巴拿马盆地方解石溶蚀的现场研究结果表明，在水深约2800米以下，水柱中的溶蚀速率突然增加。这与表层沉积物碳酸钙含量开始迅速下降或沉积溶斜的深度相吻合。由于在水柱和海底的这种增加的溶解水平似乎与碳酸盐从过饱和到不饱和的转变无关，因此该地区的溶斜可能有一个动力学起源。
The results of an in situ study of calcite dissolution in the Panama Basin indicate that the rate of dissolution in the water column increases suddenly below a water depth of about 2800 meters. This coincides with the depth at which the calcium carbonate content of surface sediments begins to decrease rapidly or the sedimentary lysocline. Since this level of increased dissolution both in the water column and on the sea floor does not appear to be related to the transition from supersaturation to undersaturation with respect to carbonate, there may be a kinetic origin for the lysocline in this region.
