They as a whole reached high amphibolite facies to granulite facies with characteristic equilibrium assemblage of peak stage Sil+Grt+Bt±Crd+Kfs+Pl+Qtz.

荆山群变质岩系经历了三幕变形、六幕变质重结晶作用，峰期形成Sil+Grt+Bt±Crd+Kfs+Pl+Qtz特征平衡组合，变质程度达高角闪岩相-麻粒岩相。

During geological mapping of Xainza County in 2000, Tetragraptus approiimatus, the typical one of graptolite belts which cosmepolitically distributed in the Arenigian of Early Ordovician, was collected from the so-call Pre-Sinian Nianqingtanggula Group. So there is developped the Early Ordovician sediments and we have established Zakang Formation and Taduo Formation which perfected the Plaeozoic sequences in northern Tibet.

申扎地区1/25万区域地质调查工作中，在原归属为前震旦系念青唐古拉群的一套浅变质岩中发现了世界性分布的下奥陶统阿雷尼格阶最底部笔石化石带代表分子Tetragraptusapproximatus，首次确定了藏北地区有早奥陶世沉积地层的存在。

Near the contact boundary there exists a kind of metamorphic rock known as hornfels. It is resulted from the contact metamorphism when magma comes in contact with the sedimentary rocks and heats and squeeze s them.

在二者接触界线附近发育着一种叫角岩的变质岩，角岩的形成是由于岩浆人侵与周围沉积岩接触时所产生的热量和压力致使原岩发生变化而成。
