Across the Arctic lies evidence for a massive past volcanic event, called the High Arctic Large Igneous Province (HALIP). This ancient volcanic event is particularly unusual in that it appears to have lasted for over 50 million years. Could a single deep-seated mantle plume cause such wide-spread and long-lived volcanism? In a recent study published in the journal G-cubed (Heyn et al., 2024 ...[Read More]

As we approach the Christmas break and the end of the year, what resonates with the concept of ‘holidays’ more than the Caribbean? In this week post, Angela Gomez-Garcia, postdoc at the Geoscience Institute of Barcelona, and Eline Le Breton, professor at Freie Universität Berlin, take us on a geodynamic journey through the Caribbean Large Igneous Plateau and its enigmatic connection with the Galáp ...[Read More]
