| Abstract: | This paper is a preliminary study of the structural states, optical properties and compositions of the feldspars in rhyolitic porphyroclastic lava, granite-porphyry and quartzmonzonite porphyry which are typical rocks in Zhengxiangbai qi rock body of Inner Mongolia. It also is a discussion on the forming enviorment of the rockbody. From quartz-monzoniteporphyry, granite-porphyry to rhyolitic porphyroclastic lava, the order degree and triclinity of the feldspars change from high to low, the refraction indexes and axial angles from large to small, the forming temperatures from low to high and the compositions of feldspar are from calcium-rich state to potassium-sodiumrich state. |
