Asteroid's troughs suggest stunted planet
A new analysis of enormous troughs on the surface of the asteroid Vesta finds a resemblance between the troughs and surface features known as graben which are usually found on larger bodies, such as planets or moons. The findings may provide further evidence that Vesta differs from typical asteroids by having a layered interior, with a core and mantle, similar to those larger bodies. (2012-09-26)

Super-Earths have long-lasting oceans
For life as we know it to develop on other planets, those planets would need liquid water, or oceans. Geologic evidence suggests that Earth's oceans have existed for nearly the entire history of our world. But would that be true of other planets, particularly super-Earths? New research suggests the answer is yes and that oceans on super-Earths, once established, can last for billions of years. (2015-01-05)

Chinese continental shelf of exotic origin collided with continental China 100 million years ago
Continental shelf is known as the offshore extension of the continent. However, scientists have discovered that the Chinese continental shelf is different. It was an exotic terrain that collided with continental China 100 million years ago. This new understanding helps solve a chain of puzzles on the geological evolution of the western Pacific and eastern Asia since the Mesozoic, including the widespread within-plate magmatism in eastern China as a special consequence of plate tectonics.

Exotic property of salty solutions discovered
Water and aqueous solutions can behave strangely under pressure. Experiments carried out at the GFZ German Research Centre for Geosciences showed that magnesium sulfate dissolved in water was separated less than expected in magnesium and sulfate ions above a pressure of 0.2 Gigapascal. The anomaly is relevant for studies on cold planetary bodies with deep oceans. Christian Schmidt and Craig Manning of UCLA published their findings in Geochemical Perspectives Letters. (2016-11-10)

Earth's crust melts easier than thought
Earth's crust melts easier than previously thought, scientists have discovered. In a paper published in this week's issue of the journal Nature, geologists report results of a study of how well rocks conduct heat at different temperatures. They found that as rocks get hotter in Earth's crust, they become better insulators and poorer conductors. (2009-03-18)

Japan's geologic history in question after discovery of metamorphic rock microdiamonds
A collaboration of researchers based in Kumamoto University, Japan have discovered microdiamonds in the Nishisonogi metamorphic rock formation in Nagasaki Prefecture, Japan. Microdiamonds in metamorphic rocks are important minerals because they form in continental collision zones and show that the crust has penetrated deeper than 120 km below the surface. This is the second area in the world, after the Italian Alps, that shows microdiamonds can form in metamorphic rocks through subduction of oceanic plates. (2020-09-04)

Deep origins to the behavior of Hawaiian volcanoes
Kīlauea volcano typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently. To explain the variability in Kīlauea's eruption styles, a team including scientists from the University of Hawai'i School of Ocean and Earth Science and Technology, University of Cambridge and the Hawaiian Volcano Observatory of the US Geological Survey analyzed 25 eruptions that have taken place over the past 600 years. (2014-04-29)

Permian extraterrestrial impact caused largest mass extinction on earth
What actually ended the Permian Period 251 million years ago? Most Earth scientists blame sea fall, climate change, oceanic anoxia, and volcanism. But that's not so. A group of geologists working in southern China found evidence that an asteroid or a comet smacked our planet, exploded, and then caused the most severe biotic crisis in the history of life on Earth. In the September issue of GEOLOGY, Kunio Kaiho from Tohoku University reports their findings. (2001-08-24)
