Dating is not necessary to demonstrate that evolution is a fact.Chronological sequence is all that is really required.The most compelling argument for an age of the earth of 4.5 billion years are the large number of independent tests that have been used to confirm this date.

You may find it useful for the clear definitions, and for excellent links on a variety of topic.

It excludes contamination and weathering of travertines and makes possible more precise dating of thin deposits of secondary carbonates.

No web-based resource for this method is available.

These tests have consistently given the same ages for each of these objects.

Examples of a number of consistent dates derived from different methods are given.

A short but clear explanation about radioactive isotopes commonly used for determining ages of rocks (with graphics) and putting numbers on the geologic time scale, extending it back before the occurance of abundant index fossils.

This is a relatively new method intended to to improve the precision of uranium and thorium istopy methods.

Further, he proposed that wherever uncontorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.

The Major Divisions of Geologic Time are shown here, arranged in chronological order with the oldest division at the bottom, the youngest at the top. Specifically, stratigraphy refers to the application of the Law of Superposition to soil and geological strata containing archaeological materials in order to determine the relative ages of layers.

Cross-dating is a technique used to take advantage of consistencies in stratigraphy between parts of a site or different sites, and objects or strata with a known relative chronology.
