Carbon dating margin of error

The isochron techniques are partly based on this principle.The use of different dating methods on the same rock is an excellent way to check the accuracy of age results.Several hundred laboratories around the world are active in radiometric dating.Their results consistently agree with an old Earth.A recent survey of the rubidium-strontium method found only about 30 cases, out of tens of thousands of published results, where a date determined using the proper procedures was subsequently found to be in error.One question that sometimes arises here is how can scientists assume that rates of radioactivity have been constant over the great time spans involved.The differences actually found in the scientific literature are usually close to the margin of error, usually a few percent, not orders of magnitude!Vast amounts of data overwhelmingly favor an old Earth.

Essentially all of these strongly favor an old Earth.

Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.

    Aug 13, 2016. It may be, of course, that this is historical error rather than error in the radiocarbon dating method. Since then, evidence has been amassed showing that many of the “known historical dates” were wrong by a significant margin.
