摘　　要：The global collisional orogenic events (e.g. Grenvil-lian or Pan-African event) have occurred for several times since 2.5 billion years (Ga) ago, which has led Earth scientists to speculate that continental landmasses have periodically assembled and dispersed, resulting in the assembly and breakup of supercontinent. In the last decade, the reconstruction of ancient supercontinents has been focused on Rodinia, a defined supercontinent that was assembled along the -1.0 Ga "Grenvillian" oro-gens. In reconstructing Rodinia, however, Earth scientists have noticed that not all continental blocks in the supercontinent were welded by the -1.0 Ga orogenic belts (fig. 1(a)), and that most blocks welded by the 1.0 Ga orogens contain abundant evidence that they are a
