Sedimentary rock age dating
For example, uranium will radioactively decay through a series of steps until it becomes the stable element lead. The original element is referred to as the parent element (in these cases uranium and potassium), and the end result is called the daughter element (lead and argon).The straightforward reading of Scripture reveals that the days of creation () were literal days and that the earth is just thousands of years old and not billions.Therefore, there are several assumptions that must be made in radioisotope dating.Three critical assumptions can affect the results during radioisotope dating: Radioisotope dating can be better understood using an illustration with an hourglass.For example, the remaining radioactive parent material will decrease by 1/2 during the passage of each half-life (1→1/2→1/4→1/8→1/16, etc.).Half-lives as measured today are very accurate, even the extremely slow half-lives.That is, billion-year half-lives can be measured statistically in just hours of time.The following table is a sample of different element half-lives.
Since God is the Creator of all things (including science), and His Word is true (“), the true age of the earth must agree with His Word.
Provided there has been no sample contamination or disturbance of the U–Pb system, the youngest igneous crystallization dates obtained on detrital zircons from a sedimentary rock sample will provide a maximum age for sediment deposition.
Maximum depositional ages so obtained are comparable to minimum ages determined from the dating of cross-cutting dykes, or of metamorphic or diagenetic minerals, but a significant advantage of this approach is that detrital zircons are virtually ubiquitous in clastic sedimentary rocks.
Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements.
There are certain kinds of atoms in nature that are unstable and spontaneously change (decay) into other kinds of atoms.
