Compositional domains in the subcontinental lithospheric mantle reflect the processes of continental assembly and breakup through Earth's history. Their boundaries may focus the fluid movements that produce giant ore deposits. Mapping these boundaries will provide fundamental insights into Earth processes and a basis for the targeting of mineral exploration. We will integrate mantle petrology, tectonic synthesis and geophysical analysis to produce the first maps of the architecture of the continental lithosphere, to depths of ca 250 km. These maps will provide a unique perspective on global dynamics and continental evolution, and on the relationships between lithosphere domains and large-scale mineralisation.

大陆岩石圈地幔的成分域反映了地球历史上大陆的组装和裂解过程。它们的边界可能集中了产生巨大矿床的流体运动。 绘制这些边界图将提供对地球过程的基本了解，并为矿产勘探的目标奠定基础。 我们将综合地幔岩石学、构造综合和地球物理分析，绘制出第一张大陆岩石圈结构图，深度约为250公里。 这些地图将为全球动力学和大陆演化以及岩石圈域与大规模矿化之间的关系提供独特的视角。
