Abstract
It is estimated that the uranium-oxygen bond dissociation energy (D U 4 +−0 =1465.38kJ/mol) is higher than silicon-and aluminium-oxygen bond dissociation energies (DSi4 +−0 =1264.41 kJ/mol and DAl3 +−0 =1105.32 kJ/mol). During the process of magmatic differentiation with increasing degree of polymerization for silicon-oxygen complex ion, uranium in granitic melts tends to combine with oxygen to form the coordination polyhedron [UO 2x−nx ] and to occur in the form of nuclei and crystals of uraninite, as has been demonstrated by the induced fission-track study of quartz syenite from Huangmeijian.
