Whatever caused this igneous intrusion occurred after the strata formed. However, the layer of that material will become thinner as the amount of material lessens away from the source.Sediment will continue to be transported to an area and it will eventually be deposited.Using microscopic observations and a range of chemical microanalysis techniques geochemists and igneous petrologists can obtain a range of useful information from melt inclusions. Essentially, this law states that clasts in a rock are older than the rock itself.

All the data collected are organized, analyzed, interpreted or synthesized to give the required results.Craters are very useful in relative dating; as a general rule, the younger a planetary surface is, the fewer craters it has.Now, what if instead of being horizontal, this rock layer was found in a tilted position?The stratigraphic column for the Earth was built up over a few hundred years, mainly since the 18 century, the opinions or the explanations of time distribution of organisms were greatly influenced by Cuvier, a French vertebrate paleontologist, and his followers.According to Cuvier, each major period of geologic time was terminated by a world-wide catastrophe which wiped out all life.

This process lead to a system of time containing eons, eras, periods, and epochs all determined by their position in the rock record.
