One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.So, we have a “clock” which starts ticking the moment something dies.It makes no sense at all if man appeared at the end of billions of years.We will deal with carbon dating first and then with the other dating methods.Accordingly, carbon dating carefully applied to items from historical times can be useful.However, even with such historical calibration, archaeologists do not regard C produced and therefore dating the system.Anything over about 50,000 years old, should theoretically have no detectable C.That is, they take up less than would be expected and so they test older than they really are.

It does not give dates of millions of years and when corrected properly fits well with the biblical flood.Carbon has unique properties that are essential for life on Earth.Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc.These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification.

  1. Addition of this state-of-the-art instrumentation will allow the UT (U-Th)/He laboratory to engage in 4He/3He thermochronometry, analyze very young low He-yield volcanic samples and other low radiogenic samples (e.g., young magnetite), and also enter the world of He laser ablation measurements.
