Our research in rock magnetism deals with magnetic mineral grains which act as "fossil compasses". The aim is to obtain records of ancient magnetic fields, for the Earth and other bodies, such as Mars and meteorites. Both magnetic field intensities and directions are of interest. The purpose is to understand the core dynamos of the Earth and other planets and plate tectonic motions of continents and seafloor, as well as the microscopic mechanisms by which minerals retain a magnetic memory stable over geological time. Specific projects include:

我们在岩石磁性方面的研究涉及充当“化石罗盘”的磁性矿物颗粒。 目的是获得地球和其他天体（例如火星和陨石）的古代磁场记录。 磁场强度和方向都很重要。 目的是了解地球和其他行星的核心发电机以及大陆和海底的板块构造运动，以及矿物在地质时期保持磁记忆稳定的微观机制。 具体项目包括：
