Conference Program

Why register for Goldschmidt2021 Virtual?

Goldschmidt2021 may be virtual but will certainly provide lots of opportunities for scientists to present, discuss, learn and network with other delegates.
The pre-conference week is packed with science workshops and early career events.
From 5-9 July, presentations will take place live on Zoom in 15 different virtual rooms, for 2h30 twice a day. In addition, follow up discussions will continue on Spatial Chat, a platform designed for making networking easy and fun.
All registrants will also have access to pre-uploaded content from 28 June to 23 July and will be able to ask questions and connect with other attendees. Recordings of the online sessions will also be available for delegates to view until 23 July.
And last but not least, there'll be lots of fun social and networking events not to miss!

To benefit from the early rates, remember to register by 1 June. Reduced fees are available for students and retirees, with additional discount for members of the EAG, GS and partner societies. Join EAG or renew your membership now.


Call for bloggers at Goldschmidt2021

The EAG is assembling a diverse team of bloggers for Goldschmidt2021 Virtual and looking for volunteers willing to share their first-hand experiences at this year's virtual meeting. Whether you are a seasoned blogger or are looking to gain some experience; a Goldschmidt first-timer, or a hardened conference-goer, we'd love to hear from you! If interested, contact the EAG Office.

Socials & Networking

Take a break from the online sessions and enjoy the social and networking events at the conference. Most of them will take place on Spatial Chat, a platform designed for making networking easy and fun. Highlights will include the Conference Icebreaker, a concert from geo-rock band 'Double Scotch', a pub quiz, wine tasting, the Pride Networking Event, 'Cocktails with Kevin', and much more.
Spatial Chat will be open at all times from 28 June so delegates can use it to catch up with colleagues, discuss over coffee, visit the various spaces including the Early Career room, Exhibition, DEI room, Mentor Lounge etc.

Talking to the media – Tips from Tom Parkhill, Goldschmidt Press Officer

Journalists are human. Like everyone else, they appreciate it when you make their life easy. If you give them a good story, they will be delighted, and they are generally kind to scientists. It can be difficult communicating your story to a non-specialist, but it can also be great fun and allow you to connect with a large audience. Sometimes, our stories can have a real impact, e.g., with public policy. There are no fixed rules in talking to the press, but these notes might help.

Emergence of peraluminous crustal magmas and implications for the early Earth

Detrital zircons from the Jack Hills (JH) metasedimentary belt of Western Australia are a record of the first ∼1.5 billion years of Earth history and can be used to help reconstruct the conditions of crust formation and secular changes therein. Beginning as early as ca. 4.3 Ga, but...

SHRIMP 4-S isotope systematics of two pyrite generations in the 3.49 Ga Dresser Formation        

The 3.49 Ga Dresser Formation has been considered to host evidence of the earliest microbes metabolising sulfur species on Earth. However, previous bulk analyses and in situ measurements conclude disparate metabolisms based on opposite Δ33S1.

An arsenic-driven pump for invisible gold in hydrothermal systems         

Pyrite (FeS2), arsenopyrite (FeAsS) and löllingite (FeAs2) are exceptional gold concentrators on Earth; yet the exact redox and structural state of this “invisible” gold and the forces driving its intake and release by these minerals remain highly controversial.

A genetic metasomatic link between eclogitic and peridotitic diamond inclusions 

Diamond inclusions sample the otherwise inaccessible archive of Earth’s deep interior. The geochemical and petrological diversity of diamond inclusions reflects either pre-metasomatic upper mantle heterogeneity or metasomatism coeval with diamond formation....

Life in a carbon dioxide world

[Nature] Microorganisms living in hydrothermal vents that emit carbon dioxide gas provide a striking example of metabolic finesse. This pathway sheds light on microbial ecology in extreme environments and offers clues to early life on Earth.

New Study on Zircons Finds Plate Tectonics Began 3.6 Billion Years Ago

[Smithsonian Magazine] New research on ancient zircons suggests that Earth’s modern plate tectonics likely formed around 3.6 billion years ago. The paper, published in the journal Geochemical Perspectives Letters, reveals how one of Earth’s defining geologic features likely formed — and set the stage for the emergence of life.

Podcast - Cutting shipping air pollution may cause water pollution, and keeping air clean with lightning

[Science Mag] News Staff Writer Erik Stokstad joins host Sarah Crespi to discuss possible harms from how the shipping industry is responding to air pollution regulations—instead of pumping health-harming chemicals into the air, they are now being dumped into oceans.

Trace seabed plutonium points to stellar forges of heavy elements

[Science Mag] With the discovery of just a few hundred radioactive atoms in seabed deposits, researchers have confirmed that blast debris from a pair of stellar explosions swept across Earth within the past 10 million years—while hominids walked the planet.

Nasa's rover makes breathable oxygen on Mars

[BBC] An instrument on Nasa's Perseverance rover on Mars has made oxygen from the planet's carbon dioxide atmosphere. […] The oxygen generation was performed by a toaster-sized unit in the rover called Moxie - the Mars Oxygen In-Situ Resource Utilization Experiment.

Earth sweeps up 5,200 tons of extraterrestrial dust each year

[Science News] As our planet orbits the sun, it swoops through clouds of extraterrestrial dust — and several thousand metric tons of that material actually reaches Earth’s surface every year, new research suggests. During three summers in Antarctica over the past two decades, researchers collected more than 2,000 micrometeorites from three snow pits that they’d dug.

Tyrannosaurs may have hunted in packs like wolves, new research has found

[The Guardian] Tyrannosaur dinosaurs may not have been solitary predators as long envisioned but more like social carnivores such as wolves, new research announced on Monday has found. […] Using geochemical analysis of the bones and rock, a team of researchers from the University of Arkansas determined that the dinosaurs died and were buried in the same place and were not the result of fossils washing in from multiple areas.
