Quote: EVERY TIME a piece of non-fossilized organic matter, be it a dinosaur bone, wood, oil or coal, is retrieved from a stratum that is believed to be several millions or hundred of millions of years old, it shows traceable amounts of Carbon-14
PS welcome to A2K. , but, having said that,As a geologist who employs geochronological labs alot any fool that would use C14 in deep time measurements or anything older than about 50K years would be wasting precious resources (enter "BUCKS"). We know better than that.If I were the contractor and some yahoo came up with a dino bone and wanted to do C14, he,or she would be redoing their resume but quick.
THERE ARE SOME GOOD R/ISOTOPE TECHNIQUES FOR DEEP TIME
K/A is a long lived isotope series that can be used in deep time. However, sampling of remobilized mantle material for K/A means that one has faith that the A hasnt been volatilized in the mineral content. Argon is a GAS and elutes real easily.We would not use K/A in active volcanic belts, or very recent metamorphic events (like the Rockies)
So for real deep time we use a bunch of other isotope tricks. Neodymium /Samarium (Nd/Sm),Lutetium/Hafnium(Lu/Hf), Rhenium /Osmium (Re/Os) and several variations of Uranium/Thorium/lead 210 (U238/235,/Th208/Pb210/207/208) {Theres about 4 variations in there}.
We know that, from crustal abundance and meteoritic elements that elemental abundances for anything higher Atomic No than Zirconium (40) is about the same. So the differences we see are due to isotopic decayand final ratios. These are calibrated against meteoritic standards (CHUR;BABI)
If we were doing deep time fossil and sed/petrology determinations , wed be looking at heavy minerals and their contents of the above radioisotopes. Wed be looking for, primarily ZIRCON CRYSTALS.
Now, we get mistakes in all these because the ratios can change in metamorphic events that release several isotopes. But this is good because we can compare age differences of when tectonic plates started moving about by the metamorphism and lost isotopes in the smooshed minerals and the zircons.
So, yes we get different dates , but they surround geologic events, after all the planet wasnt laid out in 7 days , it cooled and an engine started the plates moving about. Radioisotope dating has been clustreing about a statistical norm age for many events (eg Grenville orogeny, Taconic, Antler etc). The answers that you mostly made up are probably gotten from some Creationist site where they dont wanna delve too deeply lest they be embarrased with what is found.
Please dont believe all of Duane Gish's minions crap. There are a few good geochemists in the ICS whove just turned to the "dark side" and gone Creationist , so theyve dropped their science and become hucksters for Jesus. There are many scientists who, while not diddling with the data and being scientifically honest, are still deeply religious.A few are actually clergy
