1. Plagioclase is a common mineral in igneous rocks.(偏斜石是火成岩中常见的矿物。)
2. The plagioclase feldspar group consists of several solid solution series.(偏斜石长石矿物组包括几种固溶系列。)
3. The composition of plagioclase can be determined by its optical properties.(偏斜石的成分可以通过其光学性质确定。)
4. Plagioclase is an important mineral in the formation of lunar rocks.(偏斜石是月球岩石形成中重要的矿物。)
5. The white crystals in this rock are plagioclase.(这块岩石中的白色晶体是偏斜石。)
6. The plagioclase crystals in this rock display twinning.(这块岩石中的偏斜石晶体呈现出孪晶。)
7. The texture of this rock is dominated by plagioclase crystals.(这块岩石的质地主要由偏斜石晶体组成。)
8. Plagioclase is often found in association with other feldspar minerals.(偏斜石常与其他长石矿物并存。)
9. The plagioclase in this rock has been altered by hydrothermal activity.(这块岩石中的偏斜石已经被热液作用改变了。)
