This chapter is an introduction to rocks and minerals, and the rock cycle.
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.
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).
Relative dating places events or rocks in their chronologic sequence or order of occurrence.
Absolute dating places events or rocks at a specific time.
