Due to the randomicity , diversity and complexity of distribution of meteorite strike event , the real distribution of plagioclase is pretty complicated , but it is based on the theoretical distribution 由于地球表面隕擊事件分布的隨機性、多樣性以及復合性，有關斜巖實際分布的情況比較復雜，但都以理論分布特征為基礎。

Plagioclase widely spreads across the earth surface , and causes relevant geological movements such as landslide and debris flow , which become one of most broad and severe geological catastrophes 本文采用比較行星學的方法，認為隕擊作為太陽系普遍的地質過程，地球跟太陽系其他類地行星受到隕擊的情況是相類似的。
