Chronology: Tools and Methods for Dating Historical and Ancient Deposits, Inclusions, and Remains
Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people.
The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past. All dating methods today can be grouped into one of two categories: absolute dating , and relative dating. The former gives a numeric age for example, this artefact is years old ; the latter provides a date based on relationships to other elements for example, this geological layer formed before this other one.

Define relative dating and radiometric dating
Chronometric dating has revolutionized archaeology by allowing highly accurate dating of historic artifacts and materials with a range of scientific techniques. Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.
Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history. Scientists first developed absolute dating techniques at the end of the 19th century. Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions.
Basic textbooks on archaeological method and theory relate that there are two methods of establishing chronology: 1) methods of relative dating (ascertaining the.

What is the major difference between relative dating and absolute dating methods
Today, most of the methods utilized for chronometric dating of fossils are radiometric. Radiometric dating, in general, refers to the dating of material by using the known rate at which certain radioactive isotopes decay, or at what rate there are collective changes due to radioactivity. Even though isotopes of an element can be different when it comes to atomic mass, the atomic number of the isotope is always the same. Radioactive elements decay at unique rates, dependant on the isotope.
By measuring this decay, and knowing the half life of an element, scientists can date a sample.

Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year.
Fluorine dating in terms chronometric.
Absolute, or chronometric, dating techniques provide us with measurable dates-day, year, millennia, for example. Relative techniques provide a basic order to.
Having an accurate time scale is a crucial aspect of reconstructing how anatomical and behavioral characteristics of early hominids evolved. 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.
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. 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.
