绿藻+氧化铁 --- 谨记我GG的真言:爱我,喂我,别离开我 |
水中含酸,流经之处,铁矿砂被还原为二价铁,呈绿色;而不久水流改道,原来被还原部分裸露在空气中,重新氧化为三价铁,呈红色。 --- 据说这世界是彩色的? |

Sorry, I don't have Chinese input at home. Try it in English. These are the thermophilic microbial mats found in or/and at hot springs in the Yellowstone National Park. The yellow part is most likely the bacterial mat containing high temperature microbials (>70 degree). (Of course, there may also be some inorganic minerials, such as S and ferric salt). The green part at the edge of stream is the bacterial mat that only tolerates temperature lower than 70 degree. Also, not shown in the picture, there are beautiful blue bacteria found in the centre of the hot springs which can tolerate T higher than 175 degree. 本贴由[salmonfish]最后编辑于:2007-10-4 22:34:41 本贴由[salmonfish]最后编辑于:2007-10-4 22:49:35 本贴由[salmonfish]最后编辑于:2007-10-5 10:2:58 |
