Sourcing extraterrestrial Nuclear fuel

Hi Lucio,

Thorium is found in about the same concentrations as
Uranium. I'm not fully aware of how it is
concentrated though its use is far more limited.

My background studies were in paleo climatology and
deep mantle mineralogy including a case study of
armacolite FeTi2O5 and other iron titanium oxides.
They have no expansion coefficient due to reordering
of their internal entropy states and are thus a novel
material to use.

Unless you teach it is hard to get a job in this area.

Cheers Thor

What about Thorium? Does Thorium ore need the same
hydrological, tectonic and
volcanic processes to form, as in the case of Uranium
ore?

BTW, I am curious, your knowledge of Geology and
Mineralogy seems very deep.
(Or at least much deeper than mine. :-) Do you work in
those areas?
