在研究沂蒙矿、蒙山矿等地幔矿物时，新发现了两种Zr－Ti、REE－Ti氧化物矿物。Zr－Ti氧化物新相6个样品点的探针成分分析（wt％）：TIO227.756～46.811，ZrO231.724～58.092，TFeo2.75～5．82，CrO31．728～4．765，Nb2O51．353～4．357，Ta2O50．155～2.814，SiO20．894～13．749，主次元素的成分变化幅度均较大，但以氧为4计算的阳离子总数均为2，因此分子式可简写为（Ti，Zr，Si，Fe）2O4或（Ti，Zr）2O4，与人工化合物ZrTiO4相似。REE－Ti氧化物矿物新相的成分也较复杂，主要元素为REE（Ce，Nd，La，Sm，Pr…）及Ti，次要元素有Nb，根据五个样点的探针分析结果，简化的分子式（Ce…）2（Ti…）3O9，与人工化合物Ce2Ti3O8.7类似，属等轴晶系。两个新矿物相均产于蒙山矿中的微裂隙和熔融交代海绵边中，呈斑点状、蠕虫状、微脉状，组成元素复杂，不同颗粒分析点成分有差异，且在同一微脉中成分也有变化，反映了这两种新矿物相是非平衡的交代一结晶产物。从矿物的产出关系和成分的特征来看，它们的形成与地幔流体交代作用有关。
In studying mantle minerals such as Yimeng and Mengshan, two new Zr-Ti and REE-Ti oxide minerals were discovered. Probe composition analysis (wt%) of 6 new sample points of Zr-Ti oxide: TIO227.756 ~ 46.811, ZrO231.724 ~ 58.092, TFeo2.75 ~ 5.82, CrO31.728 ~ 4.765, Nb2O51 .353 ~ 4.357, Ta2O50.155 ~ 2.814, SiO20.894 ~ 13.749, the major and minor elements of the composition of the range of changes are large, but the total number of cations calculated by oxygen are 2, so the formula can be abbreviated as (Ti, Zr, Si, Fe) 2O4 or (Ti, Zr) 2O4, similar to the artificial ZrTiO4 compound. The composition of REE-Ti oxide minerals is also complex. The major elements are REE (Ce, Nd, La, Sm, Pr ...) and Ti and the minor element is Nb. According to the probe analysis results of five spots, The simplified formula (Ce ...) 2 (Ti ...) 3O9, similar to the artificial compound Ce2Ti3O8.7, belongs to the equiaxed system. Both of the two new minerals are produced in the micro-fissures and molten alternated sponges in the Mengshan Mine, with spots, worms and micro-veins. The compositional elements are complex, the components of different particle analysis points are different, There are also changes in the composition, reflecting the two new mineral phase is a non-equilibrium exchange of a crystalline product. From the relationship between mineral output and composition, their formation is related to the metasomatism of mantle fluid.
