* This TPOD on Libya's Kebira Crater mentioned the possibility that Iridium was transmuted:

* On the Transmutations thread I had a post called From Lead into Gold and Iridium at
http://thunderbolts.info/wp/forum/phpBB3/v ... t=45#p4915
* I mentioned in the post a very possible transmutation route for Uranium and Thorium to Lead [rather common elements] and from Lead to Gold, Iridium and Platinum. Here's the latter portion. This quote is slightly modified.
[b = beta-; a = alpha-particle {beta is an electron that combines with a proton to form a neutron, alpha is a Helium nucleus of 2 protons and 2 neutrons}]:
Pb82:208 -b= Bi83:208
Bi83:208 -b= Po84:208
Po84:208 -a= Pb82:204
Pb82:204 -a= Hg80:200
Hg80:200 -Li3:7= Ir77:193.
- Iridium then can be fused with Hydrogen or Helium to make Platinum or Gold:
Ir77:193 +H1:1= Pt78:194;
Ir77:193 +He2:4= Au79:197.
- So it seems possible that the ancients may have witnessed natural transmutation of Lead into Gold, Iridium and Platinum.
