%X Detailed TEM investigations present the ultra-fine microscopic textures of rutile in rutile eclogites of Maobei, Su-Lu UHP terrane. There are two types of rutile in investigated samples. One type rutile (Rt(A)) associates with garnet and omphacite. The dense defects, modulated texture and regular oriented nanometer-size deformed twins are discovered. Two group twins in the rutile are observed which planes parallel to (100) and (010) respectively, indicating a strong strain effect on the rutile crystals, and may intimately relate to the subduction, exhumation and subsequent continental collision. The other type rutile (Rt(B) ) is included in the garnets or omphacites. The crystal of later type is well preserved in the host minerals, and has not undergone crystal distortion during exhumation of subducted slab.
