Crystal-scale observations of rock microstructures and textures provide a fundamental basis for understanding the petrogenesis of igneous, metamorphic and mineralised rocks. Petrography remains at the heart of petrological investigation: it provides the observations to develop new hypotheses and the context needed to interpret increasingly sophisticated textural, geochemical, and computational datasets. This session celebrates the value of detailed petrographic observations and highlights how traditional and modern datasets can be combined to reconstruct geological processes across a wide range of spatial and temporal scales.
We invite contributions applying textural and microstructural approaches to igneous, metamorphic, and mineralised systems, with particular emphasis on studies that place petrography and microstructural observations at the centre of geological interpretation. This may include contributions that combine traditional (e.g., optical microscopy, universal stage) and modern (e.g., EBSD, X-Ray-Tomography and -Ptychography, chemical mapping, XMapTools) methods, as well as submissions focused on advances in quantitative petrography, 3D and 4D imaging, and numerical models of microstructural and/or textural evolution.
