Absolute dating radiometric dating
Perhaps you have heard of Ice Man, a man living in the Alps who died and was entombed in glacial ice until recently when the ice moved and melted.
The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.
The calculation are based on the percentages of parent, and daughter elements.
These calculations are based on geological assumptions of uniform process, the lack of erosion of either the parent or daughter elements.
Fossil Frustrations New Scientist Nov 1983 " Ager Derek I think of no cases of radioactive decay being used to date fossils.
" Ultimately fossils are dated using Darwinian evolutionary theory.
The boat of a pharaoh was discovered in a sealed crypt and reassembled in a museum near the pyramids (see Fig. The age of our galaxy and earth also can be estimated using radioactive dating.This is based on the concept that, in a normal depositionary sequence, the deepest layers are also the oldest.absolute dating is based on calculations of the age of rock strata based on half lives of minerals, relative dating is based on the assumed age of fossils found in the strata and the laws of super imposition. The absolute dating is based on calculation of half life.The fossils which are buried deep inside the earth are more ancient.While in the absolute dating, isotopes of carbon are used for dating fossils.
