4.5 billion year old concrete from space
...The new mineral (strictly newly discovered in a meteorite) called krotite was found in a high temperature inclusion in the meteorite NWA 1934 that has been dubbed "Cracked Egg". Krotite is named for Alexander N. Krot, a cosmochemist at the University of Hawaii, in recognition of his significant contributions to the understanding of early solar system processes.
Krotite turns out to be calcium aluminum oxide (CaAl2O4) a common component of high temperature concrete used in refractory processes. This material requires minimum temperature of (2,732°F) to be processed in manmade concrete. Low pressure is also a requirement to create the molecular arrangement of refractory concrete.
