- Abstract:
- The eruption of flood basalt provinces such as the end-Permian Siberian Traps have been linked to significant perturbations of the carbon cycle, global warming, ocean anoxia and large-scale extinctions in the geological past. The carbon output of large flood basalt eruptions is poorly constrained. We propose a proof-of-concept study of gas release from lava flows, tephra and sills of the Siberian Traps. We will use a novel microanalytical study of melt inclusions and fluid bubbles to constrain the volatile budget associated with the magmatism, incorporating gas release not only from lava and unerupted magma but also building on new studies that have indicated a role for a contribution of volatiles from contaminating sediments. These gas fluxes will form key inputs for future improved models of climatic and biotic impact associated with flood basalt events. We anticipate this work will lead to a larger study that will examine the importance of large igneous provinces and modern magmatic volatile budgets in environmental change.
