The development of Atomic Absorption Mass Spectrometry in recent years, a technique that allows one to count the individual atoms of 14C remaining in a sample instead of measuring the radioactive decay of the 14C, has considerably broadened the applicability of radiocarbon dating because it is now possible to date much smaller samples, as small as a grain of rice, for example.
Dendrochronology is another archaeological dating technique in which tree rings are used to date pieces of wood to the exact year in which they were cut down.
Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.
If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery.
The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.
The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.
Chronometric methods include radiocarbon, potassium-argon, fission-track, and thermoluminescence.This parallelism is formed due to trade relations, particularly wehen trade followed in both directions.For example, beads closely resembling those from the temple repositories at Cnoss and dating from C.1600 B.But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.Even when the absolute dates are available, we have to supplement the information with relative dating.
