The scheme has a range of several hundred thousand years.Also, an increase in the solar wind or the Earth's magnetic field above the current value would depress the amount of carbon-14 created in the atmosphere.

The carbon-14 ends up as a trace component in atmospheric carbon dioxide (CO2).

Plants acquire it through photosynthesis, and animals acquire it from consumption of plants and other animals.

Partially reset and unreset material lies on either side of this zone of young ages.

Although some thermochronometric ages predicted by our fault-bend-fold model are similar to those predicted using a 1-d thermal model, the patterns of ages are markedly different.

Our model links the kinematic structural model to a finite-element advection–diffusion thermal model to track the cooling history of material exhumed by erosion during thrust faulting and fault bend folding.

We use the cooling histories to model fission track annealing and He retention and predict zircon and apatite fission track and apatite (U–Th)/He thermochronometric ages.

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.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

It is accompanied by a sister process, in which uranium-235 decays into protactinium-231, which has a half-life of 34,300 years.

Closure temperatures are so high that they are not a concern.

We will deal with carbon dating first and then with the other dating methods.
