Source of Galapagos eruptions not where models place it
University of Oregon via ScienceDaily
Images gathered by scientists using seismic waves penetrating to a depth of 300 kilometers have found an anomaly that likely is the volcanic mantle plume of the Galapagos Islands. It's not where geologists and computer modeling had assumed.

Goldschmidt2014: Abstract deadline Feb. 8
This is a final reminder that the deadlines for abstract submissions and travel grants are this Saturday, Feb. 8. This year, delegates have the option of submitting two abstracts as a presenting author. Be sure to see our list of sessions as well as abstract submission information for submission procedures. Early registration for members is 590 US$ for delegates and 350 US$ for students. Please encourage your colleagues and students who plan to attend Goldschmidt2014 and are not members of one of the sponsoring societies (GS, EAG, GSJ) to join first, so that they may qualify for the member rate.

Dead plants hold earthquake secrets
With a few tricks borrowed from the oil industry, scientists are hoping to one day better understand why earthquakes start and stop. Geologists would love to know what controls earthquakes. But one of the best ways to answer that question — drilling into faults — is expensive and difficult. An easier alternative is to study faults exposed on Earth's surface, and look at "fossilized" earthquakes preserved along the faults.

Grand Canyon is not so ancient
A longstanding geological fight over the age of one of the most iconic landscapes in the United States — the Grand Canyon — may finally be over. The massive chasm does not date back 70 million years, as earlier work had suggested, but was born in its entirety 5‒6 million years ago when older, shorter canyons linked together to form the complete structure. This explanation aims to reconcile a flurry of seemingly contradictory findings that enlivened discussion about when the canyon was carved.

River roulette: Rethinking how rivers erode
Mother Nature Network
Rivers may seem steady and predictable, but it turns out that they may be a little wilder than scientists once thought. Instead of evenly eating through rock for millions of years, inching downward at a constant rate, rivers erode rock at different speeds through time, according to a recent study.

Opportunity turns 10, makes discovery, shows old rovers can still rock
Los Angeles Times
Opportunity is marking its 10th anniversary on Mars with a little bit of well-earned recognition. The NASA rover was eclipsed in popularity by its much more Wall-E counterpart, Curiosity, when that high-rolling rover landed nine years later. Curiosity was a superstar. This was a sleek, brawny geochemistry lab, the biggest robot ever landed on another planet. And its Twitter feed is consistently adorable.

'Doughnut Rock' added to Mars' mystery object hall of fame
National Geographic
Mars has a way of serving up mystery objects that befuddle and delight us earthlings. Crumbling canals, a mysterious sphinx and now something that looks like a crumpled jelly doughnut have confused and delighted scientists.
