Earth Shaped by Primordial H2 Atmospheres

Nature
Earth's water, intrinsic oxidation state and metal core density are fundamental chemical features of our planet. Studies of exoplanets provide a useful context for elucidating the source of these chemical traits. Read More

Volunteer Opportunities

Geochemical Society
The GS thrives thanks to the commitment of volunteers who support all of our programs. A number of committees and working groups are seeking new members now. If you would like to get more involved in the society, let us know! Learn More

Introductory Student Memberships

Geochemical Society
As an international organization, the GS aspires to have members from all over the world. The society also has a goal of supporting and encouraging students in geochemistry. The Introductory Student Membership program serves both these goals by offering free memberships to students in under-represented countries. The program is open to new student members of the GS who are currently enrolled in geochemistry-related Master's or Doctorate programs in qualifying countries. Learn More

Laboratory Simulation of the Swampy Forest System for the Passive Treatment of Acid Mine Drainage in Coal Mine Reclamation Areas

Scientific Reports
Coal mining that applies the open pit method has the potential to generate acid mine drainage. Acid mine drainage treatments must include processes to mitigate significant challenges; these treatments include active treatment with high costs and process uncertainty and passive treatment with its limitations.

Arizona State University-Led Team Defends Molecular Oxygen Findings

Arizona State University via Phys.org
For more than 15 years, work by a team of scientists led by Ariel Anbar, professor at Arizona State University's School of Earth and Space Exploration, has advanced the case that this biologically critical gas first appeared at least 2.5 billion years ago. Read More

GIS Model for Geothermal Advantageous Target Selection

Scientific Reports
As the particularly popular green energy, geothermal resources are gradually favored by countries around the world and the development model centered on geothermal dew point cannot meet the increasing geothermal demand. Read More

Research Blames Low Sulfide Concentration for Mercury's Lack of Hollows in Smooth Plains

Interesting Engineering
A "surface-space-environment-geochemistry-and-ranging" probe — as part of the Mercury, Surface, Space Environment, Geochemistry and Ranging mission — has resulted in the discovery of hollows on Mercury. Hollows are irregularly shaped shallow depressions that have halos and interiors with high reflectance and are uncommon in the smooth plains of Mercury. Read More

Life May Have Survived Far North of Equator During 'Snowball Earth'

Science
More than 600 million years ago, the planet was frozen from pole to pole, covered in half-kilometer-thick ice sheets that darkened every ocean. How sea life clung on during Snowball Earth, as this inhospitable period is known, has long been a mystery. Read More

Beneath the Earth, Ancient Ocean Floor Likely Surrounds the Core

The University of Alabama
Through global-scale seismic imaging of Earth’s interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published in Science Advances. Read More

Volcano Watch: April Is Tsunami Awareness Month in Hawaii

Maui Now
Gov. Josh Green recently proclaimed that April is again Tsunami Awareness Month for the State of Hawaii. This is not to be confused with World Tsunami Awareness Day, which is Nov. 5. Read More

7.0 Magnitude Earthquake Shakes Indonesia's Main Island

The Economic Times
A strong earthquake shook parts of Indonesia's main island of Java and tourist island of Bali, but there were no immediate reports of serious damage or casualties. The U.S. Geological Survey said the magnitude 7.0 quake was centered 96.5 kilometers north of Tuban, a coastal city in East Java province, at a depth of 594 kilometers. Read More

Geological Confirmation for Water-Effected Incipient Melt Origin of Seismic Low Velocity Zone Beneath Ocean Basins

Science China Press via EurekAlert!
It is accepted that if there were no seismic low velocity zone beneath ocean basins, there would be no seafloor spreading and plate tectonics, but the origin of the LVZ has been under debate for over 50 years as if it is forever unsolvable with certainty. Read More

New Approach Estimates Long-Term Coastal Cliff Loss

Stanford University via ScienceDaily
In parts of California's iconic mountainous coasts, breathtaking beauty is punctuated by brusque signs warning spectators to stay back from unstable cliffs. The dangers of coastal erosion are an all-too-familiar reality for the modern residents of these communities. Read More
