The project intends to enable full quantitative separation of magnetic mineral mixtures in natural materials to unlock details of important environmental processes. Most efforts to understand ancient variations of Earth’s magnetic field using palaeomagnetism, or climate change using environmental magnetism, are complicated by the presence of mixed assemblages of magnetic rock-forming minerals. Understanding the recording of palaeomagnetic information or decoding environmental processes requires separate quantification of each mineral component. The main aim of the project is to develop a method to unmix the magnetic components present in environmental and geological materials. The proposed approach is expected to unlock a new quantitative era in rock magnetism, and to have impacts in physics as well as Earth science.

该项目旨在实现天然材料中磁性矿物混合物的全面定量分离，以揭示重要环境过程的细节。大多数使用古地磁学来理解地球磁场的古代变化，或使用环境磁学来理解气候变化的努力，都因磁性成岩矿物的混合组合的存在而变得复杂。了解古地磁信息的记录或解码环境过程需要对每种矿物成分进行单独的量化。该项目的主要目的是开发一种方法，将环境和地质材料中存在的磁性成分分开。该方法有望开启岩石磁学的一个新的定量时代，并对物理学和地球科学产生影响。
