| 摘 要： | 晚元古—早古生代北秦岭以早元古宙秦岭群为中央隆链,其南北两侧对称地发育着两条裂陷槽。南裂陷槽沉积了以丹凤群(李子园群)为代表的火山-沉积岩系,北裂陷槽沉积了以斜峪关群(二郎坪群)为代表的火山-沉积岩系。本文主要讨论北裂陷槽的沉积变质作用及其构造演化。

| Abstract: | Taking the Qinling Group as the central uplift, the two aulacogens were symmetrically growing in the north-sourth sides during the Upper proterozonic-Palaeozonic Era. The Danfeng Group was deposited in the sorth-aulacogen, and the Xieyuguan Group (Erlangping Group) in the north-aulacogen, which is called the volcanogene sedimentary rock series and represented the rock association in the north-aulacogen. The meta-morphism and tectonic evolution of these rock series are discussed in this paper. |
