Nonradiogenio dating methods

Other dating techniques are available that do not use the radiometric properties of materials. These techniques are often used on objects dating from the past 100,000 years of the Earth's history and involve correlating physical phenomena with natural cycles. The most well-known technique is dendrochronology, also known as tree-ring dating. Other cyclical techniques include analyzing ice cores and varves (annual sediment layers from lakes). These methods will be discussed in greater detail in chapters 5 and 6. Three nonradiogenic dating techniques cli-matologists rely on are (1) orbital tuning techniques, (2) thermoluminescence, and (3) electron spin resonance.
