Range of potassium argon dating
The quantitative approach is admirable, but Buffon's assumptions are flawed. Silicate minerals have lower heat conductivity than steels and are better insulators leading to slower cooling rates.Second, the calculations did not incorporate the heating effects of radioactive decay.This means trilobites, dinosaurs, and mammals all dwelled on the planet simultaneously, and they perished together in this world-destroying cataclysm.Although creationists have long pointed out the rock formations themselves testify unmistakably to water catastrophism on a global scale, evolutionists generally have ignored this testimony.That is, the earth accreted from small, cold chunks of material and then heated up at a later time.Isotope: A version of an atom that differs from other atoms of the same element only in the number of neutrons.
Isotopic age dating would not give the age of the sediment deposition or lithification, but rather the age of the source rocks.
Strata Thickness- In the late 1800s, a British geologist estimated that 75 million years has lapsed since the beginning of the Cambrian.
This estimate was based upon the maximum known thickness of strata (from Cambrian to present) divided by the average rate of sedimentation in modern environments. Joly used the salinity of ocean water to determine the age of the earth.
He calculated the modern rate of salt delivery to the oceans, and suggested that the present salinity of ocean water would take at least 100 million years to develop.
In the 1860's, English physicist Lord Kelvin disagreed with Charles Lyells proposition that the earth behaves in a uniform, unchanging manner.

Chronological Analysis of the Scriptures- Literal interpretation of the scriptures led some people to conclude that the Earth was created approximately 6,000 years old.
