Do geologists use radiometric dating
By measuring the amount of the parent and daughter isotopes in a crystal, and then applying the decay rate, the actual age in years since the rock crystallized can be calculated.Check out this video on the Uranium – Lead dating method: Biostratigraphy is a relative dating method that correlates rock ages using the fossils contained within rock units.Unfortunately, much of the literature available to Christians has been either inaccurate or difficult to understand, so that confusion over dating techniques continues.The next few pages cover a broad overview of radiometric dating techniques, show a few examples, and discuss the degree to which the various dating systems agree with each other.Sedimentary and igneous rocks are often imprinted with the magnetic alignment of the Earth at the time they were formed.The record of these magnetic reversals has itself been studied to create the paleomagnetic time scale, which looks like an irregular bar code.
However, some Christians suggest that the geologic dating techniques are unreliable, that they are wrongly interpreted, or that they are confusing at best.Arguments over the age of the Earth have sometimes been divisive for people who regard the Bible as God's word.Even though the Earth's age is never mentioned in the Bible, it is an issue because those who take a strictly literal view of the early chapters of Genesis can calculate an approximate date for the creation by adding up the life-spans of the people mentioned in the genealogies.Once the age range of a number of fossil species has been established using the radiometric method, fossils can provide very useful dating information.
Fossils can also tell us much about the ancient environments in which sedimentary rocks were deposited.
Assuming a strictly literal interpretation of the week of creation, even if some of the generations were left out of the genealogies, the Earth would be less than ten thousand years old.
