Today we restrict this principle to sedimentary rocks, which were understood differently in Steno's time. The formation of melt inclusions appears to be a normal part of the crystallization of minerals within magmas, and they can be found in both volcanic and plutonic rocks. The principle of Uniformitarianism states that the geologic processes observed in operation that modify the Earth's crust at present have worked in much the same way over geologic time.

Due to that discovery, Smith was able to recognize the order that the rocks were formed. Dinosaurs and the History of Life. Two of the most common uses of melt inclusions are to study the compositions of magmas present early in the history of specific magma systems.

If sufficient sedimentary material is available, it will be deposited up to the limits of the sedimentary basin. Numerical dates define the actual age of a particular geologic event. Therefore newer sediment is continually deposited on top of previously deposited or older sediment. As a result, xenoliths are older than the rock which contains them.
