Relative dating the rocks


Principles of relative dating[ edit ] Methods for relative dating were developed when geology first emerged as a natural science in the 18th century. Often, coarser-grained material can no longer be transported to an area because the transporting medium has insufficient energy to carry it to that location. Uniformitarianism[ edit ] 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. Many of the same principles are applied. The study of melt inclusions has been driven more recently by the development of sophisticated chemical analysis techniques. Scientists from the former Soviet Union lead the study of melt inclusions in the decades after World War II Sobolev and Kostyuk, , and developed methods for heating melt inclusions under a microscope, so changes could be directly observed. Law of Superposition i. Original horizontality[ edit ] The principle of original horizontality states that the deposition of sediments occurs as essentially horizontal beds. As a result, xenoliths are older than the rock which contains them A similar situation with igneous rocks occurs when xenoliths are found. By combining knowledge gained using both relative and absolute dating processes geologists have been able to produce the geologic time scale.
