Shallow-water hydrothermal venting linked to the Palaeocene–Eocene Thermal Maximum
International audience Abstract The Palaeocene–Eocene Thermal Maximum (PETM) was a global warming event of 5–6 °C around 56 million years ago caused by input of carbon into the ocean and atmosphere. Hydrothermal venting of greenhouse gases produced in contact aureoles surrounding magmatic intrusions...
