Mid-ocean ridges (MOR) and hotspots are two types of magmatic activity occurring in the ocean. The MORs are typically associated with another tectonic feature—oceanic transform faults. While numerous studies have focused on the interactions within MORs, hotspots, and transform faults, there has been limited research on cases where a hotspot and a transform fault are located at the same end ...[Read More]

Geekology #1, drawing by Lea Pennac.

This week inaugurates a new series of posts: Geekology, fusion of geek and geology. In this section, we will try to unravel tips and tricks of programming applied to geodynamics, from new innovative libraries to good programming practices, interviews with geologists who code and more! To kick off the series, this week’s article is written in collaboration with Baptiste Bordet, doctoral resea ...[Read More]

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]

The question of how we came to be is closely tied with how the Earth became what it now is. What was the early Earth like? How did it evolve to become a habitable world? Given a fragmentary rock record, how can we investigate the early Earth and its evolution? Dr. Junjie Dong from Caltech writes about modeling the early Earth in a two-part blog. For the first part, he introduces the approach to e ...[Read More]
