Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. Two of the most common uses of melt inclusions are to study the compositions of magmas present early in the history of specific magma systems.
Relative dating determines the period of time from which an object come from based on technology, soil, anthropology, etc. The principles of typology can be compared to the biostratigraphic approach in geology.
