Geochemical and palaeontological evidence for the definition of the Silurian/Devonian boundary in the Changwantang Section, Guangxi Province, China [PDF]
Estonian Journal of Earth Sciences, 2015 Southern Guangxi Province is one of the important areas for the study of the Silurian/Devonian boundary (SDB) in South China. Despite attempts to define the exact level of the SDB in the Yulin (Guangxi Province) area using biostratigraphy, no consensus ...

A bio-chemostratigraphical test of the synchroneity of biozones in the upper Silurian of Estonia and Latvia with some implications for practical stratigraphy [PDF]
Estonian Journal of Earth Sciences, 2015 The paper discusses the reliability of different biozones in terms of their synchroneity when crossing facies boundaries within a sedimentary basin. Graptolite biozones are the most trusted ones, but also biozones based on conodonts, chitinozoans and ...
