Is carbon dating appropriate for measuring the age of materials

Radiocarbon dating is appropriate for measuring the age

because carbon-14 decays relatively rapidly compared to other isotopes, it can only be used to date things that are less than 60,000 years old. 4:radiometric dating depends on the chemistry and ratios of different elements. the supposed age of “index fossils” is based on how long these 19th century evolutionists believed one kind of animal would take (somehow) to “evolve” into a different kind of animal. a very small percentage of the carbon plants take in is radioactive c-14. measuring the ratio of uranium to lead can have a margin of error as small as 2-5%. addition to the above assumptions, dating methods are all subject to the geologic column date to verify their accuracy. for an example of how geologists use radiometric dating, read on:a geologist can pick up a rock from a mountainside somewhere, and bring it back to the lab, and separate out the individual minerals that compose the rock. there are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate. there are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate. we have also obtained a very similar age by measuring pb isotopes in materials from earth. this is why crystals are good for radiometric dating: the atoms in a crystal are extremely efficiently packed, and it's very difficult to get anything into a crystal such as a contaminant by any means short of destroying the crystal and re-growing it anew. one gram of carbon from living plant material causes a geiger counter to click 16 times per minute as the c-14 decays.-14 is the most commonly used isotope for dating organic material (plants, animals). when they die, they no longer acquire carbon-14 and so we can measure the decay of the isotope to determine when the plant or animal died. because carbon-14 decays relatively rapidly compared to other isotopes, it can only be used to date things that are less than 60,000 years old. reason we know that radiometric dating works so well is because we can use several different isotope systems (for example, uranium-lead, lutetium-halfnium, potassium-argon) on the same rock, and they all come up with the same age. also, techniques such as taking samples from multiple sections and dating with multiple isotopes, will help crosscheck/confirm the accuracy of the date.

we have dated meteorites using rb-sr, sm-nd, pb-pb, re-os, and lu-hf isotope systems and have obtained very similar ages. the fact that the age we calculate is reproducible for these different systems is significant. dating older objects, namely rocks, it is necessary to use other isotopes that take a much longer time to decay. the ratio of the parent to daughter then can be used to back-calculate the age of that rock. mathematical premise undergirding the use of these elements in radiometric dating contains the similar confounding factors that we find in carbon-14 dating method. know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes. from layers where dinosaurs are found carbon dated at 34,000 years old. would really be nice if geologists would just do a double blind study sometime to find out what the distributions of the ages are. billion years old, however, based on the ages of the zircon crystals within them. he would simply go to a chart that listed the geologic column by ‘ages’ and find the place where the index fossil appears, and thereby the geologists could tell the paleontologist how old his fossil was. the reason that i trust the accuracy of the age that we have determined for the earth (~4. anything older would have so little carbon-14 left that you couldn't accurately measure it. we assume that the earth is probably as old as the asteroids, because we believe the solar system to have formed from a collapsing nebula, and that the earth, being geologically active, has simply destroyed any older zircon crystals that would be its true age, but we can't really be certain. the so-called geologic column was developed in the early 1800s over a century before there were any radio- metric dating methods. if a date obtained by radiometric dating does not match the assumed age from the geologic column, the radiometric date will be rejected. carbon-14 dating has been used successfully on the dead sea scrolls, minoan ruins and tombs of the pharaohs among other things.. the global flood of 2,348 bc) as global catastrophes reset all the radiometric/atomic “clocks” by invalidating the evolutionist’s main dating assumption that there have never been any global catastrophes.

  • Is carbon dating appropriate for measuring the age of materials

    this technique looks good at first, carbon-14 dating rests on at least two simple assumptions. we assume that the earth is probably as old as the asteroids, because we believe the solar system to have formed from a collapsing nebula, and that the earth, being geologically active, has simply destroyed any older zircon crystals that would be its true age, but we can't really be certain. by measuring the parent isotope (radioactive) and the daughter isotope (radiogenic) in a system (for example, a rock), we can tell how long the system has been closed (in our example, when the rock formed). 5:radiometric dating is a widely accepted technique that measures the rate of decay of naturally occurring elements that have been incorporated into rocks and fossils. reason we know that radiometric dating works so well is because we can use several different isotope systems (for example, uranium-lead, lutetium-halfnium, potassium-argon) on the same rock, and they all come up with the same age. dating cannot be used on most fossils, not only because they are almost always allegedly too old, but also because they rarely contain the original carbon of the organism that has been fossilized. i do think that radiometric dating is an accurate way to date the earth, although i am a geochronologist so i have my biases. the problems inherent in radiometric dating often cause them to be so unreliable that they contradict one another rather than validating each other. by measuring the parent isotope (radioactive) and the daughter isotope (radiogenic) in a system (for example, a rock), we can tell how long the system has been closed (in our example, when the rock formed). there are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old. 4:radiometric dating depends on the chemistry and ratios of different elements. … in other words, radiometric dating methods are actually fit into the geological column, which was set up by [index] fossil dating over 100 years ago. i do think that radiometric dating is an accurate way to date the earth, although i am a geochronologist so i have my biases. the half-life of carbon-14 makes it unreliable for dating fossils over about 50,000 years old, there are other isotopes scientists use to date older artifacts. just this one fact totally upsets data obtained by c-14 dating. since you are exposed to the atmosphere and contain carbon, if you get oils from your skin onto an archeological artifact, then attempting to date it using radio carbon will fail because you are measuring the age of the oils on your skin, not the age of the artifact.-14 is the most commonly used isotope for dating organic material (plants, animals).
