Seismic tomography using signal and noise: A new window into deep Earth

该项目将结合基于地震记录的传统成像技术和最先进的环境噪声层析成像技术，利用海洋和大气扰动，构建澳大利亚东南部地壳和上地幔的详细模型。这项研究在全国范围内的好处包括：极大地提高了对澳大利亚板块深部结构及其随时间演变的了解；地震数据解释的范式转变，这将提高澳大利亚在国际科学界的声誉；以及对拥有世界级矿藏的远景区域的广泛地质方面的重要新限制。

This project will combine traditional imaging techniques based on earthquake records, and state of the art ambient noise tomography, which exploits oceanic and atmospheric disturbances, to construct detailed models of the crust and upper mantle beneath southeast Australia. The national benefits of this research include: a vastly improved understanding of the deep architecture of the Australian Plate, and how it has evolved over time; a paradigm shift in the interpretation of seismic data, which will enhance Australia's reputation in the international scientific community; and important new constraints on the broad scale geology of prospective regions that host world class mineral deposits.
