For each dating or chronological method there is a link in the box at right to take you to that section of this page.

There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.

Everything around us is made of chemical compounds that have testable and identifying characteristics, allowing them to be classified, and their age determined.

This also applies to rocks, minerals, and derivative materials (such as sediments and soil).

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.However, human beings love to see factual precision, and we want to know how old something is.Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.This section presents many basic concepts that are universal to all physical sciences.1. A mineral is a naturally occurring, inorganic (never living) solid with a definite internal arrangement of atoms (crystal structure) and a chemical formula that only varies over a limited range that does not alter the crystal structure.What are "rocks" and "minerals" - explain the differences. Describe essential concepts of chemistry related to earth materials. What is the chemical and mineral composition of the Earth's crust? List some common silicate and nonsilicate minerals. Describe and illustrate the "rock cycle" as it relates to processes and products. Describe basic geologic principles for interpreting landscape forming processes. On Earth, more than 4,000 minerals have been identified, however, of those fewer than 2 dozen are common minerals in Earth's physical environment (Figure 1-1 shows common rock-forming minerals).This chapter is an introduction to rocks and minerals, and the rock cycle.Basic chemistry is important to all sciences, especially geology!Far from being data, these dates are actually interpretations of the data.As discussed before, the assumptions influence the interpretation of the data.The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.
