Search for Diamonds in the Chondrite Ghubara


IT is generally agreed that meteoritic diamonds are a critical key to understanding the pressure history of meteorites. They are known to exist in four meteorites, one being the crater-forming Canyon Diablo coarse octahedrite (iron), and the others the three known members of the ureilite class of stony meteorites1–4,6. Recent papers5 have summarized the arguments for and against the formation of diamonds by hydrostatic or shock processes.
