Petrological and geochemical studies of erupted products provide insights into processes and timescales involved in the construction and eruption of magmatic systems. However, petrogenesis in magmatic systems is highly non-linear resulting in magma reservoirs that are heterogeneous at different spatial and temporal scales. Volcanic eruptions only sample discrete parts of the magmatic system at a given time and it is therefore essential to understand how large-scale magmatic processes are represented in the rock and mineral record. 

Statistically representative datasets are required to fully describe the complexity of a magmatic system in space and time. The study of the plutonic rock record may also bring insights on the non-erupted parts of a magmatic system. Thus we encourage the submission of studies that attempt to explore and quantitatively translate the complexity of magmatic processes and the heterogeneity of magmatic systems into geochemical and petrological observations.
