### Can all radiometric dating methods be wrong?

In regard to the radiometric dating of rocks, it is known that various different radiometric methods often yield quite discordant dates for the same rock, thus proving that they cannot all be correct.

### What is the difference between relative rock dating and absolute dating?

Your question is quite convoluted, but I will try my best. Relative rock dating is used on sedimentary rocks.. Where as absolute age dating (U-Pb, Ar/Ar etc.) are used on minerals from igneous and metamorphic rocks, as they can date the age of crystallization or metamorphism the rock experienced.

### How do geologists date rocks and fossils?

Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil? This page has been archived and is no longer updated Dating Rocks and Fossils Using Geologic Methods

### Is radiometric dating based on index fossils?

Claim: Radiometric dating is based on index fossils whose dates were assigned long before radioactivity was discovered. Response: This is not at all true, though it is implied by some young-earth literature. Radiometric dating is based on the half-lives of the radioactive isotopes. These half-lives have been measured over the last 40-90 years.

### How reliable is radiometric dating?

The reliability of radiometric dating is subject to three unprovable assumptions that every geologist must make when using the radioactive “clock”. Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate.

### Why do scientists reject all but the oldest dating methods?

Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of the earth’s age many years ago.

### What is the most common radiometric dating method for uranium?

One common radiometric dating method is the Uranium-Lead method. This involves uranium isotopes with an atomic mass of 238. This is the most common form of uranium.

### Could radiocarbon dating be misleading you?

That may not seem like a huge deal, but in situations where a decade or two of discrepancy counts, radiocarbon dating could be misrepresenting important details. The science behind the dating method is fairly straightforward: nitrogen atoms in the atmosphere hit with cosmic radiation are converted into a type of carbon with eight neutrons.

### How is radiometric dating used to date fossils?

Radiometric dating is based on the half-lives of the radioactive isotopes. These half-lives have been measured over the last 40-90 years. They are not calibrated by fossils.

### How do geologists date rocks and fossils?

### What is the primary dating tool for geologic time?

“Few people realize that the index fossil dating system, despite its poor assumptions and many problems, is actually the primary dating tool for geologic time. … In other words, radiometric dating methods are actually fit into the geological column, which was set up by fossil dating over 100 years ago.

### How many radiometric dating methods are there?

There are well over forty different radiometric dating methods, and scores of other methods such as tree rings and ice cores. All of the different dating methods agree--they agree a great majority of the time over millions of years of time. Some [skeptics] make it sound like there is a lot of disagreement,...
