Other articles where absolute dating is discussed: although relative ages can generally be established on a local scale, the events recorded in rocks from different locations can be integrated into a picture of regional or global scale only if their sequence in time is firmly established the time that has. There are no temporal limits to relative dating, for the methods are equally applicable to the dating, say, of proterozoic surfaces as of those of pleistocene age the disadvantage of such methods is that the necessary evidence is frequently either not preserved or not exposed the so-called 'absolute' (physical, numerical).
