Krotite is a natural
dimorph of CaAl2O4, of which the high-pressure dimorph is named dmitryivanovite
.
Krotite was reported in 2011University of Hawaii at Manoa in Honolulu, Hawaii.[6]
Researchers have found that the mineral, which has the same atomic arrangement as a man-made component of some types of
solar nebula from which the Solar System formed, approximately 4.6 billion years ago. Thus, they are likely to be among the earliest minerals formed in the solar system.[7]
The CAI containing the krotite was said to resemble a "cracked egg" because its rim was crosscut by cracks filled with
aluminum hydroxides. Researchers suggest that the mineral assemblage in the CAI was at one time surrounded by a hot gas that reacted with krotite crystals on the surface of the CAI. It is likely that cracks on this rim of the CAI were filled with hydrated oxides as a result of weathering that occurred after the meteorite landed on Earth.[6]
