Researchers have shed new light on the formation of massif-type anorthosites, revealing their origins in the extensive melting of subducted oceanic crust from Earth’s hotter past. This study not only advances our knowledge of ancient geological processes but also has significant implications for understanding Earth’s tectonic and thermal evolution.
By analyzing the isotopes of boron, oxygen, neodymium, and strontium in the rocks as well as conducting petrogenetic modeling, the researchers discovered that the magmas that formed these anorthosites were rich in melts derived from oceanic crust altered by seawater at low temperatures. They also found isotopic signatures corresponding to other subduction zone rocks such as abyssal serpentinite.
Because massif-type anorthosites don’t form on Earth today, the new evidence linking these rocks to very hot subduction on the early Earth opens new interdisciplinary approaches for understanding how these rocks chronicle the physical evolution of our planet.

Scientists pin down the origins of the moon's tenuous atmosphereWhile the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an 'exosphere'—is likely a product of some kind of space weathering.
