Fig. 2.22.— Sedimentation rates of platform margins and lagoons in Belize and Florida. Rates of reef rims are 3 to 35 times higher
than the lagoon rates. The difference must reflect higher growth potential of the rim because the lagoons are deep and have unused
accommodation. After Schlager (2003), modified .
