Hot Topic Solar System Earth Geology
 
Mini-Oases at Ancient Methane Seeps
Topic: Geology
05/17/12
Summary: Research shows that ancient mollusks made their homes around methane seeps in the seaway that once covered America's Great Plains.

Yellowstone's Super Volcano Not So Super
Topic: Geology
05/03/12
Summary: New research shows that the Yellowstone "super-volcano" is less "super" but more active than previously thought. The volcano is still large enough to have been responsible for one of the largest known volcanic explosions to have occurred on Earth.

Refining Earth's Clock
Topic: Geology
04/11/12
Summary: Scientists have refined the data used to determine how old minerals or rocks are. The study will help us more accurately date major geological events in Earth's history.

Dinosaurs Roamed a Fiery Landscape
Topic: Geology
04/07/12
Summary: New research shows that fire during the Cretaceous was much more widespread than previously thought.

Fossil Raindrops Reveal Early Atmosphere
Topic: Geology
04/02/12
Summary: By studying fossil raindrops, scientists have revealed valuable information about the early atmosphere of Earth. The research could dramatically improve models of Earth's ancient, and will help astrobiologists understand the environmental conditions in which life arose on our planet.

Discovery Sheds Light on Wandering Continents
Topic: Geology
03/25/12
Summary: New research is providing insight into the processes that underlie plate tectonics. The results could help astrobiologists better understand the processes that led to a habitable Earth.

A New Theory on the Oldest Continents
Topic: Geology
03/15/12
Summary: Geologists have developed a new theory for how the earliest continents on Earth were formed. The processes behind continent formation and development on our planet have a profound effect on Earth's climate and the evolution of life as we know it.

How the Burgess Shale Was Preserved
Topic: Geology
03/13/12
Summary: The Burgess Shale of British Columbia is one of the most important fossil deposits in the world. Now, scientists are beginning to understand how these fossils were preserved.

Green Laser Spectroscopy
Topic: Geology
03/05/12
Summary: LAMIS, a green chemistry laser spectroscopy technique from Berkeley Lab, is faster and less expensive than mass spectrometry and can be carried out from across vast distances. Among other applications, it can be used to date geological objects on Earth and beyond.

Volcanoes Deliver Two Flavors of Water
Topic: Geology
02/28/12
Summary: Scientists have discovered seawater preserved in oceanic plates that could be 1 billion years old.
