In view of geological records preserved from different regions of the world are not identical, it's suggested that, when correlating the Ordovician-Silurian boundary, at the global boundary stratotype section, the FAD of N. persculptus be selected as the biomark, the transgression event identical to the FAD of N. persculptus as the auxiliary physical mark and the mass extinction and chemical anomaly events respectively as the auxiliary biomark and chemomark. In some regions with few graptolite, the Ordovician-Silurian boundary should be indicated by the auxiliary marks, such as the transgression event, mass extinction or chemical anomaly event, with the other fossil such as conodont nearest to other geological events as the provincial biomark for correlation. In other regions with much stratigraphic hiatus originated from the regression, the Ordovician-Silurian boundary should be marked by the regression-transgression event nearly relevant to the N. persculptus Zone.

鉴于不同地区留下的地质记录不完全相同，奥陶/志留系界线对比方法不同：在界线层型剖面上，以N.persculptus的首现为生物标志，以与之基本一致的海侵事件为辅助的物理标志，以生物集群绝灭事件和化学异常事件为辅助的生物和化学标志；在笔石极不发育的地区，则以海侵事件、生物绝灭事件或化学异常事件为辅助标志，以与其相距最近、并且具有区域对比性的其它门类化石作为界线对比的生物标志；对于由于海退事件所造成地层缺失很多的地区，则以海退/海侵事件作为划分界线的物理标志，并以相映的海侵事件的开始作为奥陶/志留系的分界。

According to the characters of organic maceral, organic type, biomarker,it can be divided to five types of sedimentary facies: unrest restricted sea graptolite facies, alluvial restricted sea, carbonate mesa algal deposit facies, mud mesa algal deposit facies and deep water shelf algal deposit facies.

根据烃源岩有机显微组分、有机质类型、生物标志物及成烃能力等特征划分出五类沉积有机相，即动荡局限海笔石相、滞流局限海笔石相、碳酸盐台地藻积相、泥质台地藻积相和深水陆棚藻积相。

Persculptus to Parakidograptus acuminatus Zones, could be recognized during the interval. In addition, the abundance changes of the radiolaria at the Goujiaya and Datangkou sections were coincided with the sea-level changes, and correlatable with the synchorous 5 fluctuations of the sea-level in North America and Africa. So above-mentioned 5 cycles could represent the eustasies during the latest Ordovician to the earliest Silurian.

在这2个剖面上，放射虫丰度变化也表现出相似的规律，与笔石和腕足类的形态、分异度和丰度变化所反应的海平面升降大体一致，和北美、非洲同期海平面的5次波动可以对比，据此指出，以上5次海平面旋回代表了晚奥陶世晚期至志留纪初期全球性海平面变化。
