Answer:
Potassium-argon dating can be used for the determination of Absolute day of the rock that dates from 200,000 years.
Explanation:
Potassium-argon dating methodology that can be used for dating very ancient Archaeological materials. This method is used by geologists to date rocks that are 4 billion years old. The radioactive isotope of Potassium 40 (K-40) decays into the gaseous Argon (Ar-40).
The date on which the rocks were formed can be determined by comparing the ratio of Potassium 40 to gas Argon 40 in the volcanic rock sample along with rate at which K-40 is decayed.
