are used to date volcanic rock and ash deposits. The chronometric, or time measurement, utility of dendrochronology has the longest historical past and is essentially the most generally recognized to nonspecialists. Tree-ring dating is routinely used so far artifacts, options, sites, and, by extension, abstract archaeological entities including durations, stages, phases, and styles. Tree-ring dates have additionally been used to confirm and supply absolute dates for chronological sequences offered by relative dating techniques together with seriation and stratigraphic analysis.

Another methodology of courting utilized by archaeologists depends on typological sequences. This technique compares created objects to other objects of comparable look with the goal of figuring out how they're associated. This technique is employed by many subdisciplines of archaeology to know the relationships between frequent objects. For instance, typological sequencing is commonly performed on spearpoints created by Indigenous peoples by comparing the types of points discovered at totally different locations and analyzing how they modified over time based mostly on their relative positions in an archaeological web site.
