    Shallow-water hydrothermal venting linked to the Palaeocene–Eocene Thermal Maximum

    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 p...

    Volcanic Margin Concepts

    Volcanic margins are part of a tectono-magmatic system in which the margin fonnation depends on lithospheric and asthenospheric properties before, during and after continental breakup. Whether a volcanic margi...
