Age earth radiometric dating
Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older.But even if it is true that older radiometric dates are found lower down in the geologic column, which is open to question, this can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later.Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.This calls the whole radiometric dating scheme into serious question.The 4-part dialog (essay review, response, and replies) is in Perspectives on Science and Christian Faith, the peer-reviewed journal of ASA.
This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.
Lava erupting earlier would come from the top of the magma chamber, and lava erupting later would come from lower down.
A number of processes could cause the parent substance to be depleted at the top of the magma chamber, or the daughter product to be enriched, both of which would cause the lava erupting earlier to appear very old according to radiometric dating, and lava erupting later to appear younger.
" — and these sources of heat by themselves (even if only one or a few of them occurred, even without rapid radioactive decay) would boil away all of the ocean water, and then it would take millions of years for earth to cool. In Assessing the RATE Project, Randy Isaac describes the current situation: "The authors admit that a young-earth position cannot be reconciled with the scientific data without assuming that exotic solutions will be discovered in the future.
No known thermodynamic process could account for the required rate of heat removal nor is there any known way to protect organisms from radiation damage. Yet they are so confident that these problems will be resolved that they encourage a message that the reliability of [their young-earth interpretation of] the Bible has been confirmed." Here are two evaluations of proposed young-earth solutions for the problem of overheating: • Flaws in a Young-Earth Cooling Mechanism by Glenn Morton & George Murphy • Nonexistence of Humphreys’ “Volume Cooling” for Terrestrial Heat Disposal by Cosmic Expansion by J.
