Great Barrier Reef: Origin, Evolution, and Modern Development, Figure 16 (a) Low stand position shows the pedestal on which
One Tree Reef sits. (b) high stand growth of One Tree Reef on its pedestal and (c) Stanley reef - a mid shelf reef in the central reef
region. The lithologies encountered in drill holes indicate a framework-dominated windward margin and a sand dominated lee
margin. Plots of depth against age show the windward margin getting to sea level first and progressively later backwards.
