## 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).### Carbon-14 Dating

dating older objects, namely rocks, it is necessary to use other isotopes that take a much longer time to decay. measuring the ratio of uranium to lead can have a margin of error as small as 2-5%. 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. carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air. there are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate. i should mention that the decay constants (basically a value that indicates how fast a certain radioactive isotope will decay) for some of these isotope systems were calculated by assuming that the age of the earth is 4. you believe radiometric dating is an accurate way to date the earth? because geochronologists want to measure isotopes with different masses, a mass spectrometer works really well for dating things. could you also please explain further what radiometric dating is and the process to use it? most estimates of the age of the earth come from dating meteorites that have fallen to earth (because we think that they formed in our solar nebula very close to the time that the earth formed). in other words, we can predict the age of a rock within two million years out of two-and-a-half billion years. 2:yes, radiometric dating is a very accurate way to date the earth. 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. the fact that the age we calculate is reproducible for these different systems is significant. radiometric dating is the use of radioactive and radiogenic (those formed from the decay of radioactive parents) isotopes (isotopes are atoms of the same element that have different numbers of neutrons in their nuclei) to determine the age of something. the ratio of the parent to daughter then can be used to back-calculate the age of that rock. this belief in long ages for the earth and the evolution of all life is based entirely on the hypothetical and non-empirical theory of evolution.- How to write your first message on a dating site
## Carbon-14, Radiometric Dating - CSI

although the half-life of some of them are more consistent with the evolutionary worldview of millions to billions of years, the assumptions used in radiometric dating put the results of all radiometric dating methods in doubt. we have dated meteorites using rb-sr, sm-nd, pb-pb, re-os, and lu-hf isotope systems and have obtained very similar ages. 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. the older an object is, the less carbon 14 it contains. various confounding factors that can adversely affect the accuracy of carbon-14 dating methods are evident in many of the other radioisotope dating methods. billion years old, however, based on the ages of the zircon crystals within them. we have dated meteorites using rb-sr, sm-nd, pb-pb, re-os, and lu-hf isotope systems and have obtained very similar ages. dating older objects, namely rocks, it is necessary to use other isotopes that take a much longer time to decay.“one part of the vollosovitch mammoth carbon dated at 29,500 years and another part at 44,000. the decay constants for most of these systems have been confirmed in other ways, adding strength to our argument for the age of the earth. the age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating. could you also please explain further what radiometric dating is and the process to use it? 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. assert that generally speaking, 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. when scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age. 2:yes, radiometric dating is a very accurate way to date the earth.- How long to be friends before dating christian
