A new way for life to survive Snowball Earth

Work undertaken by EDRG team members (both current and previous) and collaborators has been published in Nature Communications which helps solve two long-standing riddles in the Snoball Earth hypothesis. Why were there still significant variations in the layers of sediment deposited at that time, and how could life survive?

The world’s largest plagiogranite formed by reworking of juvenile crust, not in a mid-ocean ridge environment as commonly assumed

Published in Nature journal Communications Earth & Environment, the EDRG team and collaborators report the world’s largest known plagiogranite complex in the Eastern Desert of Egypt. Data indicates that the complex was produced by extensive partial melting of the accreted oceanic lower crust (as a proto-continental crust) instead of the previously known mechanisms in mid-ocean ridge environments.

Community Feature Article

 

Prof. Li was recently featured in an article discussing the work that we do in the Earth Dynamics Research Group. The article was produced by Futurum, a magazine and online platform aimed at inspiring young people to follow a career in science, technology, engineering, and mathematics (STEM).

The article also includes a link to an activity sheet for students and teachers. For more information, teaching resources, and course and career guides, see www.futurumcareers.com.

Traveling Geologist

The work of previous EDRG team member, Chris Spencer, has seen him visit many exotic and remote locations around the world, documented on his travel blog Traveling Geologist. The page has now expanded to provide a platform for other Earth scientists to share their adventures – check out some of the incredible photos and stories.
