Far beneath Earth’s surface, two enormous structures lie hidden at the edge of the planet’s molten core. These formations, each thousands of kilometers wide, aren’t just geological oddities—they might ...
Two massive, unusual structures, dubbed low shear velocity provinces, have been discovered deep beneath Africa. Scientists believe these formations, hundreds of kilometers thick, are composed of ...
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 ...
