| Abstract: | Recently, we collected several thousand cosmic spheres in deep-sea sediments from the Northern Pacific (lat. 7°–11°N, long.
158°–178°W). They include iron sphere (83%), sillicate spheres (15%), and glassy spheres (2%). 5.7% of the iron spheres has
button-shaped structures containing Ni, Co, Cu, Cr, Au, etc.
This discovery is of significance for the further investigation into the origin and formation mechanism of cosmic spheres. |
