Published in Geostandards and Geoanalytical Research, under an open-access licence, this article by Steven M. Reddy, Leader of the Geoscience Atom Probe research group at the John de Laeter Centre, Curtin University, Australia provides an overview of APT, including the historical development and technical aspects of the instrumentation, and the fundamentals of data acquisition, data processing and data reconstruction. It also reviews previous studies and highlights the potential future applications of nanoscale geochemical studies of natural materials.

Although developed and mostly used in the materials science and semiconductor fields, recent years have seen increasing development and application of Atom Probe tomography in the geoscience and planetary science disciplines. Atom probe studies demonstrate compositional complexity at the nanoscale and provide fundamental new insights into the atom-scale mechanisms taking place in minerals over geological time.
