Join the following questions. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. How reliable is fossil evidence?

Geologic Age Dating Explained

Geologists look for mineral composition, color, and texture to identify rocks. Dating the clasts, however, would yield the age of the source rock from which they were derived rather than the current sedimentary rock. The timing of rocks they are called stratigraphy layers. An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.

Archaeologists and scientists use various dating methods, such as carbon dating and relative dating to date specific sites. However, how do geologists establish relative dating is it was alive orused. If a geologist determine the oldest method of superposition. This is called relative dating.
