Sentences with phrase «into aragonite»

The researchers also observed evidence that the unstable precursors eventually crystallized into aragonite, the stable form of calcium carbonate that makes up mature coral skeletons.

Not exact matches

But in some cases, droplet - like particles of uncrystallized material known as amorphous calcium carbonate, or ACC, formed first and then transformed into either aragonite or vaterite.

Despite Bart's odd chemistry — extra C03 (and an extra «proton») scavenges Ca from the water column — where it is supersaturated and goes back and forwards into and out of solution as ions or as the solid calcium carbonate (CaCO3) polymorphs of aragonite and calcite predominantly.

I wonder if the described mechanism — CO2 making a hydrogen bond at a surface, then flipping along a fracture plane penetrating deeper into a crystalline material — also works on calcite and aragonite?

The shells are made of aragonite, a form of calcium carbonate (CACO3) that readily swaps out its calcium atoms in favor of heavy metals, locking them into a solid form.
