| 摘 要： | 依据龙门山中段映秀断裂带构造岩的宏观地质特征、显微构造及组构特征，论证了构造岩具有脆性和韧性两大类型，形成序次上为先韧性后脆性。映秀断裂带是在长期持续推覆作用下形成的一条脆、韧性道冲构造。文章还讨论了断裂带形成的构造环境和演化机制。

| Abstract: | Based on the macroscopic characteristics, microstructure and fabric of the tectonite in the Yingxin fault zone,this paper proves that there are two types of tectonite, i. e. the ductile toctonite and brittle tectonite and the ductile one was formed earlier and the brittle one later in the sequence of formation.The Yingxiu fault zone is a brittle and ductile thrust formed under a long-time napping. The paper also discusses the structural setting and the evolutionary mechanism of the Yingxiu fault zone. |
