Another factor in this direction is that older glauconies have more time to absorb argon 40.The only correlation I know about that has been studied is between K-Ar and Rb-Sr dating on precambrian rock.If this condition does not hold, invalid ages and intercepts are obtained.If we can assume the axis of rotation or crust of the earth are in motion for some reason, this could cause an apparent change in the length of the year. One way to infer how the atmospheric concentration of carbon-14 changed in the past is by tree-ring dating.
Corliss, Unknown Earth (Glen Arm, Maryland: The Sourcebook Project, 1980), p.However, this test would not indicate excess argon 40 present during cooling. This implies that several geological periods are missing, with only a lava flow to show for it.Note that since well-preserved fossils imply rapid burial, and many fossils occur together, many creatures must have died at about the same time.The flatness means that the lava is a contiguous mass, and can still be reached from the hot magma by a continuous path of hot rock.This is formed when lava is sticky and bubbles of gas in it explode.
In addition, some kinds of rocks are not considered as suitable for radiometric dating, so these are typically not considered.
