Modeling the Dispersion of Plume Heads Beneath Ridges and the Growth of Large Igneous Provinces

这项研究将使用数值和实验室（模拟）模型相结合，以调查的分散和相互作用的羽头和覆盖的岩石圈板块，他们的冲击。模型将包括熔化的影响，在和离轴的情况下，和脊分割和板块流变沿轴流动的影响。 模型包括2D和3D数值模型以及3D比例模拟模型。建模将包括两个羽头（LIP），和他们的更稳定的状态尾巴。在一般情况下，实验将探讨热，成分和动态演变的羽头的一系列条件。更具体的模型将检查的情况下，翁东爪哇高原系统-地球上最大的已知羽头。建模工作是观察、理论、预测和更多观察周期的一部分，预计将导致具体的ODP钻井建议。

This study will use a combination of numerical and laboratory (analog) models to investigate the dispersal and interaction between plume heads and the overlying lithospheric plates upon which they impinge. Models will include the effects of melting, on and off-axis cases, and the influence of ridge segmentation and plate rheology on along-axis flow. Models include both 2D and 3D numerical models and 3D scaled analog ones. The modeling will include both plume heads (LIPs), and their more steady-state tails. In general, the experiments will explore the thermal, compositional, and dynamic evolution of plume heads for a range of conditions. More specific models will examine the case of the Ontong-Java plateau system- the earth's largest known plume head. The modeling efforts are part of a cycle of observations, theory, predictions, more observation which is expected to lead to specific ODP drilling proposals.
