| 摘 要： | 本文用矿石显微镜及单晶X射线分析方法,研究了攀枝花—西昌地区铁钛氧化物矿物的显微结构共生组合特点、各出溶相间的关系和分布方位以及不同岩石和矿石显微结构共生组合上的差异。业已查明它们受岩浆旋回和岩石类型所控制。本文指出了磁铁矿-钛铁晶石固溶体显微出溶结构可能是拐点分解经调制结构后的终期产物。

| Abstract: | Fe - Ti oxide minerals of Panzhihua - Xichang district, their
associationof microstructures, the relationship and the orientation among the exsolution phases, the difference of rock and ore in association of the microstructure have been studied by ore microscope and x-ray single crystal research. It is revealed that the microstructure associations of mainly magnetite-ulvospinel-spinel in Panzhihua and Baima mine districts . and magnetite-ilmenits in Xinjie mine district, are controlled by the type of rock and cycle of magma. It is pointed out that the exspluted microstructura probably is the final product after modulated structure by spinodal decomposition. |
