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、黑雲母、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，黑雲母、榍石等暗色礦物顏色較深，表明其氧化程度較高。
