There are a number of different types of intrusions, including stocks, laccoliths, batholiths, sills and dikes.

Cross-cutting relations can be used to determine the relative ages of rock strata and other geological structures.

Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.Relative dating by biostratigraphy is the preferred method in paleontology, and is in some respects more accurate (Stanley, 167–69).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.This aspect of Werner's model was useful for explaining the origin of tilted sedimentary rocks.(dark brown) Flat lying sedimentary rocks were eventually precipitated.
