This week we have the second part of Junjie Dong’s insightful blog on modeling the early Earth. Following the discussion (“Modeling the Early Earth: Idealization and its Aims I”) about the major early Earth questions and challenges in modeling early Earth, Junjie now explores the imprtance of modeling as a scientific endeavor. He presents how one could more effectively model the ...[Read More]

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]
