Sedimentary structures
https://australian.museum/learn/minerals/shaping-earth/sedimentary-structures/Sedimentary structures can be of either physical (e.g. wave action) or biological (e.g. disruption of sediments by animals) origin.

Crystallography
https://australian.museum/learn/minerals/what-are-minerals/crystallography/Minerals can be identified by the shape of their crystals: called crystallography. External crystallography measures the outside properties of crystals such as length of crystal surfaces and the angles between these surfaces.
