This paper studies shape of high-pressure phase mineral in naturally shocked meteorites using micro-mine ralogical techniques-TEM.
本文应用透射电子显微镜(TEM)对随州陨石冲击微脉中的高压矿物进行形态观察和电子衍射分析,发现了多晶集合体形态为林伍德石(橄榄石高压多型)、镁方铁矿、镁铁—镁铝榴石(Majorite-pyrope,辉石的高压多形)、细晶林伍德石等,这些高压相矿物的存在可推算出随州陨石熔脉内矿物所受的压力、温度,同时还说明随州陨石熔脉内高压状态的保持时间应较长(数秒钟),这样才能使硅酸盐矿物在高压下进行固态相转变或从熔体中结晶出。
