This theory held that the past was the key to the future and that processes that formed the layers were the very slow processes that we see forming layers at the bottom of the ocean today. Until Lyell successfully convinced scientists that uniformitarianism was the correct theory, it was believed that the worldwide flood and other catastrophic events were primarily responsible for the formation of the geologic layers and that they didn’t represent long ages.

Ice cores showed the age of a military plane buried in the artic as thousands of years old.

Similarly, dendrochronology measures the tree rings in trees and assumes they represent years.

Consequently, today the dates assigned to the “standard geologic column” are still based upon Lyell’s assignment where index fossils are used to date the rocks and the rocks are used to date the fossils. Today, it is not surprising that many geologists are rejecting uniformitarianism and embracing catastrophism again.

There is much evidence that refutes uniformitarianism. Helens demonstrated that rapid deposition and rapid canyon erosion are a fact. Also, when life forms die they only become fossils when they are buried rapidly. Polystrate tree fossils that extend through multiple layers are common. Consequently, the uniformitarianism model, along with the age assignments of the geologic column, is in doubt. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.

Climate chronology uses evidence of a climatic change, such as an ice age, as a benchmark for dating.

states, “Before the 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques.

With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old?

Although there might be some mineral differences due to the difference in source rock, most sedimentary rock deposited year after year look very similar to one another.

Ice core sampling normally uses the assumption that the ring bands observed represents years.
