Some researchers suggest that the composition of granites can be used to map their source regions 15-35 km below the Earth's surface; others disagree. Our research is designed to resolve the matter, providing a firmer basis for using granite compositions to infer crustal structure and assist in mineral exploration. The research will require the development of new analytical techniques which will greatly enhance the capacity of SHRIMP, a uniquely Australian frontier technology, in a variety of new fields, e.g. biology, environmental studies and ore genesis, each of which ultimately contributes to the social and economic well-being of the Australian community.

一些研究人员认为，花岗岩的成分可以用来绘制地球表面以下15-35公里的源区;其他人不同意。我们的研究旨在解决这个问题，为利用花岗岩成分推断地壳结构和协助矿产勘探提供更坚实的基础。这项研究将需要开发新的分析技术，这将大大提高SHRIMP这一澳大利亚独特的前沿技术在生物学、环境研究和矿石成因等各种新领域的能力，而每一个领域最终都有助于澳大利亚社区的社会和经济福祉。
