Stratigraphy helps date rocks from "summary" of Principles of Geology, Volume 1 by Charles Lyell,Sir Charles Lyell
Stratigraphy, the study of rock layers and the sequence in which they were deposited, plays a crucial role in determining the relative ages of rocks. By examining the different layers of sedimentary rock, geologists can infer the relative order in which they were formed. This is based on the principle of superposition, which states that in undisturbed rock layers, the oldest layers are found at the bottom while the youngest are at the top. Furthermore, the concept of stratigraphy allows geologists to correlate rock layers from different locations by matching up similar sequences of layers. This can help establish a timeline of geological events and determine the relative ages of rocks in different areas. By looking at the fossil assemblages found within these rock layers, geologists can also gain insight into the relative ages of the rocks. Fossils are useful for dating rocks because they provide a record of past life forms and can be used to establish the relative ages of rock layers. Certain fossils are characteristic of specific time periods, allowing geologists to use them as markers to date the rocks in which they are found. By comparing the fossil assemblages in different rock layers, geologists can determine the relative ages of these rocks and create a timeline of geological events.- The concept of stratigraphy is essential for dating rocks and understanding the geological history of a region. By examining the sequence of rock layers, correlating them between different locations, and studying the fossil assemblages within them, geologists can establish a relative timeline of geological events and gain insight into the Earth's past. This process of using stratigraphy to date rocks is fundamental to the field of geology and has been instrumental in shaping our understanding of the Earth's history.
