双晶面-
变形双晶面分别为（100）和（010）。表明该类金红石晶体曾遭受过强烈的应力作用，推测它们可能是在大陆板块俯冲或折返过程中形成中发育的。
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 .
