Abstract: With the rapid growth of the number of students, professional researchers and published papers and books in the field of tectonics and structural geology in China as well as the introduction of newly created terminology to the subject area, the phenomena of misused, abused and inaccurate used terms have frequently appeared. In this paper, the meanings of some terms are analyzed and their applications are discussed in six aspects for reference:①terms with extensive epitaxy; ②different terms with related meaning; ③ terms which fail to meet structural geology logic; ④terms which are not suitable for actual geological condition; ⑤terms with similar "shapes"but different"meanings"; ⑥ terms which are likely to be abused. The purpose of this paper is to meet the needs of the smooth exchange between peers and to promote the development of structural geology.
