Radioactive dating of rock samples yahoo
Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.
Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.
Carbon-14 dating is another common technique, but it can only be used on carbon-containing things that were once alive.
The method of calculating radiometric dates is like using an hourglass.
Creationists do not necessarily disagree with this concept, but it can only be applied to layers that are found in one location and/or can be determined to have been deposited in a continuous layer over a very wide area.
There is also a difference in the timescale used to explain the layers.
Mikhail Marov of the Vernadsky Institute of Geochemistry and Analytical Chemistry said scientists had determined the meteorite's age by observing the amount of radioactive isotopes and their decay byproducts, a technique called of a granodiorite at the Cuttaburra A prospect indicates that this mineralised system may be Middle Silurian in age and thus indicating that the host rocks are older than those hosting the Cobar-type deposits.
For inorganic matter and for older materials, isotopes of other elements, such as potassium, uranium, and strontium, are used.
As discussed before, the assumptions influence the interpretation of the data.
There are three main assumptions that must be made to accept radiometric dating methods.
For since the fathers fell asleep, all things continue as they were from the beginning of creation.” For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water, by which the world that then existed perished, being flooded with water.
Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.
