It is possible that thermal alteration would have happened in solar nebula . The high FeO content of olivine ( 29.1 % ~ 34.4 % ) and nepheline ( 4.04 % ~ 9.70 % ) in AOAs suggest the alteration probably take place under high oxygen fugacity .
AOA可能在星云中还经历了热蚀变作用的过程,橄榄石和霞石颗粒均具有高的FeO质量分数(29.1%~34.4%,4.04%~9.70%),表明蚀变反应发生在高逸氧度的星云环境下。
