To say it in a few words, you may use relative dating for analytical work, But you will need absolute dating for the final synthesis.The Permian through Jurassic stratigraphy of the Colorado Plateau area of southeastern Utah is a great example of Original Horizontality and the Law of Superposition, two important ideas used in relative dating.Methods for relative dating were developed when geology first emerged as a natural science in the 18th century.Geologists still use the following principles today as a means to provide information about geologic history and the timing of geologic events.For example, if an area used for trash has modern refuse in it such as CDs and computers, and the layer underneath has cans made of tin, then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse.However, this does not say anything about the absolute age of the layers.

However, if you are mapping an area, if you want to fit your local intuition into the regional picture, you could not do without absolute dating.Continue Reading Relative age comes up often in various fields, such as archeology.If archaeologists find a site with layers in it, they can make assumptions about the relative age based on the composition of materials in each layer.These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park.

From top to bottom: Rounded tan domes of the Navajo Sandstone, layered red Kayenta Formation, cliff-forming, vertically jointed, red Wingate Sandstone, slope-forming, purplish Chinle Formation, layered, lighter-red Moenkopi Formation, and white, layered Cutler Formation sandstone.Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate.
