This site contains lecture notes from a short course on microstructures. The topic presented is grain shape foliation, which is defined as the preferred alignment of elongate grains. Processes that affect the development of a grain shape foliation are discussed, along with crystallographic preferred orientations, the grain size vs. stress relationship, and dislocation creep regimes in quartz aggregates. The notes are well illustrated, and links to further references are provided. This resource is part of the Teaching Petrology collection.
