Absolute geologic age refers to how long ago a geologic event occurred or a rock formed, in numeric terms, such as 65.5 million years ago.Some rocks and minerals can have their absolute age directly measured by analyzing the ratios of certain radioactive and non-radioactive isotopes they contain.Estimates of the absolute age of prehistoric and geological events and remains amounted to little more than inspired guesswork, as there was no scientific basis for testing such proposals.” With this background, it is strange that the “standard geologic column” that identifies the rock strata on the earth and assigns very old ages to those strata was developed by Sir Charles Lyell in 1830.This was done 100 years before absolute dating methods were available.Relative geologic age is established, based on such evidence as the order in which layers of sediment are stacked, with the younger layer originally on top.
He published the results of his work and established a basic set of principles for interpreting sedimentary strata.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.Seriation uses the assumption that once a tool was developed, its use would become more widespread.Stratigraphy uses the assumption that higher layers or strata were laid down after lower layers.
