Various published models for the growth of continental crust: HR67 [13], F78 [22], B79 [23], A81 [24], MT82 [25], RS84 [26], AR84 [16], ND85 [27], PA86 [28], J88 [29], W89 [30], CK99 [31], C03 [32], R04 [33], CA10 [34], B10 [35], D12 [11], K18 [36] and RK18 [37]. The volume or mass of the continental crust is normalized by the present-day value. Line colours are assigned to produce gradations from blue to red across the models; each model retains its line colour in figures 2, 3 and 6.
