碳酸钙颗粒在海水中三千多米以上几乎不发生溶解作用,而在三千多米以下溶解速率明显增加。对应的溶解突跃面称为碳酸钙溶解跃面。深海沉积中碳酸钙含量在四千米左右,由多到少迅速减少。沉积中碳酸钙含量只有百分之几或消失时的海洋深度称为碳酸钙补偿深度。在溶解跃面与补偿深度这段深度中,碳酸钙颗粒发生大量的溶解作用。这是地球上
Calcium carbonate particles in the sea water more than 3000 meters almost no dissolution, and more than 3000 meters in the dissolution rate increased significantly. The corresponding dissolving sudden surface is called calcium carbonate dissolved surface. Calcium carbonate content in deep-sea sediments is about four kilometers, more or less rapidly reduced. Sediment calcium carbonate content only a few percent or disappear when the depth of the ocean known as the depth of calcium carbonate compensation. In the depth of the dissolved surface and compensation depth, calcium carbonate particles a lot of dissolution. This is earth
