How to calculate age using carbon dating Slave dating sites
Radiocarbon ages do not increase steadily with depth, as one might expect. In other words, the concentration of carbon-14 is unexpectedly low in the lower organic layers.
As one moves to higher and higher layers, this concentration increases, but at a decreasing rate.
They concluded that the helium in the rock was 100,000 times more plentiful than it should have been if the rocks were really 1.5 billion years old.
The assumption usually made, but rarely acknowledged, is that the ratio of carbon-14 to carbon-12 in the atmosphere before the industrial revolution has always been the sameabout one in a trillion.
Half of it will decay in about 5,730 years to form nitrogen.
Half of the remainder will decay in another 5,730 years, and so on.
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.
The helium still locked in the samples was studied as well as the rate at which the helium diffused from the rock.
