The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.

The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.

Due to that discovery, Smith was able to recognize the order that the rocks were formed.

Sixteen years after his discovery, he published a geological map of England showing the rocks of different geologic time eras.

Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age, (i.e. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.

These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park.

Many isotopes have been studied, probing a wide range of time scales.Methods for relative dating were developed when geology first emerged as a natural science in the 18th century.Geologists still use the following principles today as a means to provide information about geologic history and the timing of geologic events.The principle of cross-cutting relationships pertains to the formation of faults and the age of the sequences through which they cut.Faults are younger than the rocks they cut; accordingly, if a fault is found that penetrates some formations but not those on top of it, then the formations that were cut are older than the fault, and the ones that are not cut must be younger than the fault.
