Ultrafast LIBS elemental imaging: a new tool for pedogenesis studies in highly polluted anthropogenic soils

Abstract

In this communication, we report the first LIBS imaging of soil thin sections at 25 μm resolution over 25 cm² with a 100 Hz acquisition rate. Coupled with micromorphology, this approach enables high-throughput elemental mapping, enhancing the analysis of soil structure, composition, and anthropogenic influences through nearly 4 million laser shots.
