Fission tracks are most often caused by the spontaneous fission of the parent Uranium-238 atom into two daughter atoms of palladium-119.

The solar estimate was based on the idea that the energy supply for the solar radioactive flux is gravitational contraction.

Chemical etching of polished internal surfaces of these minerals reveals spontaneous fission tracks, and the track density can be determined.

Because etched tracks are relatively large (in the range 1 to 15 micrometres), counting can be done by optical microscopy, although other imaging techniques are used.

(removal of material by solution) of the host substance with a suitable chemical reagent; the leaching process allows the etched fission-track pits to be viewed and counted under an ordinary optical microscope.

The amount of uranium present can be determined by irradiation to produce thermal fission of .

Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records.
