Article Synopsis
- The study focuses on the Siberian Traps magma and its role in creating a sub-volcanic plumbing system, leading to the formation of sills in the Tunguska Basin that release gases during metamorphism.
- The findings reveal that sills over 100 meters thick are common, especially in Cambrian evaporites, with an average thickness of 115-130 meters.
- Thermal modeling indicates these sills can generate significant amounts of CO₂, reinforcing the idea that sub-volcanic activity contributed to environmental changes during the End-Permian crisis.
