Chat without signing - Archaeology chronometric dating

Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.

In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history).

From 500 AD, the civilization started to decline and by 750 AD the civilization had fallen completely.

This is thought to have occurred when an El Niño triggered widespread and destructive flooding.

The Nazca Province in the Ica Region was named for this people.

Nazca society developed during the Early Intermediate Period and is generally divided into the Proto Nazca (phase 1, 100 BC – 1 AD), the Early Nazca (phases 2–4, 1–450 AD), Middle Nazca (phase 5, 450–550 AD) and Late Nazca (phases 6–7, 550–750 AD) cultures.

The most common relative dating method is stratigraphy.

Other methods include fluorine dating, nitrogen dating, association with bones of extinct fauna, association with certain pollen profiles, association with geological features such as beaches, terraces and river meanders, and the establishment of cultural seriations.

Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.

It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.
