of Sn, Mo and Zr and low contents of Hg, Cu, Ni, Co and Li in parent rocks.
