<正>In the last decade, researchers have been particularly interested in IIa CLIPPIR type diamonds, which differ in composition and physical characteristics from diamonds of peridotite related "P" and eclogite related "E" generations. Moore(Moore, 2009) sought them as mantle kimberlite related megacrysts, but light C isotopy and chemical features needs special eхplanation.
