※ 引述《oodh (oodh)》之銘言:
: 應該 偏地質 這塊吧
: 還記得 以前學地科的時候 學校教師教
: 現在地球產生氧 的最大量來源 不是植物的光合作用 是岩石的風化
: 我想要請問
: 這樣說對嗎?
: 岩石風化 產生氧氣 的主要原理是什麼?
: 是礦物的還原 還是 氧分子的釋出而已 還是其他的...
: 會同時消耗二氧化碳嗎?
: 又 如果岩石 風亡是氧產生的最大宗
: 是因為岩石多 還是因為這個產生速率本身快 還是因為 植物會進行呼吸作用
: 還是 其他或都有..?
: 希望有知道的人可以回答一下
: 多蝦

你說的應該是這一篇吧
文章的中間有提到
SETI Institute researcher Friedemann Freund has a completely non-biological
hypothesis about the rise of oxygen, which has some experimental support
from laboratory work that he's done. The hypothesis is that, when rocks
solidify from magma, they incorporate small amounts of water.
Cooling and subsequent reactions leads to the production of peroxy
links (consisting of oxygen and silicon atoms)
and molecular hydrogen in the rocks.
Then, when the igneous rock is subsequently weathered, the peroxy links
produce hydrogen peroxide, which decomposes into water and oxygen.
