For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so ...

The giant structures that sit where Earth’s core meets the mantle and slow seismic waves as they pass through could be key to ...

Deep under our feet—almost 1,800 miles below the surface—scientists have found two huge and mysterious structures that may ...

The ultra-low velocity zones (ULVZs) are located around the core-mantle boundary, and most of them are near the boundary of Large Low Velocity Provinces (LLVPs), which dominate the earth’s lowermost ...

A new study in National Science Review have experimentally uncovered a suprising new state of matter within Earth's inner ...

Field examples from the Western Desert of Egypt show the effectiveness of compressional-wave velocity (V p) and shear-wave velocity (V s) crossplots for identifying the type of fluid contained in a ...

In order to determine the influence of shear velocity (U*), bed roughness (k) and moving particle diameter (d) on particle bed-load transport, velocities of single spherical glass beads (Vp) moving ...
