///The Xiaobaishitou biotite-granite pluton is situated in the southeastern margin of the central Tianahan block. LA-ICP-MS U-Pb isotopic dating for zircon separated from the rock yields an average ²⁰⁶Pb/²³⁸U age of (322±5)　Ma.　Geochemical analysis in the major element, trace element and REE the intrusion indicates that this granite is rich. The geochemical dating of the granite yields characteristics similar to those VAG, inheriting the characteristics of its original rock. This study suggests that the original rock of the biotite-granite is metamorphic greywacke.
