用微束分析和微区图像分析技术,研究了山东金伯利岩中沂蒙矿(系列)、蒙山矿(系列)、桂红石、Zr-REE-Ti氧化物、钛铁矿(富镁)、钙钛矿和亚铁板钛矿的成分、产出特征和相互关系。这些关系包括:①镁钛铁矿-尖晶石的固溶体分离及伴生的交代作用──沂蒙矿的形成;②蒙山矿的熔融交代作用及其形成的亚铁板钛矿;③斑点、微脉交代充填作用及其形成的柱红石、Zr-REE-Ti氧化物等新矿物相。通过研究,总结了上地幔中与氧化物矿物相关的一些显交代作用的规律,提出了上地幔中不相容元素的显交代作用可分为早、中、晚三期。这些为地幔流体交代作用的总成分目录和机理作出了重要的补充。
The micro-beam analysis and micro-area image analysis techniques were used to study the Yimeng (Series), Mengshan Minerals (series), Cerite, Zr-REE-Ti oxides, ilmenite (MgO) Composition, Output Characteristics and Correlations of Perovskites and Ferrous. These relationships include: (i) the solid-solution separation of magnesiotite-spinel and associated metasomatism ─ ─ the formation of the Yimeng deposit; ② the melt metasomatism of the Mengshan deposit and its formation of the ferrous brookite; The vein is responsible for the filling process and the formation of new mineral phases such as rutile and Zr-REE-Ti oxides. Based on the research, the regularities of some overthrust generation related to oxide minerals in the upper mantle are summarized. It is suggested that the overthrust of the incompatible elements in the upper mantle can be divided into three phases: early, middle and late. These provide an important complement to the catalog and mechanism of the total composition of mantle fluid metasomatism.
