E124: early methods of determining geologic time, such as the use of index fossils and stratigraphic sequences, allowed for the relative dating of geological events however, absolute dating was impossible until the discovery that certain radioactive isotopes in rocks have known decay rates, making it possible to determine how many years ago a .
Purpose: to use relative dating techniques to interpret geological cross sections procedure: today we will be interpreting geologic history from geologic cross-sections geologic history is a series of events that resulted in the. 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. Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc this technique does not give specific ages to items it only sequences the age of things or determines if something is older or younger than other things.
A relative age is the age of a fossil organism, rock, or geologic feature or event defined relative to other organisms, rocks, or features or events rather than in terms of years tradition paleontological and biostratigraphic correlation methods are still perhaps the most common relative dating methods used by geologists.
