| 摘 要： | 对地表陨石坑岩石和陨石的冲击变质效应的研究， 是以往发现天然高压矿物的主要途径。α-PbO2 超斯石英、(Na,K,Ca)AlSi3O8-锰钡矿以及磷灰石高压同质多像变体等是几个近期在陨石中发现的天然高压相，这些高压相很可能存在于地幔之中。天然高压矿物的发现对地幔矿物学研究和发展起了推动作用。

| Abstract: | The study of shock-metamorphic effects on the rocks of terre strial impact craters and on meteorites has been an approach in searching natura l high-pressure minerals. Recently, several high-pressure phases including α -PbO2， post-stishovite, (Na,K,Ca)AlSi3O8－hollandite and a high-press ure polymorph of apatite, which could occur in the Earth's mantle, have been fou nd in the meteorites. The findings of natural high-pressure minerals have promo ted the development in the mantle's mineralogy. |
