Topography and exhumation vary strongly along the Apennines, reflecting the geometry of the Moho and different geodynamic mechanisms.
Subduction of continental crust around the Gondwana supercontinent may explain the mantle Dupal anomaly of the southern hemisphere.
Elevated copper isotope ratios in arc magmas from fluid-rich cold subduction zones support the role of oxidizing fluids from the subducted lithospheric serpentinite in the oxidization of arc magmas.
The chemical composition of orogenic igneous rocks and their zircons is sensitive to crustal thickness and can be used to quantify the evolution of Moho depths beneath continents back in time.
Using GRACE satellite data, researchers discovered anomalous gravimetric signals that occurred before a seismic event that started deep within Earth.
Earthquakes as deep as 50 kilometers below the seafloor were detected by 12 ocean bottom seismometers placed around the Challenger Deep.
More accurate aftershock zones reveal that the rupture areas of megathrust Aleutian–Alaska earthquakes are larger than we thought and partly overlap, in contradiction with the seismic gap hypothesis.
Scientists have found holes filled with minerals that indicate fluid-filled pores exist many tens of kilometers below Earth’s surface. But no, The Core fans, you still can’t get amethyst-laden geodes in the mantle.
In our June issue of Eos, we home in on the unique ways researchers are using maps to better understand Earth and beyond.
