What is the issue or problem addresses in your research?

It addresses carbon and strontium isotope composition and comparison of Lower Triassic marine carbonate rocks from Southern Longmenxia section in Guang'an, Sichuan Basin.

What methodology did you use in your research?

Thin-section observation, cathode luminescence analysis, and carbon and strontium isotope measurements. For that, the samples were crushed into <200 mesh and three splits were made for each. The splits were for element concentration, carbon-oxygen-isotope and 87Sr/86Sr measurements respectively.

What are the purpose/rationale and implications of your research?

The Permian-Triassic transition was characterized by dramatic changes in Earth's biosphere, atmosphere, lithosphere and oceans, with the largest biotic crisis in the Phanerozoic history commonly referred to as end-Permian mass extinction (EPME) and broadly coincident eruption of large igneous provinces (LIPs).However, the ultimate driving factor behind these behaviors and the cause-and-effect relationships among them are strongly diverging.
