In a recent study published in the journal Icarus, a team of researchers at the International Research School of Planetary Science (IRSPS) located at the D'Annunzio University of Chieti-Pescara in ...

A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists ...

There are 35 large Archean cratons around the world that form the geologic core of tectonic plates. Because they’re located at the interior of plates, these landmasses often remain unaltered over the ...

Here’s what you’ll learn when you read this story: Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even contribute to mass ...

Evolution of endogenic processes is indicated by simulated melt production rate and mare basalt volume. Evolution of exogenic process is indicated by impactor kinetic energy. The points represent ages ...

As Earth formed, new geologic processes, especially those related to the interaction of hot fluids with rock during igneous activity and plate tectonics, gave birth to over 1500 new mineral species (4 ...
