首次在Mir金伯利岩筒中的锆石中发现了烃类包裹体。利用低温荧光光谱仪测定出烃类包裹体的成分为萘和菲的同系物 ,芘 ,1,12苯并芘等 ;其成分与Udachnaya岩筒中的橄榄石内的烃类和Mir岩筒中的石榴石中的烃类的成分相近。测定出锆石的δ13C值为 - 2 1 83‰~ - 3 3 5 4‰ ,与用榴辉岩共生组合中最轻的金刚石测出的同位素δ13C值范围相符。文中引述了有关有机物来源的讨论及多环芳烃 (PAH)由缩聚作用形成的论述。伴生矿物中相当数量的PAH的存在证明在形成金刚石及其伴生矿物的情况下 ,若有相当浓度的自由氢存在则可能发生缩聚作用。这些缩聚作用中碳的来源显然与形成金刚石时碳的来源是相同的 (即液态的CH4,CO及CO2 )。
Hydrocarbon inclusions were first found in zircons in the Mir kimberlite. The composition of hydrocarbon inclusions was determined by the low temperature fluorescence spectrometry, the naphthalene and phenanthrene homologues, pyrene, 1,12 benzopyrene, etc .; its composition and the Udachnaya rock olivine hydrocarbons and Mir rock garnet In the hydrocarbon composition is similar. The δ13C values of zircons were determined to be -2183 to -3354 ‰, consistent with the δ13C range of δ13C measured with the lightest diamond in the symbiotic assemblage of the eclogite. The paper cites a discussion of the sources of organic matter and a discussion of the polycondensation of polycyclic aromatic hydrocarbons (PAHs). The presence of a significant amount of PAH in associated minerals proves that polycondensation may occur in the presence of considerable concentrations of free hydrogen in the formation of diamond and its associated minerals. The sources of carbon in these polycondensations are apparently the same as the sources of carbon in the diamond formation (ie, liquid CH4, CO, and CO2).
