Hot Topic Solar System Earth Geology
Pinning Down the PETM
Topic: Geology
Summary: Scientists have pinned down the timing for the start of the Paleocene-Eocene thermal maximum.

Building Methane at Depth
Topic: Geology
Summary: A new study shows that methane molecules under high pressures and temperatures in the depths of the Earth can form longer hydrocarbon chains. The work was performed as part of the 'Deep Carbon Observatory' project, which aims to study the presence of hydrocarbons and the possibility of microbial life deep in the planet.

Electric Yellowstone
Topic: Geology
Summary: A new map of electrical conductivity underneath Yellowstone may help scientists understand what feeds the Yellowstone supervolcano.

Wind Shapes Planet's Surface
Topic: Geology
Summary: A new study shows that wind is a much more powerful force in shaping mountains than previously thought.

Oxygen Hogs Delayed Extinction Recovery
Topic: Geology
Summary: A new study shows that prolonged oxygen deprivation after Earth's largest-known mass extinction severly delayed the recovery of Earth's biosphere. The study provides new insight into the causes of this extended period of low oxygen levels.

Quartz is Key to Continent Shifts
Topic: Geology
Summary: A new study shows that quartz plays a key role in initiating the chain events that cause Earth's surface to crack, wrinkle, fold and stretch. The findings could help geologists understand the movements of tectonic plates and their effects on the environment of Earth.

New Study Finds Apex Fossils Aren´t Life
Topic: Geology
Summary: Scientists have been arguing for years about microscopic structures in 3.5-billion-year-old rocks: some think they are the earliest fossilized life yet found, while others see just geology. A new study says the structures are not fossils after all, and cautions that how we interpret such structures will affect our search for life beyond Earth.

Detecting Ancient Earthquakes
Topic: Geology
Summary: A new tool could help scientists learn from earthquakes of the ancient past to better predict earthquakes of the future. Studying earthquakes can provide astrobiologists with a better understanding of how the biosphere on Earth is linked to geological processes of the planet itself.

Earth's Core Provides Climate Insights
Topic: Geology
Summary: By studying the molten core of the planet Earth, scientists have uncovered new evidence that humans play a dominant role in changing Earth's climate. The study could have important implicaitons in understanding the future of life on our planet.

The Redox Revolution
Topic: Geology
Summary: Geologists studying the environment of the early Earth face many difficulties in interpreting the data they gather. One scientist believes 'denser sampling' and 'more judicious reading of rock samples' may help the community solve some of the biggest questions about our planet's history.
