Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

The research, published in Earth and Planetary Science Letters, suggests that the thick crust of Mars' southern highlands formed billions of years ago generated granitic magmas and sustained vast ...

During the reawaking of a volcano, magmas migrating through the shallow crust have to pass through hydrothermal fluids and rocks. The resulting magma–hydrothermal interactions are still poorly ...

The research suggests that the thick crust of Mars' southern highlands formed billions of years ago generated granitic magmas and sustained vast underground aquifers, challenging long-held ...

Diamond-laden magmas apparently rapidly rise from deep within the Earth to the planet's surface by jettisoning weight, scientists now find. Magmas known as kimberlites have the deepest origins of ...

Magmas vary in their chemical composition, which gives them—and the volcanoes that contain them—different properties. Since silicic magmas are colder and goopier than mafic magmas, dissolved ...
