Does carbon dating work for 6 billion years
Evidence from radiometric dating indicates that Earth is about 4.54 billion years old.
The most common radioactive element in granite is Uranium-238.
The geological time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time, and is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.
The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy.
And it does not work on rocks or thoroughly mineralized fossils; it is only useful for relatively well-preserved organic materials such as cloth, wood, and other non-fossilized materials.
Other methods must be used to estimate the age of rocks and minerals.This clock representation shows some of the major units of geological time and definitive events of Earth history.The Hadean eon represents the time before fossil record of life on Earth; its upper boundary is now regarded as 4.0 Ga (billion years ago).While these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it).
