Domain structures in rutile in ultrahigh-pressure metamorphic rocks from Dabie Mountains, China
摘要
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 0.753 nm (3d011) has tetragonal symmetry, cell parameters a=3a0
