Chemical techniques of relative dating

The science of geology is founded on basic principles that are useful for making observations about the world around us.

This chapter presents a mix of information that is essential (fundamental) to all following chapters.

Libby cleverly realized that carbon-14 in the atmosphere would find its way into living matter, which would thus be tagged with the radioactive isotope.

Based at the University of Wales Trinity St David, he has devoted his career to studying the Quaternary period – the last 2.6 million years and the so-called ‘age of humans’.He was inspired by physicist Serge Korff (1906–1989) of New York University, who in 1939 discovered that neutrons were produced during the bombardment of the atmosphere by cosmic rays.Korff predicted that the reaction between these neutrons and nitrogen-14, which predominates in the atmosphere, would produce carbon-14, also called radiocarbon.This chapter is an introduction to rocks and minerals, and the rock cycle.Basic chemistry is important to all sciences, especially geology!
