资源简介：
Sample SB171122-3C is a coarse-grained granitic rock (metamorphic melt) within migmatitic gneiss of Mt. Murchison. Since metamorphic age of other three samples in the same outcrop is confirmed as 498.3 ± 3.4 Ma, formation age of this sample could be synchronous with the metamorphic (migmatization) age.
