Significance ofcollecting geological cores and samples from China’s “Golden Spikes” sections

As the only criterion of the global stratigraphic boundary, the establishment of the “Golden Spikes” is of great significance. The systemic collection, integration, and permanent storage of the representative geological cores and samples related to the “Golden Spikes” sections, are very important for preserving the data of the “Golden Spikes”, interpreting the scientific connotation of the “Golden Spikes”, as well as boosting the related follow-up research. Meanwhile, the comprehensive storage of the geological cores and samples can make it easy to do comparisons of the stratigraphic profiles in the same period to strengthen the position of the “Golden Spikes” as a global stratigraphic correlation standard. The geological cores and samples from the “Golden Spikes” sections can also play a model and exemplary role in geosciences teaching and science popularization, which can also be applied to scientific research, production and teaching.
