We will be modelling of the dynamics of the Earth's crust and shallow lithosphere in response to the huge stresses created by plate motions. For Australia these stresses are transmitted from the distant plate boundaries, but they have a direct controlling influence on the evolution of the petroleum rich basins of Australia. These basins have reached maturity; further exploration will be in deep water where geophysical prospecting methods are unreliable. Model-driven "exploration geodynamics" methods such as those we are developing will be needed to support traditional exploration techniques in these areas.

我们将对地壳和浅层岩石圈的动力学进行建模，以响应板块运动产生的巨大应力。对于澳大利亚来说，这些应力是从遥远的板块边界传递来的，但它们对澳大利亚石油丰富盆地的演化具有直接的控制影响。这些盆地已经成熟；进一步的勘探将在地球物理勘探方法不可靠的深海进行。我们正在开发的模型驱动的“勘探地球动力学”方法将需要支持这些领域的传统勘探技术。
