文摘

Cement mineral tobermorite was formed in hydrothermal experiments on alternation of calcium–aluminum-rich inclusions (CAIs) in carbonaceous chondrite meteorites. Unidentified bands at 14 µm were measured for CAIs and the matrix of the Allende meteorite sample, as well as for Hektor and Agamemnon asteroids. The presence of cement nanoparticles may explain the feature at 14 µm.
