What geologic principles are used in relative age dating

If conditions are right the remains of the dying organisms can then be preserved as fossils within the rock that formed from sediments that covered the remains. Life today has body parts ranging from hard bones and shells to the soft cellulose of plants, to soft-bodied organisms like jellyfish, down to single celled bacteria and algae. Fission track dating relies on damage to the crystal lattice produced when the unstable U decays to the daughter product Th releasing an alpha particle. The simpler the organism the older it is assumed to be. Superposition and cross-cutting are helpful when rocks are touching one another, but are useless when rocks are kilometers or even continents apart. With this principle in mind, geologists conclude that examples of folds and tilted beds represent the consequences of deformation after deposition. What is meant by dating rocks relatively rather than absolutely? Distinctive rock layers, called key beds, are also useful for correlating rock units. The application of the Principles of Stratigraphy by 18th and 19th century geologists resulted in the development of the Geologic Time Scale. Each of them is a testable hypothesis about the relationships between rock units and their characteristics. Disconformities are an erosional surface between two sets of rock layers. The The Laws of Relative Dating.

Relative dating utilizes six fundamental principles to determine the relative age of a formation or event. The first principle is the Principle of Superposition which states that in an undisturbed succession of sedimentary rock, the oldest layers are on the bottom. Geologic age dating is an entire discipline of its own. In a way, this field, called geochronology, is some of the purest detective work earth scientists do. There are two basic approaches: relative geologic age dating, and absolute geologic age dating. Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata). Relative dating does not provide actual numerical dates for the rocks.
