This method can help answer key questions in the geomechanics field about compaction processes in rocks. The main advantage of this technique is that it allows quantitative measurement of the local elastic field within rock and mineral aggregates.

We report detailed procedures for compression experiments on rocks and mineral aggregates within a multi-anvil deformation apparatus coupled with synchrotron X-radiation. Such experiments allow quantification of the stress distribution within samples, that ultimately sheds light on compaction processes in geomaterials.
