The origins of stony-iron meteorites explained

[FfFfFfFF 58,120]

Researchers at the Bavarian Research Institute of Experimental Geochemistry & Geophysics (BGI) of the University of Bayreuth have now succeeded in simulating the formation of all known types of pallasites by means of high-pressure experiments, and in placing them in the history of the solar system. 

As the researchers have now discovered, pallasites arose from asteroid collisions that occurred approximately 4.5 billion years ago. In these collisions, iron from the smaller asteroid mixed with the olivine-rich material in the mantle of the larger asteroid. Billions of years later, quantities of this material mixture were blasted out of the surface of the asteroid by the force of another impact, and catapulted into space. This genesis explains the unusual structures found in pallasites: They contain greenish brown olivine crystals surrounded by nickel and iron metal.

In research, the spatial arrangement of different materials in a rock and the resulting structures make up what is called texture. The pallasites that have been found and studied on Earth so far show a very large variety of textures.

This shows in an exemplary way how these meteorites can provide us revealing and unexpected insights into the early history of our solar system.

It's so pretty
