A new study offers an explanation for unusual chemical signatures found in some volcanic rocks.

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

The internal structure of Earth, structure of the solid Earth, or simply structure of Earth refers to concentric spherical layers subdividing the Solid earth, i.e., excluding Earth's atmosphere and ...

"Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet." These subtle signals were used to map a variable layer of material ...

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls into question some earlier assumptions in planetary science about the early ...

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

Whole Earth structure, earth evolution, cross-disciplinary studies, influence of convection on mantle structure, seismic scattering, core structure, anisotropy, chemical heterogeneity, D00 complexity, ...

The Committee on Solid Earth Geophysics (COSEG) provides independent advice to all levels of government and society on scientific, technical, and policy matters related to seismology, geodesy, and ...
