10硅同位素组成揭示早太古代大陆地壳生长机制显示文摘地球是太阳系中唯一具有厚长英质陆壳的行星,其中30%~70%部分早在3.0 Ga前就已经形成。富钠的TTG(英云闪长岩-奥长花岗岩-花岗闪长岩)和富钾的GMS(花岗岩-二长岩-正长岩)是组成这一阶段地壳最主要的两类岩石,也是理解地壳早期大陆地壳生长的关键,但是目前对于这些花岗质岩石如何从基性源岩演变而来却并不清楚。硅是大陆地壳中最丰富的元素,且具有相似的娃同位素组成。André L Abraham K Hofmann A Monin L Kleinhanns I C Foley F Deng Z B Chaussidon M Guitreau M Puchtel I S Dauphas N Moynier F 袁超 2019矿物岩石地球化学通报2019,38,5:1

19地幔冷却导致大气成分逐渐还原显示文摘直到24亿年前左右的大氧化事件发生之前,大气中的氧气含量可以忽略不计。但是,已有的地质证据表明在大氧化事件数亿年之前光合作用已经开始。因此,对于触发大氧化事件的原因目前还存在争论。一种观点认为,火山气体随着时间的演化变得逐渐氧化是大氧化事件的触发因素。而地幔的长期冷却不仅可以影响热力学平衡,也可以改变火山喷发的还原性和氧化性气体的比例。Kadoya S Catling D C Nicklas R W Puchtel I S Anbar A D 夏群科(编译) 2020矿物岩石地球化学通报2020,39,3:0
