Carbonate is what corals , the shells of shellfish and the outer layers of many photosynthesising plankton and other microbes are made of .
而碳酸盐是珊瑚、贝类外壳和许多行光合作用的浮游生物和其他微生物外壳的组成物质。
As every schoolboy knows , if you drop calcium carbonate ( limestone , for example ) into acid , it dissolves .
每个学生都知道,要是把钙质碳酸盐(比如石灰岩)放进酸里,它就会溶化。
And changes in chemistry brought about by the fossil-fuel carbon now accumulating in the ocean will raise the carbonate compensation depth , rather as a warmer atmosphere raises the snowline on mountains .
If mars experienced a massive impact or its magnetic field disappeared during the early era , the planet 's atmosphere could have been swept away well before carbonate minerals could form .
They concluded " unusual chemical and physical properties " in the meteorite were " intimately associated within and throughout these carbonate disks " .
他们认为,陨石中“与众不同的化学物理特性”同“这些盘状碳酸盐有密切的关系”。
While the lack of carbonate discourages the " warm-and-wet " scenario , it doesn 't necessarily kill the theory .
碳酸盐不存在,使“温而湿”的设想证据不足,但这并没必要否定这个理论。
The work by scientists including dr aubrey zerkle from the university of newcastle in the united kingdom , analysed marine sediments deposited in the campbellrand-malmani carbonate platform in south africa 's ghaap group .
There is evidence that the amount of carbonate in the shells of foraminifera , micro-plankton that are crucial to ocean ecology , has recently dropped by as much as a third .
已经有证据显示一类对于海洋生态极为重要的微生物有孔虫外壳的碳酸盐含量最近已经下降了三分之一。
Jackson said they had identified markers , including changes in carbonate concentration and acidity of the water , concentrations of manganese , iron and calcium which could all be used as early warnings of co2 leaks .
As their report puts it , " this rapid dissolution of carbonate and other minerals could ultimately create pathways in the rock seals or well cements for carbon dioxide and brine leakage . "
