| 中文摘要 | Observations of thin sections of rocks from a fresh and representative specimen of iron ore of skarn type under polarized light microscope, electron probing analyses and Raman analyses for minerals and melt inclusions were carried out. Melt inclusions in garnet have been found. Main characteristics of these inclusions are great disparities in varying sizes and distributions in groups and in zones, the largest melt inclusion is up to 98 mu m x 5 mu m, the smallest one is about 1 mu m x 1 mu rn, the majority of the melt inclusions are 5 similar to 30 mu m in length and 2 similar to 7 mu m in width. Some melt inclusions are scattered within garnet in isolation. They have variety in the shape and they total spindle, dumbbell, string of beads, lotus root, round-like and xenomorphic forms. Stadied skarn mainly consists of garnet with high component of andradite, magnetite, quartz, tremolite and pyroxene, apatite with directional and sporadic distributions, minor zircon and spheric. Melts trapped by melt inclusions in garnet originally consisted of Ca, Fe, Al and volatile components (H, O and CO2) bearing silicate melt. During cooling process of the melt inclusions, hematite, andradite, quartz, calcite and diopside separated out from the silicate melt mentioned above due to slowly cooling, immiscibility of residual melts occurred, Ca and Si-bearing iron melt, Si and Fe-bearing carbonate melt, and Ca. Al, Fe-bearing silicate melt formed respectively. Raman analyses show that the melt inclusions in garnet contain garnet, hematite and calcite; only one melt inclusion contains water vapour. Magnetite mainly contains questionable melt inclusions with silica and iron of variable proportion. Fact that a large number of melt inclusions in the garnet from iron ore of skarn type within diopside-tremolite rock have been found is undoubted. The melt inclusions were observed for the first time in garnet in such type of iron ore, which may possibly invoke new ideas in regard to the genetic study on Shilu iron deposit and how to explore in situ ores from the old mines. |
