摘要
Diamonds have been reported from Tibetan ＂ophiolites＂ for 〉30 years, but have been widely dismissed as contaminants, because their unusual morphology and light C （δ13C=-18 to -27） are unlike those of kimberlitic diamonds. However, the diamonds have now been found in situ in both the chromitites and the peridotites of ＂ophiolites＂ along the Yarlung-Zangbo suture （Tibet） and the Polar Urals （Yang et al., 2014）.
