Some limitations carbon dating
This page does not attempt to cover the details of wood formation that make tree rings possible, but rather provides an overview of common wood characteristics and anomalies that you will need to identify when you are crossdating.
Variation in these rings is due to variation in environmental conditions when they were formed.
This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
It implies that relative dating cannot say conclusively about the true age of an artifact.
For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.
