The strata in this section cover three lithostratigraphic units, seven conodont zones, five ammonoid zones and three bivalve zones. Two normal and two reversed magnetic polarity zones as well as the cyclic sequences corresponding to the Milankovitch climate periods driven by the Earth's orbit are well recognized in the lower part of the section.

该剖面包括3个岩石地层单元、7个牙形石带、5个菊石带、3个双壳类带；在剖面下段地层中识别出2个正向磁性带和2个反向磁极性带；与地球轨道天文周期相对应的Milankovitch气候沉积旋回也可以明确地辨认；碳氧同位素δ13C演变呈现两次大的旋回。

The examination of many infected roots canal and LPS of oral anaerobe in apical cyst shows that LPS is closely related with the occurrence and clinic symptoms of endodontical disease and periapical disease.
