According to the HRTEM study, the UHP jadeite-quartzite mineral (Rutile, TiO2) in Anhui Province, Dabie Mountains, China, has ultrastructures such as [011] two-dimensional commensurable modulated structures or superstructures, [011] twin domain structures, dislocations and crystal deformations. The SAED patterns and HRTEM images indicate the existence of the deformations and stacking faults on the interface of [011] twin crystal of rutile and its two-dimensional commensurate modulated structures with repetition period 0.753m (3d011) has tetragonal symmetry, cell parameters a=3a0=1:377nm (a0=0.459nm), c=c0=0:3nm. The modulated structures of rutile were probably caused by the isomorphic replacement of Ti4
