通过对山东蒙阴金伯利岩中富含硅酸盐不相容元素的锶钛铁矿族(LIMA系列)、磁铁铅矿族(HAYI系列)矿物及其相关的钛氧化物矿物的探针成分分析,对比南非Debeers,Jagersfontein及Bultfontein等地金伯利岩区的相似矿物研究,发现这类矿物的产出、相互关系及化学成分非常相近,与共生的金云母、碱性闪石等含水矿物一起,反映了富K,Ba,Ti,Zr,Nb,REE等不相容元素的流体对先前亏损的方辉橄榄岩的交代作用.LI-MA,HAYI系列矿物是流体对镁钛铁矿、铬尖晶石等的继承交代产物.不相容元素的局部富集还可形成一些罕见的矿物相,如REE-Ti及Zr-Ti氧化物.与之相关的呈海绵边或基质、空洞充填产出的钙钛矿、富锰钛铁矿、富锰锌尖晶石、柱红石、铬阿玛科矿等,则与碳酸盐化及金伯利岩岩浆晚期不相容元素的浓聚有关.对这类矿物化学成分及相互关系的研究,不但从微观角度揭示了不相容元素在部分上地幔岩石中的富集,提供了卷入交代流体的总成分目录,而且表明南非和山东金伯利岩地球化学性质的相似性
Based on the analysis of the probe composition of the strontium ilmenite (LIMA series), magnetite (HAYI series) minerals and their related titanium oxide minerals rich in silicate incompatible elements in the Mongolian Kimberlite, Shandong Province , A comparison of similar minerals in the kimberlite areas of Debeers, Jagersfontein and Bultfontein in South Africa found that the output, interrelation and chemical composition of these minerals are very similar and are associated with aquiferous minerals such as symbiotic phlogopite and alkaline amphiboles Fluids rich in K, Ba, Ti, Zr, Nb, REE and other incompatible elements were used to account for the previously depleted hgherolite. LI-MA, HAYI series of minerals is the fluid of ilmenite, chromium spinel, such as the successor to the replacement product. Partial enrichment of incompatible elements can also form some rare mineral phases such as REE-Ti and Zr-Ti oxides. Related to the sponge side or matrix, hollow filling output of perovskite, manganese-rich ilmenite, manganese-rich spinel, rutile, chrome Amaco ore, etc., and carbonate and Related to the concentration of incompatible elements in later kimberlite magma. The study on the chemical composition and their relationship between these minerals not only reveals the enrichment of incompatible elements in part of upper mantle rocks from the microscopic point of view, but also provides a list of the total composition involved in the replacement fluids. It also shows that the kimberlites in South Africa and Shandong Geochemical similarity
