Due to the mobility and incompatibility of lithium (Li) in the crust and on Earth’s surface, the Li mineral system is complex and highly interlinked. In most cases, the development of economic Li brine systems depends upon the concentration, transport, deposition and remobilization of Li from magmatic systems. As such, a complete understanding of where and why Li becomes concentrated in the crust and at Earth’s surface, from source to sink, is highly desirable and requires integrated knowledge of the Li mineral system. Development of integrated data and exploration tools for global and regional resource assessment is key for accelerated understanding and targeting of Li resources. CGG are developing a suite of exploration tools to inform global resource assessments and target generation for a wide range of Li brine deposit styles. These tools are underpinned by our integrated approach to the Li mineral system, which informs our understanding of the sources, transport, deposition, enrichment and preservation factors affecting this system.
