WebStratigraphy. The oldest and the simplest relative dating method is stratigraphy , or stratigraphic dating . It is based on the principle of superposition , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. This principle is logical and straightforward. WebDec 14, 2016 · Answer: Stratigraphy and Biostratigraphy . Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
