Abosolute dating

What is more, we can measure the rate of spreading directly by GPS, SLR, and VLBI.This means that if we didn't have any other way of doing absolute dating, we would as a first approximation take the age of basalt on a spreading sea floor to be the distance from the rift divided by the rate of spreading.

In this article I shall define absolute dating, and shall discuss the conditions that we would require to use a geological process as the basis for absolute dating.There's a small amount of radioactive carbon-14 in all living organisms.When they die no new carbon-14 is taken in by the dead organism.For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.
