From: Metamorphic turnover at 2 Ga related to two-stage assembly of Columbia
Synoptic reconstruction of the two-stage assembly of Columbia with superimposed orogens and metamorphic rock record at (A) 1.8 Ga and (B) 1.6 Ga. Green and purple stars reflect ophiolite and eclogite relics, respectively, reported by Wan et al.3. Numbered references: (1) Yu et al.65, (2) Kontinen66, (3) Glassley et al.31, and Willigers et al.32, (4) Müller et al.30, (5) Weller and St-Onge33, (6) Scott et al.43, (7) Wan et al.70, (8) Xu et al.69, (9) Gornova and Glazunov68. Red, orange, and blue circles represent the metamorphic rock record between 2.0 and 1.6 Ga as reported in Brown and Johnson71. Small curved black arrow indicates relative motion of the North Australian Craton with respect to Laurentia (see Fig. 2).
