Blocking temperature radiometric dating

This reproductive die-off meant a “total failure” of murre reproduction that year…

“The reproductive die off is something we’ve never seen in murres before, widespread.

"After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide. If a material that selectively rejects the daughter nuclide is heated, any daughter nuclides that have been accumulated over time will be lost through diffusion, setting the isotopic "clock" to zero.

The temperature at which this happens is known as the closure temperature or blocking temperature and is specific to a particular material and isotopic system.

For example, if most of the radioactive decay implied by fission tracks or quantities of daughter products occurred over the year of the Flood, the amount of heat generated would have been excessive, given present conditions.Even where the ten systems may be present, geologists recognize individual systems to be incomplete.The entire geologic column, composed of complete strata systems, exists only in the diagrams drawn by geologists!Some of the information is technical and I have tried to provide references and links for the more difficult portions of the text in order to help any reader go beyond the material presented here.There is no shortage of criticism of the radiometric dating technique by young Earth creationists.
