A new study shows that giant ore deposits are tightly distributed above where rigid rocks that comprise the nuclei of ancient continents begin to thin, far below the surface (white areas). Redder areas indicate the thinnest rocks beyond the boundary; bluer ones, the thickest. Circles, triangles and squares show known large sediment-hosted deposits of different metals.

Geologists identify deep-earth structures that may signal hidden metal lodes

Our planet has a layered structure of silicate mantle and metallic core. The liquid outer core is located 2900 km below the surface where the pressure and temperature are extremely high, >136 gigapascal (1.36 million atmospheres) and >4000 C. The sound speed and density profiles of the deep-interior of our planet is given by seismological observations.

In a new report, paleontologists Lauren Sallan and Jack Stack re-examine the “enigmatic and strange” prehistoric fish Tanyrhinichthys mcallisteri.

300-million-year-old fish resembles a sturgeon but took a different evolutionary path

Pictured left is an exceptionally preserved male pollen cone of Araucaria huncoensis showing characteristic cylindrical shape and many long, pointed bracts at the base. Pictured right is a leafy branch fossil of Araucaria huncoensis, showing rare preservation of a branching point connecting two leafy branch segments and a connected growth point on the right segment. The branches are usually shed from the tree as individual segments.
