1.【矿】斜长石
1.a feldspar consisting of sodium and calcium aluminum silicates
1.Plagioclase is usually white-colored with perfect cleavage and albite twins.
斜长石通常呈白色，具有完全解理和聚片双晶。
2.Furthermore, the time of plagioclase time distribution can be found by terrane age detection.
此外，可以通过岩层年龄测查找到斜岩时间分布的时间。
3.But measuring the age of lunar plagioclase, samples of which were collected by Apollo astronauts, is fraught with uncertainty.
然而测量由阿波罗宇航员采集的月球上斜长石样品的年龄，却充满了不确定性。
4.Cumulate plagioclase appears abruptly at the base of the F unit , which rests on an erosional disconformity.
堆积的斜长石在位于侵蚀假整合之上的F单元的基底突然出现。
5.Granitic rocks mainly consist of quartz, plagioclase and alkaline feldspar and hence have lower densities.
花岗质岩石主要由石英、斜长石和碱性长石组成，并因此具有较低的密度。
6.An igneous rock composed chiefly of plagioclase and orthoclase, with small amounts of other minerals.
