Study casts doubt on the predictive value of earthquake foreshocks | Geology | Scoop.it
No one can predict when or where an earthquake will strike, but in 2011 scientists thought they had evidence that tiny underground tremors called foreshocks could provide important clues. If true, it suggested seismologists ...

Recent work challenges view of early Mars, picturing a warm desert with occasional rain

Recent work challenges view of early Mars, picturing a warm desert with occasional rain | Geology | Scoop.it
The climate of early Mars is a subject of debate. A recent study suggests that the early Martian surface may not have been dominated by ice, but instead it may have been modestly warm and prone to rain, with only small patches of ice.

Cracking open the formation of fossil concretions

Cracking open the formation of fossil concretions | Geology | Scoop.it
Researchers developed a unified model of the formation mechanism of spherical carbonate concretions, which often contain exceptionally well-preserved fossils. The carbon in the carbonate originates from the organisms preserved inside the concretions, and the surrounding muddy matrix limits diffusion and permeability, and thus causes supersaturation of carbonate at a reaction front. Calcite precipitation occurs several orders of magnitude more rapidly than previously recognized in concretions. This understanding may have practical applications in sealing technology.

New way to estimate magma beneath Yellowstone supervolcano: 'This tells us what is heating the boiler' | Geology | Scoop.it
Researchers have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano. While their findings offer no help in predicting if the volcano will erupt, they can now get a better understanding of a key factor -- a pool of basalt magma recharging the system -- in...
