| Vein minerals are aragonite, barite, calcite, dolomite, quartz, sphalerite, and whewellite. |
| Otoliths consist of calcium carbonate, mainly in the form of aragonite, and organic matter called otoline. |
| Unique for the spectacular stalactites and stalagmites and the formation of needlelike crystals of aragonite, among the oldest of Europe. |
| The fibrous layer, which is made of aragonite and organic material, is elastic only under compressional stress. |
| Many limestones are rich in aragonite, but this in course of time tends to recrystallize as calcite. |
| Strontium concentrations in seawater reflect the diagenesis of Sr-rich aragonite to calcite on continental shelves. |
