Figure7

Conceptual sketches of craton formation. Grey arrows show sense of motion. Red arrows indicate melt transport. (A) Melting event trigger by large mantle plume as described in Pearson et al. (1995) and Lee et al. (2011). (B) Burial/reworking and sorting of dense materials (e.g., Robin and Bailey, 2009, Moore and Webb, 2013 and Sizova et al., 2015). Though not explicitly shown in this sketch, diapirism can further aid the resorting of dense materials. (C) Lithospheric thickening through the amalgamation of arc material (e.g., Jordan, 1978). (D) Thrust stacking and imbrication of buoyant oceanic lithosphere (e.g., Bostock, 1998).
