摘要: 主要运用构造筛分与成生联系解析的综合研究方法,在鄂西黄陵背斜地区,进一步厘定了阜平、吕梁(兴山)、四堡(神农)、晋宁(花山)等构造运动及相关的岩浆、变质事件。建立了黄陵(崆岭)杂岩时序以及由近东西向、北东向、北西向三类古构造带复合的前南华纪古构造格架,提出了定型于四堡期的圈椅淌滑脱构造系。

Abstract: By using such integrated research methods as the tectonic sieving and genetic relation analysis, this paper further defines the Fuping (Wutai) movement, Lüliang (Xingshan) movement, Sibao (Shennong) movement and Jinning (Huashan) movement and their related magmatic and metamorphic events in the Huangling anticline, western Hubei.The authors have established the pre-Sinian time sequence of the Huangling (Kongling) complex and paleostructural spatial framework formed by compounding of nearly E-W-, NE-and NW-trending palaeostructural belt.This paper also firstly proposes the Quanyitang detachment structural system formed in the Mesoproterozoic (Sibaoan).
