What the hell had that to do with the man's science on radiohalos?

[evolution] and its shoddy tactics 2009

I can point to a single example, the RATE project of ICR helium in zircon, radiohalos, carbon in diamonds, etc.

Another outcome of this research was the discovery of plentiful Po radio-halos in metamorphic rocks.6 Such a finding was predicted, because hydrothermal fluids are generated in water-saturated sedimentary rocks as they become deeply buried, helping to transform them into regional metamorphic complexes.7-9 Thus it was argued that the same hydrothermal fluid transport model could likewise explain the formation of Po radiohalos in those regional metamorphic rocks where an adequate supply of U-decay products occurred.10

As can be readily seen in figure 1, whereas seven of the samples averaged around 30 Po radiohalos each, the two samples straddling the staurolite isograd contained 177 and 147 Po radiohalos respectively.

Such mineral reactions have been studied in laboratory experiments and in them water is often a by-product.11 At the temperatures of these metamorphic processes such water would become hydrothermal fluids capable of transporting any U-decay products from nearby zircon grains and depositing Po in biotite flakes to form Po radiohalos.

These would have been ideal conditions for the generation of Po radiohalos in these metamorphosed sandstones, if Po radiohalo formation does indeed occur as described by the hydrothermal fluid transport model.

In continued research, a test of this Po radiohalos formation model in metamorphic rocks was proposed.

Therefore, if hydrothermal fluids had been generated by the metamorphism, according to the hydrothermal fluid transport model for Po radiohalo formation, those hydrothermal fluids should have transported the Po diffusing out of the zircons into the biotite flakes, where it should have formed Po radiohalos.
