Radioactive dating middle school

To the contrary, the rocks could still only be a few thousand years old.

The radioisotope methods, long touted as irrefutably dating the earth's rocks as countless millions of years old, have repeatedly failed to provide reliable and meaningful absolute ages for Grand Canyon rock layers.

Both laboratories use standard, best-practice procedures on state-of-the-art equipment.

The model K-Ar ages for each of the samples ranged from 405.1±10 Ma to 2574.2±73 Ma.

Yet the RATE research has uncovered much evidence, including the patterns of these discordances between the "dates" from the different radioisotope systems, For example, if accelerated radioisotope decay occurred, then alpha-decaying radioisotopes would yield older isochron "ages" than beta-decaying radioisotopes, which is exactly the pattern in the Brahma amphibolites (see diagram above).

Among these metamorphosed volcanic strata are amphibolites, belonging to the Brahma Schist.Metamorphic rocks are not always easy to date using radio-isotopes.Results obtained usually signify the "date" of the metamorphism, but they may also yield the "age" of the original volcanic (or sedimentary) rock.These were originally basalt lava flows several meters to tens of meters thick.In some outcrops pillow structures have been preserved, testimony to the basalt lavas having originally erupted and flowed under water onto the Creation Week ocean floor.
