Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.

Tephrochronology - Wikipedia

The Minoan chronology dating system is a measure of the phases of the Minoan civilization.

In Nikolaos Platon proposed a new chronology at the Prehistoric Conference in Hamburg, based on the development of the architectural complexes known as "palaces" at Knossos , Phaistos , Malia , and Kato Zakros. The academic community accepted the scheme but not as a replacement, simply stating where in Evans' system the new terms fit.

Radiometric Age Dating

Aegean civilizations , the Stone and Bronze Age civilizations that arose and flourished in the area of the Aegean Sea in the periods, respectively, about — bc and about — bc. The area consists of Crete , the Cyclades and some other islands, and the Greek mainland, including the Peloponnese , central Greece , and Thessaly. The first high civilization on European soil, with stately palaces, fine craftsmanship, and writing, developed on the island of Crete. Later, the peoples of the mainland adapted the Cretan civilization to form their own, much as the Romans adapted the civilization of later Greece. The Bronze Age civilization of Crete has been called Minoan , after the legendary King Minos of Knossos, which was the chief city of the island throughout early times.

As you have learned from our previous posts , loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating , radiocarbon dating , magnetic stratigraphy , and orbital tuning.
