有关中元古界碧口岩群的成岩构造环境及中元古代碧口地体构造属性长期存在争议。本文综合火山岩、硅质岩所反映的构造信息，认为碧口地体中元古代曾发育过裂谷-有限洋盆构造环境，是在扬子陆缘基础上伴随元古代仰展构造作用发展和演化的。
The diagenetic tectonic environment of the Mesoproterozoic Bikou Group and the structural properties of the Mesoproterozoic Bikou terrane have long been in dispute. Based on the tectonic information reflected by volcanic rocks and cherts, this paper argues that the Proterozoic metamorphic rift valley-limited ocean basin environment in the Bikou terrane developed and evolved of.
