How do scientists use carbon dating to estimate the age of fossils

Navigation by records

By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site. But even if it is true that older radiometric dates are found lower down in the geologic column which is open to questionthis can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later.

But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes. Henry Morris as follows:.

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. A paleontologist would take the discovered fossil to a geologist who would ask the paleontologist what other fossils searching for an index fossil were found near their discovery.

All radiometric dating methods use this basic principle to extrapolate the age of artifacts being tested. Other confounding factors such as contamination and fractionation issues are frankly acknowledged by the geologic community, but are not taken into consideration when the accuracy and validity of these dating methods are examined.

The following is an article on this subject. Sedimentary rock typically is layered, with the layers derived from different periods of sediment accumulation. Beware of people who subscribe to a theory based upon naturalism and materialism exclusively. Until the middle of the last century, "older" or "younger" was the best scientists could do when assigning ages to fossils.

For example, if a magma chamber does not have homogeneously mixed isotopes, lighter daughter products could accumulate in the upper portion of the chamber. The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy. Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades.

This is the major flaw in radiometric dating, e. After 5, years, the amount of carbon 14 left in the body is half of the original amount. The mathematical premise undergirding the use of these elements in radiometric dating contains the similar confounding factors that we find in carbon dating method.

However, the principle of carbon dating applies to other isotopes as well. How did dinosaurs leave tracks in solid stone? Navigation by records 1 2 Further.

The fact remains that every living organism appears abruptly in the fossil record, fully formed without the transitional fossils that should be there if Darwinian evolution is true.
