中国科学院广州地球化学研究所谢先德团队研究了随州陨石：高压矿物的宝库。这一研究成果发表在2025年4月9日出版的《地球化学学报》杂志上。

随州陨石是一种严重冲击变质的L6球粒陨石，含有薄的冲击熔融脉。到目前为止，已经从陨石中识别出26个高压相。在高压阶段中，其中10种被国际矿物学协会新矿物、命名和分类委员会批准为新矿物，包括榴石、斜长石、王道钠石、晨鸣石、铁镁石、红柱石、铁硼镁石、黑柱石和黑柱石。

从该陨石中鉴定出的其他高压相有：镁辉石、铁辉石、桥辉石、菱辉石、镁辉石、镁辉石、镁辉石、镁辉石、硅辉石、菱辉石、瓦德利石，以及其他5个相，包括A相、玻璃化B相、C相、D相（富钙镁辉石）和部分倒转的菱辉石。高压相的出现和丰度使该陨石成为迄今为止高压矿物种类最丰富的陨石。

Abstract: The Suizhou meteorite is a heavily shock-metamorphosed L6 chondrite which contains thin shock melt veins. So far, 26 high-pressure phases have been identified from the meteorite. Among the high-pressure phases, ten of them were approved as new minerals which include tuite, xieite, wangdaodeite, chenmingite, hemleyite, poirierite, asimowite, hiroseite, elgoresyite, and ohtaniite, by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association. Other high-pressure phases identified from the meteorite are ahrensite, akimotoite, bridgmanite, lingunite, magnesiowüstite, majorite, majorite–pyropess, maskelynite, riesite, ringwoodite, wadsleyite, and 5 other phases including phase A, vitrified phase B and phase C, phase D (Ca-rich majorite), and partly inverted ringwoodite. The occurrence and abundance of high-pressure phases makes this meteorite the one with the richest variety of high-pressure minerals to date.
