Radiocarbon relationship can be utilized on sediments or sedimentary rocks that comprise carbon, however it can’t be used on supplies older than about 60 ka. The methodology of utilizing radioactive 
decay to determine the age of rocks is identified as radiometric dating. Cation-ratio relationship is used so far rock surfaces such as stone artifacts and cliff and ground drawings. It can be utilized to obtain dates that might be unobtainable by more standard methods such as radiocarbon dating. Radioactive courting is one other methodology of figuring out the age of, particularly, rocks and fossils. It determines the absolute age of the geological supplies or fossils.

ages. Radiation, which is a byproduct of radioactive decay, causes electrons to dislodge from their regular position in atoms and become trapped in imperfections within the crystal construction of the fabric. Dating methods like thermoluminescence, optical stimulating luminescence and electron spin resonance, measure the buildup of electrons in these imperfections, or “traps,” within the crystal construction of the fabric.
