“…Our models show that since the Miocene, the northeastern margin has been progressively tilted down toward the northeast (Fig. 1D), consistent with a paleoshoreline (DiCaprio et al, 2009a). See the GSA Data Repository 1 (Movies DR1 and DR2) for movies of evolving dynamic topography and temperature.…”

Drowned carbonate reefs on passive margins are puzzling because of their enormous growth potential compared to typical rates of passive margin subsidence and moderate sea-level fl uctuations. A possible solution to this paradox is that slow processes acting over geologic time weaken reefs and contribute to their ultimate demise. The Australian northeastern marginal plateaus, known for their drowned reefs, underwent a period of accelerated tectonic subsidence during the late Miocene to Pliocene that, combined with a sequence of second-order global sea-level rises, outpaced reef growth and drowned the once-thriving Miocene carbonate platforms. However, the mechanism for the observed anomalous subsidence of this relatively mature passive margin 1000 km from the nearest plate boundary is uncertain. We use a coupled plate, kinematic mantle fl ow model to show that in the late Miocene northeastern Australia overrode subducted slabs from Eocene Melanesian subduction north of Papua New Guinea. We fi nd that the rate of surface subsidence induced by the sinking slabs increases the likelihood that relative sea-level rises outpaced late Miocene reef growth. In addition to the well-known effects of long-term plate processes and short-term global sea-level and climate change, our results demonstrate that deep Earth processes can play a substantial role in driving the evolution of passive margins and coral reefs.

“…Such flooding occurred across large expanses of the continental region east of the cratonic portion of Australia marked by the Tasman Line. The northeastward motion of Australia over a descending Pacific-derived slab induced a strong negative dynamic topography signal that accentuated flooding from the mid-Cretaceous sea level highstand (DiCaprio et al, 2009;Gurnis et al, 1998;Heine et al, 2010;Matthews et al, 2011). Well-constrained models of paleogeography are an important validating mechanism for numerical models of dynamic topography, as demonstrated by Gurnis et al (1998) in the study of the Cretaceous inundation of Australia (Fig.…”

Towards community-driven paleogeographic reconstructions: integrating open-access paleogeographic and paleobiology data with plate tectonics

A variety of paleogeographic reconstructions have been published, with applications ranging from paleoclimate, ocean circulation and faunal radiation models to resource exploration; yet their uncertainties remain difficult to assess as they are generally presented as low-resolution static maps. We present a methodology for ground-truthing the digital Palaeogeographic Atlas of Australia by linking the GPlates plate reconstruction tool to the global Paleobiology Database and a Phanerozoic plate motion model. We develop a spatio-temporal data mining workflow to validate the Phanerozoic Palaeogeographic Atlas of Australia with paleoenvironments derived from fossil data. While there is general agreement between fossil data and the paleogeographic model, the methodology highlights key inconsistencies. The Early Devonian paleogeographic model of southeastern Australia insufficiently describes the Emsian inundation that may be refined using biofacies distributions. Additionally, the paleogeographic model and fossil data can be used to strengthen numerical models, such as the dynamic topography and the associated inundation of eastern Australia during the Cretaceous. Although paleobiology data provide constraints only for paleoenvironments with high preservation potential of organisms, our approach enables the use of additional proxy data to generate improved paleogeographic reconstructions

“…Conversely, deep geodynamic processes (e.g. DiCaprio et al, 2009;Duretz et al, 2011;Moucha et al, 2008) give rise to the topography, erosion, and sediment generation that are the basis of surface geology. It is the surface manifestations of these deep geodynamic processes that have societal impact by creating natural hazards, such as earthquakes (e.g.…”
