报告摘要
Environmental geophysics aims to reveal subsurface processes that cannot be directly observed, by interpreting indirect physical signals. We focus on understanding processes such as groundwater storage and distribution, pore fluid dynamics, and rock weathering, all governed by interactions between subsurface structure, fluids, and minerals across multiple scales. The central challenge is that we routinely face heterogeneous media, incomplete observations, weak or non-unique signals, and processes evolving across a wide range of spatial and temporal scales.In this talk, I will show how geophysical signals, in particular low-field nuclear magnetic resonance (NMR) and electrical methods, can be used to characterize fluids and fluid–solid interactions in soils and rocks. Special attention will be given to how NMR relaxation and multimodal measurements yield information on fluid state, pore structure, solute transport, and evolving solid–liquid interfaces. Drawing on examples from unsaturated flow, freeze–thaw cycling, and water–rock interaction, I will address a question that extends well beyond geophysics: how can indirect physical measurements be translated into mechanistic understanding of complex and dynamic geomaterials?
