carbonate

These calcium carbonate towers, called tufas, formed underwater in California's Mono Lake.(这些叫做石灰华的碳酸钙塔是在加州莫诺湖的水下形成的。)

Sea life makes carbonate shells from this runoff.(海洋生物使碳酸盐的壳流失。)

Inside, lime bonds with the carbon dioxide to form solid calcium carbonate.(在内部石灰与二氧化碳结合生成碳酸钙固体。)

Dr Morris explained that the mineral probably came from carbonate-rich water, which interacted with the rock.(莫里斯博士解释说，富含碳酸盐的水和石头发生反应，从而产生了碳酸盐。)

The fossils buried in Pleistocene and earlier ocean sediments were of foraminifera—small, single-celled marine organisms that secrete shells of calcium carbonate, or calcite.(在更新世和更早的海洋沉积物中埋藏的化石生物属于孔虫类生物，它们是微小的单细胞海洋生物，其分泌的硬壳由碳酸钙和方解石组成。)

"Potassium carbonate is like a vacuum for CO2," Martin explains.(“碳酸钾就像二氧化碳的真空吸尘器，”马丁解释道。)

Corals too started combining the calcium and carbonate that was floating freely in the water to construct reefs.(珊瑚虫也是通过聚集漂浮在水中的钙离子和碳酸盐来建造珊瑚礁。)

If the level of carbonate ions falls too low the shells can dissolve or might never be made at all.(如果碳酸根离子浓度降低超过一定限度，那么贝壳将开始溶解，甚至根本据不会形成。)

The reaction produces a calcium carbonate seal, restoring the slab to its normal load-bearing capacity.(这种反应会产生一种碳酸钙的印迹，并将路面的负荷能力恢复至正常。)

That is bad because many Marine creatures rely on shells made of calcium carbonate to protect themselves.(这是相当糟糕的，因为很多海洋生物生活在钙质碳酸盐的贝壳里以保护自己。)
