项目摘要
Adrian Lenardic A continental craton is a region that has remained tectonically stable for on the order of a billion years. Many cratons are also associated with thick lithosphere that has been isolated from mantle recycling for an equally long period of time. Understanding the factors that provide for the stability of cratons and for the longevity of deep cratonic lithosphere are related issues that bridge the gap between studies of continental tectonics and of mantle dynamics. To address these issues, the investigators will constrain the present day thermo-chemical structure and explore the thermo-tectonic evolution of the crust and mantle lithosphere below several cratons. They will work with collaborators from Montreal and Australia to collect and compile data constraints for thermal models of the cratonic lithosphere in the Canadian Shield and in Western Australia. They will then develop data constrained models for the present day thermo-chemical structure of cratonic lithosphere within these regions. The heat that comes from the convecting mantle will be treated in a fully self-consistent way and both vertical and lateral variations in lithospheric structure will be explored. The researchers will also work directly with data oriented colleagues to collect, analyse, and synthesize all the data that can constrain the evolution of target cratons. They will then explore models of coupled mantle convection and continental tectonics to isolate the factors that allow for the longevity of deep cratonic lithosphere and the stability of cratonic crust. This will be accomplished using a powerful new numerical simulation tool that has been designed to bridge the gap between mantle convection modeling and continental tectonics modeling. The advanced modeling methodology, together with the data that will be brought to bear on the problem at hand, will allow this team to develop rigorous and testable models that address the cratonization of continental crust and the longevity of cratonic lithosphere in a self-consistent manner.
大陆克拉通是一个在大约10亿年的时间里保持构造稳定的地区。许多克拉通还与厚岩石圈有关,这些岩石圈与地幔循环分离了同样长的时间。了解克拉通稳定性和深克拉通岩石圈寿命的因素是连接大陆构造和地幔动力学研究之间差距的相关问题。为了解决这些问题,研究人员将限制现今的热化学结构,并探索几个克拉通下面地壳和地幔岩石圈的热构造演化。他们将与来自蒙特利尔和澳大利亚的合作者一起收集和汇编加拿大地盾和西澳大利亚的克拉通岩石圈热模型的数据约束。然后,他们将开发这些地区克拉通岩石圈现今热化学结构的数据约束模型。来自对流地幔的热量将以完全自一致的方式处理,岩石圈结构的垂直和横向变化将被探索。研究人员还将直接与数据导向的同事合作,收集、分析和综合所有可以限制目标克拉通演化的数据。然后,他们将探索地幔对流和大陆构造耦合的模型,以分离出允许深克拉通岩石圈寿命和克拉通地壳稳定性的因素。这将使用一种强大的新型数值模拟工具来完成,该工具旨在弥合地幔对流建模和大陆构造建模之间的差距。先进的建模方法,以及将用于解决手头问题的数据,将使该团队能够开发出严格且可测试的模型,以自一致的方式解决大陆地壳的克拉通化和克拉通岩石圈的寿命问题。
