It's not gypsum, but speleothems such as flowstone may form from this rock as carbon dioxide leaves solution.
Coccolithophores, the primary biological sources of this rock, are believed to produce less of it due to acidifying oceans. It's not gypsum, but speleothems such as flowstone may form from this rock as carbon dioxide leaves solution. Travertine is a form of this rock that is deposited by hot springs and often contains aragonite, which is a less-stable polymorph of another mineral in this rock which is birefringent. Upon metamorphosing, this calcite-containing rock and its partially-magnesian analogue dolomite turn into marble. For 10 points, name this sedimentary rock which reacts strongly to acid rain, forms stalagmites, and is made mostly of calcium carbonate.
