Hammadah al Hamra 346 (Ghadamis). Fresh fusion crust of 98%22/11/2021
Chondrites are called so because they contain chondrules. Chondrules were molten droplets of silicates in space that accreted together with some free metals to form the first asteroids 4550 million years ago. They are older than the Earth.
This meteorite has several characteristics making this piece very striking and beautiful. The shape of this piece allows it to be placed in many ways since you can see the Regmaglyph in one of the corners of the piece, this being very striking due to the place where it is located. On the other hand, a window has been polished to be able to observe the interior and see the breached shape of this meteorite. The color of this chondrite has a nice fusion crust, a thin dark outer layer of rock. Meteors enter Earth’s atmosphere at very high speeds (around 20km per second) so fusion crust is created by friction with the air, heating the surface of the meteor so much that it melts and shines. Because rock transmits heat very poorly, the cold inner part of the meteorite stays cold even as the outermost part is heating up and melting.
