In order to study the relationship between the Large Igneous Province volcanism with OAE 1d. We used the mercury geochemical analyses, including element content, isotope values, and other related element and organic matter content data to study the mid-Cretaceous, especially Albian-Cenomanian, sediments in southern Tibet, which was located at the northern margin of the Indian plate at ~100 Ma. We herein provided all these geochemical data and some analytical methods.
