Sm-Nd isochron diagram for Venetia garnet inclusions. The two isochrons are distinguished based on T DM and CaO of the samples. Green square symbols represent the 3.0 Ga age group samples with lower than 2.5 wt.% CaO; blue triangles represent the 1.1 Ga age group with higher than 2.5 wt.% CaO. The analytical errors are smaller than symbol sizes.
