本文简短地总结了阿因德陨石的结构要素,并提出了它们的可能起源。在粗粒中CAIB_2型是最原始的;A型(致密型)被认为是在原始太阳系中由B_2型通过B_1型与气体反应形成的。细粒CAI或变形虫状橄榄石包体可能首先凝缩,大部分由深绿辉石组成,具有变质的不透明矿物和富铝辉石。认为这些包体与低温星云气体起反应时,把碱和FeO成分带入包体中,在原始球粒陨石中,那些陨石球粒和球粒状碎屑可能在相同的条件下形成,同时形成了阿因德陨石的母体,
This article briefly summarizes the structural elements of the Al-Malay meteorites and suggests their possible origins. The CAIB2 type is the most primitive in the coarse grains; type A (compact) is thought to form from the B 2 type through the B 1 type reaction with the gas in the original solar system. Fine-grained CAI or amoebae-like olivine inclusions may first condense, mostly composed of dark green pyroxenes, with metamorphic opaque minerals and aluminophosphates. It is believed that these inclusions react with cryogenic nebular gases by introducing alkali and FeO components into the inclusions. In the original chondrites, those meteorite spherules and spherulitic detritus may be formed under the same conditions and at the same time form Al-meteorite’s mother,
