titanium

The main element analysis of whole rocks , the ree analysis and the trace element analysis have been done for the granitoid samples in this area . the chemical composition analysis has been done for the amphiboie and biotite minerals . the epma and x - ray powdered crystal diffraction have been done for k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite 對本區花崗巖類樣品進行了全巖主量元素、稀土元素及微量元素分析,對角閃石和黑云母單礦物進行了化學成分分析,對鉀長石、斜長石、角閃石、黑云母、及石英、磁鐵礦、磷灰石和榍石進行了電子探針和x射線粉晶衍射分析。

The microscopical observation proves that the main types of granitoid rocks are granodiorite and quartz monzodiorite , and the enclave is mainly monzodiorite . the rock - forming minerals are mainly k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite , apatite , epidote , etc . the zonation of the feldspars is very popular . the dark - colored minerals , such as biotite and titanite , have been highly oxidized 通過對本區花崗巖類樣品進行顯微觀察研究,知其主要的巖石類型為花崗閃長巖、石英二長閃長巖,其中的巖石包體主要為二長閃長巖,其造巖礦物為鉀長石、斜長石、角閃石、黑云母、石英、磁鐵礦、榍石、磷灰石和綠簾石等,長石中環帶現象比較常見,黑云母、榍石等暗色礦物顏色較深,表明其氧化程度較高。
