The Law of Superposition, which states that older layers will be deeper in a site than more recent layers, was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century.

The regular order of occurrence of fossils in rock layers was discovered around 1800 by William Smith.

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.

Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

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

Methods for relative dating were developed when geology first emerged as a natural science in the 18th century.

Explanations: A – folded rock strata cut by a thrust fault; B – large intrusion (cutting through A); C – erosional angular unconformity (cutting off A & B) on which rock strata were deposited; D – volcanic dyke (cutting through A, B & C); E – even younger rock strata (overlying C & D); F – normal fault (cutting through A, B, C & E).

The principle of cross-cutting relationships pertains to the formation of faults and the age of the sequences through which they cut.

As a result, xenoliths are older than the rock which contains them.

The principle of original horizontality states that the deposition of sediments occurs as essentially horizontal beds.

A similar situation with igneous rocks occurs when xenoliths are found.
