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。

Based on plentiful isotopic dating data and geological studies, the authors, in this paper, discuss the geological meanings of the two isotopic ages given by Lapierre et al., and conclude:① Mesozoic volcanic activities in Zhejiang are most frequent in 130~83 Ma, that is, from the early to late Cretaceous but not the late Jurassic;② The Jiande and Moshishan groups are nearly in the same period and not in an upper—lower stratigraphic relationship with each other;③ The period of 110~100 Ma is a transitional stage from the early high-K calc-alkaline dacite—rhyolite associated with diorite—granodiorite) to the late basalt—rhyolite(associated with K-feldspar granite—alkali granite).
本文就Lapierre等文中124 Ma和97 Ma两个年龄的地质意义、幕次划分以及浙西与浙东火山岩时代对比作出评论,并厘定浙江中生代火山岩时代归属,提出:①浙江中生代火山活动时代为132~83 Ma;②浙西建德群与浙东磨石山群火山岩并不存在上下关系,地质接触关系、古生物组合和大量同位素定年数据都不支持Lapierre等的浙西与浙东火山活动幕次的对比方案;③ 110~100 Ma为早期高钾钙碱性英安岩—流纹岩(伴生闪长岩—花岗闪长岩)向晚期玄武岩—流纹岩(伴生钾长花岗岩—碱性花岗岩)过渡的转折期。

Tracksites occur exclusively throughout several stratigraphic levels of a thick, mixed-affinity, lagoonal-terrestrial sequence known as the Upper Red Formation in north central Iran and within a continental series deposited in the southern Caspian area in north of the country. The tracks from the Upper Red Formation are mainly artiodactylan type, attributed to several gazelle sized species due to their small size, and other tracks attributed to small, medium and large sized mustelid and felid carnivores.
