  There has been considerable interest in recent experiments on iron nuclear
disintegrations observed when rocks containing such nuclei are crushed and
fractured. The resulting nuclear transmutations are particularly strong for the
case of magnetite rocks, i.e. loadstones. We argue that the fission of the iron
nucleus is a consequence of photo-disintegration. The electro-strong coupling
between electromagnetic fields and nuclear giant dipole resonances are central
for producing observed nuclear reactions. The large electron energies produced
during the fracture of piezomagnetic rocks are closely analogous to the
previously discussed case of the fracture of piezoelectric rocks. In both cases
electro-weak interactions can produce neutrons and neutrinos from energetic
protons and electrons thus inducing nuclear transmutations. The electro-strong
condensed matter coupling discussed herein represents new many body collective
nuclear photo-disintegration effects.
