Principles of dating sedimentary rocks

On this page, we will discuss the Principles of Geology. The Law of Superposition states that beds of rock on than Unit J (burnt orange) because it lies atop it, this also directly relates to the relative age dating. that a long amount of time has been eroded away before the younger sedimentary rocks were deposited.

Principles of Relative The Principle of Superposition tells us that deeper layers of rock are older than shallower layers Relative dating utilizes six fundamental principles to determine the relative age of a formation or event. This follows due to the fact that sedimentary rock is produced from the gradual accumulation of sediment on the surface. For purposes of relative dating this principle is used to identify faults and erosional features within the rock record.

Since, all sedimentary rock is formed through the principle of dating sedimentary rocks accumulation of sediment at the surface over time, and since the principle of superposition tells us that newer sediment is deposited on top of older sediment, the same must also be true for fossils contained within the sediment.
